Thanks you all. I will test the 2p4s. It seems to me to be the easiest way to make a large capacity battery. Its likely to be hard to find a box to accommodate 8 cells ? Thank you community for your valuable information.

Hi, ahhh ok I see more clearly. What I don't understand is to use a bms 4s? Because if two cells are in pairs, they will necessarily have the same voltage? I have 8 EVE cells bought directly from EVE factory, never used, just top balanced

Hello. I have 8 280ah cells lying around, I was wondering if it was possible to make a 12v pack. If I make two 4s packs and I connect these two packs in parallel is what I can do so 12v 560ah ? In theory I can, with a single bms 8s, do this project? Thank you for your advice and experiences.

It's really not bad! But there is no Walmart in my country. I'll still see if there is an equivalent here. How did you do your two terminals (+) (-)?

This is awesome ! Is there a chance to find this kind of box on Aliexpress to have a better price?

Hello, I ordered on DocanPower a 4s LF280k. But I forgot to order a box to build the battery. Can you recommend me a seller of quality box and not too expensive? A box that can therefore contain 4 cells. I am looking for a seller on Aliexpress, Alibaba or a reliable website. Thanks for...

Oh great that's good news! I was afraid that stud was welded. I have a hope of repairing the cell. I will post a photo in the afternoon I will disassemble the battery but basically the stud is broken at the base of the aluminum square. Thanks for the hope :) (I use a translator to communicate so...

Hello, I accidentally broke the terminal of an EVE brand lifepo4 cell. This is the LF230 cubicle with the square terminal. Tightening the bolt, the screw cut flush Do you know if the screw can be extracted or is it a screw sealed to the cell If it's sealed do you have an idea to repair the...

Hello, I am looking for an EVE brand cell. This is the LF230, the one with the square terminals. As it is quite urgent I am looking for a seller in Europe if possible for fast shipping. With a bit of luck .... Thank you and good day

hi @mikefitz to finish this story, I broke the screw of a cell by tightening the bolt too hard. so I have a cell out of service. obviously no European seller sells these cells. So it's going to end up in the back of a closet and I'm going to go back to agm batteries. Thank you all for your help...

hello, I reassembled the battery in 12v. the cells are at 3.55v therefore 14.2v overall.with the multimeter I have a voltage of 13.75v at the battery terminals. I think it's not too normal that the voltage is not equivalent to the voltage of the cells.... If ever someone passes by to reassure...

@On_The_Road @Bud Martin @Substrate Hi. I wanted to ask you a question, is it normal for the load to be at a maximum of 3.62v? And today the cells are at 3.59v even though I didn't use them. Thank you very much for your help

Hello. the charge is finished since this morning (finally!) The charger amps are down to zero but the cells are only at 3.62. I hope it's going to be ok, I'll set up the BMS and wait for the sun to see if my problems are solved

Ah okay, I misunderstood your message, I'll try to find thicker cable. the more the battery is filled, the more the amperage goes down. It's been almost a week of charging and still has 3.34v on the cells.

Hi. Thanks for the advice, I actually use the original alligator clips. I will cut out the alligators and replace with ring terminals Édit : I installed the ring connectors. I still have 3.57 out of the charger but there is now 5A coming out
