Hello all- there have been a few posts regarding using an SLA charger with different battery types, but haven't exactly answered my question. I just switched to lithium-ion for my ebike from SLA. I am now running two Bosch 36 volt tool batteries (BAT836's) in parallel. To charge them, I tried using the "intelligent" (SLA) charger that came with my hub motor kit, but it charged the two batteries up to 43.3 volts. Do you think the overcharge may have damaged the cells? And why do you think it is overcharging them? Is it ok to go a bit over 42 volts, or is it a strict limit? btw, the cells in these batteries are Konions.
