Hey, I recommended these to you. I've been dealing with Emily Peng over at Shenzhen Basen- she has been wonderful: direct, helpful & reasonable. Big buy, I'm glad that these are what I thought they would be, and- it makes me happy that I'm doing the same (only smaller, of course!).

I purchased batteries from Emily at Basen and have been ripped off.... I'm 4 months in and still have not received my batteries. She says she hopes I will get them by March 15th. I have asked for a refund and now they are ignoring me. Don't buy from this company.

[@rohanwilschefski2549]

I have the same question. That would be my first go to method using my x8. My only thought would be that’s how Mike has been testing pre-built 12v LiFePO4 batteries in previous videos.

[@LithiumSolar]

I guess I just thought that testing a single cell would be a little too plain/boring lol. I haven't decided if I'm going to go through and test one by one or not.

[@liv04soccer]

@@LithiumSolar if these are aluminum cased is there really a need to compress thought that was only for plastic CALB primatics that you had to compress.

[@RolandW_DIYEnergyandMore]

I would say that there is no need of testing brand new cells individually before assembling the pack. They are tested in the factory. Just equalize them by paralleling them before putting the pack together. If there is an outlier in the pack, you will see it on voltage best at low SOC

[@magicmavis]

[@amateurwizard]

Hey found the video interesting. About compressing them, you don't have too it's in the spec of the battery that the enclosure of the cells themselves compress them. The compression thing is 'old-hat' that some people still apply to new batteries.

[@tylerb9808]

My thoughts as well. "To compress or not" I thought it was settled NOT to compress, but rather possibly insert a thin membrane between, to allow natural expansion as opposed to butting them up side by side. I'll keep reading up on this.

[@showbudgies1517]

Ya sure but how long will it last in ofgrid condition using regularly

[@RolandW_DIYEnergyandMore]

@@showbudgies1517, the 3 main factors keeping LFP cells healthy are: C-rate during charge and discharge, temperature profile and compression. Solar Off-grid are typically the easy going applications it terms of C-rate. Big pack, as you want to have stored energy for maybe a few days, and relatively constant loads pulled over long time intervals. Li-Ion cells of any kind prefer warm temperatures, as then the Ions are moving easily through the battery (internal resistance). LFP is feeling very comfortable at 25-35 deg C. Compression, in terms of holding the cells together, don't let them freely contract and expand as they could delaminate internally under harsh conditions. Do all right, and you will get 5000 cycles till 80% DOD while using 90% of capacity at each cycle (3,5V high and 3,0V low).

[@cutweldngrind]

I get confused how to interpret the time the batteries ran the heater. Im glad you used an actual heater.

I don't keep track of the time in these tests. I don't understand why so many ask. It's about the C rate and amp-hour capacity of the battery. I'm curious why the interest in how long the test took?

[@cenchloraadums3143]

A small tip: @ 1:00 if sold as brand new cells, they just don't place a sticker over the existing QR code or scrape it off or do something else obvious. Instead they peel off this top black plastic piece and attach a new one with a fake QR code. In such cases residue of original QR code will still be visible underneath that black plastic strip... I've come across that kinda cells several times. However, concerned the condition of terminals and the fact they have no gaps in between, I think your cells are actually brand new. Failing to put out 280Ah or more in a near 0.2C test is a bit weird though.

[@lnxpro]

should be fun seeing all 32 cells in parallel to top charge balance all prior to putting them in series :)

My understanding about these cells is that they are made without tapped holes. So, there can be markings on them from that process. Does that make sense?

Thank you for your well done video. It's now June 4th, 2021 and I was wondering if you had an update on how they are performing for you. Still all good? Thanks again, G

great review!

Thank you I have been searching the web for answers on the order of connecting BMS to the batteries. If I remember correctly you connected the ground lead to the cells then connected the BMS leads then the black lead. If I have an incorrect idea of the order of connection please let me know.

Only thing that worries me... is getting super used cells like imagine them being originally 310ah cells... used to where they repackage at 280ah. Sure, you get the 280ah but they are several years old. Definatly not saying yours are. I'm sure there is a way to check by measuring the cells like I've seen others do. Diysolar got some cells that this exact scenario happened. The cells were side by side with another group of cells and were larger. Both pulled "rated" power. This has kept me skeptical enough to consider making my own multi round cell batteries. Can you do a tear down on one, as in take wrap off the cell, take the top paper off and see if there is evidence of another QR code or it being another cell? Or do these measure out nicely for them being grade A? Thanks

Great video and thank you for sharing the info on your new supplier. It’s very timely as I am in the planning phase of building my 48v system. Do you mind sharing how you plan to configure yours? I see conflicting stories about pack configs with this chemistry. You also mentioned the 2.2v LVC on the BMS but the recommended cutoff was 2.5v. Will you change to a BMS with the higher 2.5 LVC once you set these up to put into service or keep what you are using now?

I looked at all the comments and it doesn't seem like anybody else noticed this but am I the only one that noticed that at 05:17 the first positive balance lead for the BMS is going on one of the negatives? Isn't it supposed to go to the first positive of the first cell and then work your way up each positive after that?

You checked the conformity of the weight, but not that of the outer dimensions. I have an existing battery enclosure where I think of replacing the cells with those you bought, but they must fit the cabinet. According to the specs published on Aliexpress, they would fit, but did the cells conform the dimensions? If they were any bigger than th spec, they would not fit my enclosure. Could you please check this?

Nice video....What voltage must charge that battery bank (16S) of 51.2V of 360AH so that it reaches 100%?...thanks

[@LithiumSolar]

These cells are 3.65V full charge so with 16 in series, that would be 58.4V full charge.

Awesome video! I have always liked the thorough delivery of the presentations you give, keep up the good work. In the Alibaba website can you give me the name of the exact merchant that sell your batteries? Also I heard you mention in this video with the prismatic cells that you were seeking to sell some batteries, could you send me a list of battery items you have for sale?

[@HotRockCentral]

I visited the link you posted for the batteries you got & something doesn't make sense on the cost. Their site shows 4 packs for $138 so the 32 you got, before shipping cost would be $1,100, do I have that right? You said it cost about 3,500 shipped to your door so the shipping cost was $2,400? That seems to be beyond incredible. What am I missing here?

Nice job 👏.. mentor

Do you have the comms cable to program the bms? My daly bms came with absolute useless settings. Works like a charm now its properly setup.
