Eventually, but not yet.
I have no way to measure cell voltage manually and have to rely on the BMS, i only have 4 shallow cycles on the packs at 72v, I want to see some consistency for a few cycles before i do a full capacity test.
I have 2 different chargers, a 2 amp and a 4 amp, end of charge using each charger varies + or - 1v so i don't know if this is related to the Ballancing feature of the BMS or if it's caused by the ambient temp or some other satanic doing... .. one pack settles to 41.4v, the other tends to be 41.8 to 42v...
