CL 530 amp hour cells are these. It is a high capacity prismatic lithium iron phosphate cell, and apparently, it is designed primarily for energy storage systems. These cells have a nominal capacity of 530 amp hours, a voltage of 3.2 volts, which is around 1.7 kilowatt hours. It can be charged to 3.65 volts and down to 2 or 2.5 volts, depending where you look at. The standard current is 0.5 C or 265 amps. Maximum continuous charge and discharge current is 1 C, 530 amps. Operating temperature for charging is 0 to 60° C, discharging -20 to 60° C. They've got a lifespan between 6,000 and 8,000 cycles. And they've got a weight of around 9.3 kilograms.
Well, so far, nothing outstanding, right? It is just another lithium iron phosphate cell, a typical 3.2 volt cell, and it falls in line with all the other battery cells we have ever tested here on this channel. So, if we wouldn't have the EVE MB56 cell, this CL CB530 would actually be the highest capacity cell you can actually get at the moment. But for now, this is only second place after the MB56 cell.
Guys, welcome back to the Offket garage here in sunny and hot Austral. I actually don't know. I don't know what the weather is outside. I haven't left this room here for the last 4 days. And today we've got 25° inside. And yesterday we had 25° inside here. And the day before yesterday, it was around 25°. But I heard from others that we have 35° C outside. If you are not familiar with Celsius, this is around 220 amps.
All right, in today's video guys, we want to have a look at the CL 530 amp hour cell, also referred to as the CB530. It is really hard to get any information about these cells because CL is not publishing any data of their batteries on their website or anywhere else. CL is not even selling these batteries to the public. So officially, you cannot buy any CL A-grade batteries. Yeah, apparently, they are only selling to other manufacturers. And this is for the A-grade Plus automotive certified cells. So any other CL cell you will find out there is not an automotive grade certified cell, grade A+. So that is very interesting because you can't find online resellers which are selling these CL cells as a grade A+ cell. So most likely, this is not true. However, we have CL cells here in the offcut garage. This one is from the Hakadi battery supertore here. Yeah, this is a 314 amp hour cell which has an intact barcode. And we can try to scan this cell here and see if it works. Let's see if we get a reading. Sometimes a bit difficult with the lighting. Come on. That's perfect. Come on. Come on. Scan it. Scan it. Doesn't scan. Uh, let me try a different scanner application. Uh, well, it scans this one here. Let's see if this is actually the same number. Uh, 4038 at the end. Yes, it is. You've got the same information from this barcode here on the sticker. What a good service. Okay, let's copy this one and say here, enter manually. See what we get. Yes, CL lithium iron phosphate ZBC0000. That's the model code for it. 14.8 Wh. And production city is Fuzhou, Fuzhou, Fuzhou. It's not the Shingman factory as always, like we have with the EVE cells all the time. Number of cells produced 204,038. That is not per day, right? But, um, who knows? CL, largest cell manufacturer in the world. Yeah. And I've got here another 16 CL cells. These are 280 amp hours or so, I think. And they've got an intact barcode as well. Okay, let's see if I can scan this one. This should be easy. Come on. Come on. That's perfect. Come on. Doesn't want to scan. Okay. I typed the code in manually. So, this is as well a CL cell, lithium iron phosphate, 280 amp hours. As I said, good manufacturing date, March 25. This also comes from Fuzhou, and they have produced their, what? 1.21 million of these cells. Definitely not per day. So, yeah, you want to use these cells here to put them in a DIY battery version six, which is coming up here on the channel very soon, 'cause the new version six of the do-it-yourself box has some interesting features I want to show you. Yeah. And I want to use these cells here, and I'm really keen to do, uh, capacity tests on these cells as well and put them in the battery and do a full battery capacity test, and then we can compare them nicely with the EVE cells and see if CL is actually better or EVE is better. Yeah. And I got these, uh, cells here from a company who said these are B-grade CL cells. Well, and looking at them, they look actually used. So, the first thing you notice is they don't have a QR code anymore. The QR code has been wiped out, erased, grinded off. There's nothing anymore. They've got a sticker here with a unique number, but this is nothing like the QR code on the cell. So, we don't have any information about these cells when they have been manufactured. Nothing like this. And you can also see they've got marks all over the place. Yeah. Little scratches here. Some leftover screws from potential labels or so. And someone has tried to clean them a little bit with a terrible success. Um, the top plank cover here is also a bit too short. So, we can see the plank metal of the cell on both sides. And when you measure it, you get 7 volts and 2.5 volts on the other side, as we have seen with other lithium iron phosphate cells as well. So, it is not like that the case is actually the positive or negative. It is somewhere in between. Yeah. And then we have some cells with heat shrink patches, like here, there's a big patch going along this side and one along this side. And here on the other side of the cell, they can see another patch just right in the middle. So, I don't know what these cells went through. Yeah, there are scratches. There's some yellow paint here. Yeah, look at this damage here. So, I'm not sure if these were some test cells from CL or something. I really don't know. And because this company couldn't sell them anymore, they said, "Andy, do you want them for testing purposes here? Do you want to show them on the channel? Build a battery with it and tell a bit about these cells." I said, "Sure, I'll take them. I'll take all the homeless batteries out there and give them shelter here in the air-conditioned battery room." [laughter] So, here we are. We have 15 of these CL 530 amp hour cells. Yeah, I've shown you in the last video already, right? Do you want to see it again? Yeah. There's our number 16. Number 16 had a leak. Something pinched through the box from the outside through the foam and hit the cell. And when I opened one of the boxes, the foam was a bit wet inside. And then I discovered this leak here. Yeah, this was around [snorts] 8 weeks ago or something. And, uh, I took these, um, 12-volt light bulbs here in parallel and discharged the cell completely to 0.00 volts. So, just to get rid of all the energy inside. And at some point, it also stopped leaking. But I think when I start shaking it, I saw some clear liquid coming out. Yeah, it's really like a watery substance. Completely odorless. Doesn't smell. Doesn't taste like anything. I didn't try. Yeah. But since then, it just sits here on this cardboard. Basically, it stopped leaking. And you can see the electrolyte has actually creeped under the heat shrink, under the insulation of the cell. And we've got here a bit of a crystallization. But, yeah, so far, nothing happened with the cell. I don't know how to deal with leaking cells. So, hence, I kept it outside and completely discharged it to 0.0 volts. So, with the next run to the recycling center, I will take this battery with me, put it in a plastic bag, and put a little bit of a note in it what it is, and that half the electrolyte has actually escaped. Yeah. So, unfortunately, we have only 15 of these, um, CL cells at the moment to build a 16S battery, which is not going to work quite well, right? [snorts] But I may have a solution for that. And just to give you a bit of a perspective about the CL 530 amp hour cell, uh, we have here the MB56 cell as a comparison. The CL is a tiny bit higher, and obviously, the MB56 is quite a bit longer. And, yeah, you can see here, this is pretty much the same. There's not much difference. So, I thought, um, until I get a replacement cell of the, um, 530A cell, we can just use the MB56 as a replacement for cell number 16, which then makes our 16S battery, right? Well, we have built Frankenstein batteries before with far more and completely different cells from different manufacturers, different capacities, everything different. I cannot see why an MB56 cell does not fit into this bunch of cells.
>> [music] >> But before we start building this amazing, um, CB 530 amp hour battery, has a 15+1S battery, uh, we want to do a capacity test on these cells here and see how much capacity they actually have. So, 530, do we get 530? Do we get more? Do we get less? Let's find out. Yeah. And interesting with these cells is that the positive terminal is almost square, while the negative is more rectangle-shaped. But someone definitely has welded these M6 studs on top of the usually flat terminals. Now you can see the flat aluminum terminal of this cell. Also interesting, the negative terminal has some kind of copper core. And this is not like just a film. You probably can see the, no, you probably can't. You probably can see the thickness of this copper strip up here. I'm not sure what that is for, but the aluminum terminal is just welded on top of that. So, welded left and right, and the copper goes underneath through this terminal to the other side. Hm. We also have the usual safety valve here. Uh, the QR code, which doesn't exist anymore, and another QR code, which doesn't do anything. The underside is completely isolated, which is good. So, and here we just connect the positive and negative of the CKE Tech EBC A40L, the big Chinese cracker. Turn this one on. Ah, by the way, this is actually repaired here. Yeah, I'll make a separate video about the repair of this, um, battery tester here because in the past, we had some issues with it and it disconnected from the computer, and we didn't know why. So, I got in contact with CKE Tech, and they were so kind and helped me out here. Uh, video is coming.
All right, here we are in the good old EB tester software. Ah, it feels so good. So, our COM 9, we connect with the computer software to the tester, and we want to fully charge this battery first to 3.65 volts. So, charging constant voltage with 40 amps to 3.65 volts, and then we do a cutoff at 0.05 C. I couldn't find any specifications for that because, as I said, CL is not publishing any specifications for these cells. So, you can only get some information here and there online and put this all together. But we go with a standard 0.05 C, which is, um, 26.5 amps. Yeah. 530 amps times 0.05 makes 26.5. So, as always, we charge the battery to 3.65 volts with a constant current of 40 amps. And when we reach 3.65 volts, it holds the voltage constant, and the current will taper off. Once the current is under 26.5 amps, we consider the cell to be fully 100% charged. I'm not sure how full these batteries are. Um, this one is at 3.254 volts. So, this could be everything between 20% and 60-70%. It may take a few hours, probably until tomorrow morning then. But, uh, yeah, let's, um, get this started here. There we go. We can see the current going up to 40 amps. We are charging with constant 40 amps now. And the, um, voltage is now creeping up slowly. But this will be a flat charge curve at the moment because we are already in the middle somewhere. So, I don't know. Okay, we will see us at a later point in life again when this battery is fully charged, and then we do a full discharge test and see what we get. I'm really excited about these batteries here because this is something different. We haven't used here in the Offket garage. Uh, before, we only had mainly EVE cells here. Tested them and used them. We've got a couple of wrapped cells and also some Hythium. Exactly. The fake Hythium cells I got from QSO, but I don't think these were actually real Hythium cells. Yeah. But everything else basically was just, um, EVE cells so far. So, these are the first CL cells we are testing here on the channel. And let's see how much amp hours, how much energy we get out of these CB 530 cells. I will probably do maybe two or three of these batteries just randomly selected, and we do a full charge and discharge test on these just to make sure they are all consistent and, um, we don't have any surprises. Um, while this one is charging here, we can actually check the voltage and, um, internal resistance of the remaining cells and see what we get. I'm actually only looking for an excuse to go back in the nice and cool battery and system room here.
All right, while I prepare the camera, guys, I want to say a big thank you to everyone who has recently purchased these spat t-shirts here on my online shop. Yeah, a little bit of merch going on there. Well, quite a lot of people have bought this t-shirt recently. So, thank you very, very much for that. So, first person I'm seeing with one of my t-shirts out in the wild. You are invited for dinner or lunch then. Okay, we use the near the HRM10. An amazing resistance tester with recording functionality and stand. Okay, at this point of time, I'm not really keen to record any of these data, but, uh, this is more to see what's going on. So, let's see what we get. 3.26 volts and 2 milliohms. And next one, 3.26 volts and 21 milliohms. Uh, 3.26 and 21 milliohms. That's good. I like it. It's pretty consistent. Again, 3.26 volts, 2 milliohms. Just, um, one more over here, then I think we've got a good understanding what's going on. 3.26 volts and 21 milliohms. So, all the same. Yeah, measuring the internal resistance is not really a big thing with these cells because this is just a snapshot of the current situation here, um, in this state of charge and this temperature. As soon as you start using them, the internal resistance will change anyway. So, it is more like testing all the batteries for internal resistance at this point of time now and make sure there's no faulty cell in this batch. Okay, just as a comparison here, we've got the MB56 cell. Yeah, there we go. 3.3 volts and 13.12 I've seen. So, a bit of a lower resistance here because it's a high capacity cell. Yeah, general rule of thumb is the higher the capacity of the cell is, the lower the internal resistance.
All right, my friends. I'll talk to you again in a few hours when this cell is fully charged there. Fully charged. The CB530, 436.9 amp hours we could charge into it before it reached 3.65 volts and the current tapered off to 26.5 amps. It took almost 11 hours to fully charge this battery. Wow. And look at the charge curve. It's interesting that we have this deep knee here at the bottom. But we started at 3.28 volts. Yeah. So, we are still seeing this increase here in voltage at the beginning. That's very interesting. So, we are not seeing this curve starting with a flat line. It is actually increasing, and then we have the flat line here, 3.3 volts. Okay. But now comes the real test. We want to discharge this battery now. So, we click here on discharge with constant current of 40 amps all the way down to 2.5 volts. So, you can find specifications for this, um, CL 530 amp hour battery that you can discharge this cell down to two, down to 2 volts, not 2.5, 2 volts, but this is only for temperatures under 0°. Only a few specifications actually mention that. So, we don't know exactly if this is true or not, but we have seen this with other cells before as well that you can actually go under these 2.5 volts if you need to, if the battery is under 0° Celsius. If this is true or not, I'm not 100% sure. I've never tried it myself. We don't, we don't get these temperatures down here, but we do a discharge test down to 2.5 volts and then call it. That's the end of the line. All right, without further ado, let's get started and we see us again in 12 hours. Oh, this is late at night again. All right, see you tonight.
And good morning and welcome back to. Hey, be careful with the cables. Welcome back to the next morning. I've totally forgotten about this battery test last night, and then I somehow woke up in the middle of the night and said, "The battery, the battery, the battery test has finished." But, um, it doesn't matter because the software runs and captures all the information, and we can easily check out these results the next morning. What we're doing right now. So, here we can see the discharge curve of the CB 530 from CL. So, we have started at 3.65 volts here discharging. You can see this very quick decline to about 3.3 volts here, just after 7 amp hours taken from this battery. Voltage is coming down, 3.3 volts, and then we hold the voltage, and then something interesting happens. You can see we are here at 3.30 volts. Yeah. And here the voltage actually rises again while we are discharging. It rises to 3.3. It's only 4 millivolts, but still remarkable that the voltage is rising for quite a while. 3.305. Yeah, just until roughly here. 4, 3, 2, 1, 0. That's after 180 amp hours taken from this battery. The voltage has risen just by 5 millivolts, and then it dropped down. We have seen this before with other cells as well. And some people believe this is why these batteries are brand new and haven't been charged and discharged much, and all the chemistry inside, they still need to build up and settle down and whatever chemistry is doing inside these batteries. And that's why you have this little hump at the beginning of the discharge curve. So, if this is true or not, I don't know. But not all the batteries are doing this. So, could this be a brand new cell? Well, I don't know. It doesn't look like one. But from the discharge curve, it looks like something is going on at the beginning, and it may point to a brand new cell which has been charged less than five times or so. And then we hold the voltage here pretty much at 3.25 volts. This is the average voltage we are holding. Got a bit of a decline here at 3.3247, and then it goes down to 3.167. Yeah. And this is just before this steep decline of the discharge curve of the voltage, 3.159, and then it goes down. And some people stop discharging at 3.1 volts here. Yeah. So, this is just at the beginning of the decline. 3.1 volts. We have discharged 519 amp hours out of 530 rated for this battery. Yeah. But how much do we have actually left? So, let's have a look. 519 all the way down to 2.5 volts. There it is. 510. And we have discharged the cell with 544 amp hours. So, from 519 to 40, 20, 25 amp hours missing. Yeah. So, it's roughly 5% from 3.1 volts all the way down to 2.5. 5% left. So, it's actually not a bad thing stopping at 3.1 volts. But if you have larger loads connected and you're operating the battery at a low state of charge, and you turn on a motor or hot water system, T-on, or electric vehicle charging, or the compressor of a heat pump. Yeah. So, you have a little bit of a peak, and your voltage of your low state of charge battery dips down a little bit. You can actually reach these 3.1 volt, um, a bit prematurely. I would say it's just for a second or so. But there's still a lot of life left in the battery then. Yeah. So, that's why I always think 3.1 is a bit too early, and 3.0 volts would be a better choice, which is right here. There it is, 2.999 at 529. So, this is 10 amp hours more only, but it is actually in the steeper area of the discharge curve, and it gives you a more defined point when the battery is empty and when you stop discharging the battery then. Yeah, there's not much life left either way, but when you have these loads, these electric motors or heat pumps kicking in, they may prematurely stop, um, discharging your battery then. So, it all depends a bit on what kind of system you have, but so 3.1 or 3 volts should be at the end of discharging anyway, then you have less than 5% left in this cell. So, we have actually discharged 544.10 amp hours. So, that's a 14.1 amp hours more than the cell is rated for. Yeah. 530, and this is roughly 2.7%. Which is nice. Yeah. But if we compare this to the MB56 cell from EVE. Yeah. We got 628 rated, and we have 675 amp hours discharged. So, this was more like 7 and 12% more capacity than rated. 1.76 kilowatt hours out of one cell here is very impressive. And the average discharge voltage here was 3.25 volts. Perfect. So, that is a very good result. We are doing now the charge test, which takes another 13 hours or so. So, probably until tomorrow morning again. Then we have a look at the charge curve. If you can see any of these anomalies like we see in the discharge curve here as well. Well, I wish you a wonderful day, a good night's sleep, and we see us again tomorrow morning. Oh man, these long battery test videos. Insane.
Hello, my friends. Just like this, we've got another morning, another result. And here we have a look at the charge curve of the CL CB530. So, we have started last night, no, yesterday morning actually at 2.7 volts. We can see the steep incline in voltage here up to 3.2 volts. Then a bit of a plateau here. Then a small incline, and then we plateau basically out. We've got another incline here in the middle, which is normal. And then we've got another plateau until this point here. 3.39, we are coming in, 3.4. Here at 3.4 volts, we have already charged 526.7 amp hours. Yeah, it's 97% of the capacity already done at 3.4 volts, but we cannot stop charging at 3.4 volts because 3.4 would be around here, and it would also be around here. So, as you can see, we are still in the fairly flat part of the charge curve here. So, there's no defined point for 3.4 volts. And honestly, with lithium iron phosphate, it doesn't make sense to stop at 97%. You're not gaining any longevity of this cell, any more cycles or so, if you do that. So, and then we go into the steeper area of the curve. And here at 3.45 volts, this is exactly here. That's where we found the battery is charged to like 99% already. And this is where it makes sense to stop because now we've got a fairly high increase in voltage. Yeah, we're going now in this steep section of this charge curve, and every 0.1 amp hours makes a huge difference in voltage. So, there's no point to charge to these areas unless you want to do a top balancing or something. Yeah. And then we finally hit the 3.65 volts here at 541.6 amp hours. The cell starts absorbing for just a small period of time. And this absorption gains us another 0.2 amp hours until the tester turned off because we have tapered down to 26.5 amps with our charging current as well. So, from the extensive testing we have done here on the channel in the past. Yeah, we have determined that 3.45 volts is the maximum we charge the batteries to, and then we keep the voltage constant. Let the current taper off. If the current goes close to zero amps, then we are basically at 99.8% state of charge because the degradation starts when you have high temperatures and also high voltages. Yeah. So, we avoid these high voltages above 3.45 volts unless, as I said, you want to do a top balancing, you go to 3.55 or 3.6 or something, and then the battery is fully top balanced when all the cells have reached it. But daily charging 3.45, and then after absorption time of half an hour, an hour, depending on your battery size, uh, you can fall back to 3.35 volts because this is the natural resting voltage. Yeah. And I'm still receiving many emails from people who are concerned about their batteries being faulty because the voltage actually declines after the battery has reached 3.65 volts, and after a day or two, the voltage goes down to 3.38, 3.44 volts, as we see here, and then it stays there and goes slowly down, and they think the battery is faulty. But this is the natural rest voltage of such a lithium ion phosphate cell. It is not staying at 3.65 volts or whatever you have charged to. Even if you absorb at this voltage, as soon as you take the charger away, the voltage will slightly drop to 3.35 to 3.4 volts. Yeah. So, we have charged 541 amp hours and 1.88 kilowatt hours into this cell here.
All right, my friends. So, what I'm going to do is I pick another two, yeah, another two of these, um, CB 530 cells here and do a full capacity test on them. Charge discharge curve. Then we've got three cells measured out of these 15. So, we should have a good understanding what's going on. And we can also compare these curves quickly and see if there's any major difference, which I don't think it will be. But, um, give me another one and a half, two, maybe three days, I don't know yet, to test another two of these batteries, and then I'll be back here on the channel with the final result of these capacity tests, and we see what we got.
Hello my friends and welcome back to the Offket garage here after a couple of days. So, I was now able to fully charge and discharge to cycle three of these CL CB530 cells. Down here, we can see the results. Uh, capacity 544.9, 545, and 544 again. So, very, very consistent, which I'm very glad about. Up here, we can see the discharge curves as well of all three. I did a bit of an overlay here. So, we've got different colors, but you can see they are very close together, which is very, very nice. So, it looks like these cells are somehow matched and they bring us a consistent capacity and also average voltage 3.25 volts for all three cells. Perfect. I haven't only tested the, uh, CB 530 cells, but I've also tested the CBC00. Apparently, that's from CL as well. This is a 314 amp hour cell, uh, the guys from Hakardi have sent over for testing, and I have also tested one of the 16 CL 280 amp hour cells EVE Power has sent over. We will put these ones here into the DIY version six do-it-yourself case very soon. So, expect a full and comprehensive review of this do-it-yourself box. And we not only want to have a look at the discharge capacity of these cells, but want to compare them to the EVE cells, um, as well. Yeah, because we have the MB31 which has 340 amp hours rated as well. How is it called? Yeah, the LF280K, the older series of these cells as well. So, let's talk about the CATL530 first. We have discharged this battery with 544, 545, and 544 amp hours. So, this gives us an advantage of about 2.8% more capacity than rated, which is great. If we compare this to the MB56 from EVE, which is a higher capacity cell, so it's not really 100% comparable, but, um, this, um, MB56 cell gives us 628 rated amp hours. And we managed to get around 675 amp hours out of the EVE cell, which gives us an advantage of 7.5% more capacity than rated. Now, this is almost three times more than the CL cell provides. So, big advantage here for the EVE cell. And if you look at the 314 amp hour class, we've got the CL cell here. And I managed to discharge this cell with 323.2 amp hours. Yeah, this is again 2.9% more capacity than rated, which is fantastic. And looking at the EVE MB31, uh, this is one from Yishi Young. And I could discharge the MB31 with 330.6 amp hours. And this gives us an advantage of 5.3%. So, again, more than the CL cell can deliver. And then the CL 280 from EVE here, I could discharge this cell here with 303 amp hours. So, this is a really, really good result for the 280 amp hour cell, over 300 amp hours. Yeah. And let me have a look at the, um, EVE LF280KL cell. I have a lot of results here. So, I looked through all my battery tests and found some, uh, certified automotive grade cells, and they discharged with 294, 289, and 284, which is a bit less than 5%, while the CL 280 gives us 8.2%. But I've also have some LF280K cells from Google Power, which measured with 302. So, this is comparable with the CL cell, and also 299 amp hours. And then the last EVE delivery of LF280K cells from Yishiang delivered us 304, 303, and 303 amp hours. So, exactly the same as the CL cell, but I think these days people are not buying the LF280K version anymore. They always go for the MB30, MB31, or even now for the MB56. Yeah. So, this was just a bit of a comparison between CL and EVE. How much extra capacity you get with these cells. And it looks like EVE is here the winner. This is just one random supplier of the CL cells, Dongguan Lithium Energy Technology, wherever that is, and they are selling the CL 530 amp hours for $88. So, that's actually a good price if you take 1 to 99 acres. Yeah. But we can also see that these cells here don't have any welded studs. So, it might be that this reseller sells these CL cells as they come from the factory. Yeah. Without any welded studs, and then you have lost basically because then you cannot connect any bus bars without having a plasma welder. And that's why these resellers usually weld M6 or M8 studs onto these aluminum terminals of the cells. So, it makes it far easier for the do-it-yourself community to connect any bus bars and balance cables and whatever. Yeah, but here, one battery, $88. Not bad. Uh, here's another reseller, Guangdong Jingyi New Energy Co. They are selling the same battery, uh, for $98. That's the 530A. And then the rear capacity over 580 amp hours for these cells, which we haven't seen with my cells here. Actually, this is just a screenshot here. I cannot look what the price is for that. But obviously, they have done some testing and have, um, sorted out these cells which are performing better and selling them to a higher price. I mean, fair enough. But here as well, flat terminals. Yeah, there's nothing you can connect to it without a plasma welder. So, pay attention if you buy these cells that they have welded studs on it. So, then we have a look at the MB56 cells. This is from our friends from QSO. For example, the MB56 with 628 amp hours, which is in reality 680 amp hours of real capacity actually. Yeah, 'cause here at QSO, $108. So, between $10 and $20 more in comparison to the CL 530, but you're getting far more capacity out of these MB56. Uh, here's another price for the MB56 grade A. They are selling it for $98. So, exactly the same price as for the CL. So, why would you go for a smaller capacity when you get a far higher capacity with the MB56 for the same price basically? So, that's why I said the CL 530 amp hour cell is a good cell. It's not bad, but it seems to be a bit outdated now and overrun by the EVE, uh, MB56 cell, right? Far more capacity, same price, and we're getting all the support from the manufacturers for these do-it-yourself kits for the MB56 cell. While for the CL cells, there is no do-it-yourself kit available out there because CL is mainly selling to other manufacturers like BMW and Tesla and everything to use their cells in their vehicles. And only a small portion of their cells makes it actually into the do-it-yourself community for solar storage. So, that's why most of the people go with EVE cells for home battery storage.
All right, my friends. There you have it. The CL CB530 here on the test bench. We've done the discharge test and also compared them to the other cells and also the EVE cells as far as it is comparable. As always, you find the information and data about all these cells down in the video description. I'm uploading all these test results to my website. There are already tons of battery tests available. You can download the CSV files coming from this tester here, and also the graphs. There are BMP files you can look at which have also all the data on it. And you can also download the CKE tester software for your computer and import the CSV files to see the curve and study the voltage and capacity for each of the points. And the good thing is you don't need a tester for that. And also this information are completely free of course.
All right, my friends. Leave your comments down below if you have CL cells as well. What capacity did you get out of your cells? I'm really interested to hear that. And in one of the next videos, we want to build this new Frankenstein battery there with the CB 530 cells from CL plus the one EVE MB56 cell. It will be very interesting how we manage to get the bus bars between all these cells and how this all works out. And of course, we will do a capacity test on this battery as well then once it's fully charged because we should get around 27 kilowatt hours out of this battery pack then. So, which is quite impressive again.
All right, my friends. So far this video today. Thank you very, very much for all your amazing support. Especially thanks goes always to these people who are buying me a spat, a solar panel alignment tool. And if you use such a tool yourself, make sure it is ice cold. Oh yeah, some of you up there only need to put it outside. It is winter and bitter cold. As always, more videos are coming soon. They're already in the pipeline. If you want to leave a nice comment, give me a like, and if you're new here, subscribe. Until the next video, you stay charged, stay safe, and thanks again for watching. See you then. Bye-bye.
