BMS we use is designed to "shunt" power from cells that fill up first, allowing all the cells to "catch-up" at the end of the charge cycle. Basically balancing the pack everytime. Only problem i have had with balance was on a cell whose BMS board had failed to control overvoltage (cell was reduced capacity & replaced). Our current bms has the ability to disable the cart if voltage goes too low, and shut down charger if any cell goes too high. We do bring them in for checkups (check terminals, Bms operation, and charger).
