i see "voltage difference large"#2 is at 0.5 on the trouble maker and at 0.8 on the well behaved BMS. dont know if that makes any difference

this is from the trouble maker, as you will see both has the firmware update as you suggested

ok so this one is from the bms that works fine

oh well, I guess that didnt work. got up at 4 am and checked the system and the same bank is offline again. I didnt bother to go pull the wires off to reset it as the other bank was at 65% soc, so I just went back to bed. I think what I will try today is to swop the bms with the one that...

understood, but since Ive done that initial balance they seem to be fine, when the charger goes to FLOAT, the BMS shows each of the 32 batteries in both banks relatively close. the actual figures in bank one last evening were 3.538 3.532 3.526 3.539 3.531 and so on. however by sundown...

my 16s/280ah bank took 8 days for all the cells to reach 3.65v then i configured them to series and immediately the bms was showing 3.35 -/+ .05 on each cell, and that happened when i top balanced my both banks of batteries . im still puzzled but i just let them be
