@bakepl what BMS are you using? Did you weight the cells as the EVE spec sheet says 5.2KG per cell. I have 32 of these cells on their way to the UK currently from Aimee at Basen for a 12v and a 48v and should have 12 cells spare all being well.A low volt 1000w inverter alarm sounded when a 60amp load was applied to the 12v battery and then cut out. Cell volts indicated a low volt issue under load from cell two as below....

Disconnected cells, ensured cell two was charged and did a capacity test on this cell. Capacity of the cell came to around 278ah... but this had to be performed at very low amps as cell volt would drop significantly low at around 15-20amps and quickly shut the capacity tester down to it's low volt cutoff... see below

Hello, I just place am order from Basen for the 280Ah also. Did yoiu have a hard time getting the replacement or have do a bunch of proof that there is problem with one cell?

Looks good. Do you know if it has external data logging capabilities?Hello, I just place am order from Basen for the 280Ah also.

I do not think so, it is the same one used by Will.Looks good. Do you know if it has external data logging capabilities?
Hello All New guy here. I ordered 16 280AH from Basen 12/20/2020 and they arrived 2/5/2021 in Los Angeles. Voltages are spot on ( matched ) thus far. They came packed well and included buss bars and hardware.
However several cells looked like rejects. See attached pictures.
