Having had a lot of frustrations with my bms not doing what it should, and the fact I only charge through the bms, it would make more sense to get rid of the bms, and use something else to balance the cells. Is there such a product on the market that you can plug into your balance leads, and it balances through the balance leads the cells by passing the voltage around.
for example, say you have a 6s battery whose cells are at: 3.5, 3.8, 3.9, 3.5, 3.9, 4.1. Just leaving this plugged in, it would move the voltages around to balance them to all 3.7 (which is the average).
Does such a thing exist? And for a 10s?
