The battery manager that is built in (BMS) to the battery pack measures each cell voltage and will disconnect when parameters are breached. It also balances the cells with a resistive load if one becomes more than another.This only happens when a cell is above a set voltage, it will not happen...
Tried a half day hire on a full suspension ebike- wow so much fun. 2 trek rails ordered the next day. Still got some analogs too. Can't wait for next week
Cheers
