Ok, I´m going to try it
just to confirm, so basically connecting a rc charger to 1s, on negative (13) positive (14) (that should be the correct polarity, isn´t it?) until that group is at same level, is that correct?
Thank you so much for the tips guys...
a cell group that seems to drop out is not always a due to a bad cell, when using adaptto bms.
i have had similar problems, and naturally thought the worst, but after changing the max cell charge V/balance regime, it sorted itself out(surprisingly)
after a discharge, try to set max cell V to 3.89 volts and ballance to 3.88v. for example, and slow charge at 3 Amps or something.
somehow, it seems the high cells can get "out of range" of the balancing function. maybe its just a adaptto glitch, wouldnt surprise me.
the lg pack i had issue with was showing similar behaviour to yours, but when i changed the settings it stayed ballanced for ~1year afterwards from memory.
another thing it might be worth checking the real group voltages with a good meter and calibrating the bms voltages accordingly.
