The module is adjacent to the differential voltage balance, and the adjacent battery voltage difference reaches 0.1V or more. The internal trigger balance is working until the adjacent battery voltage difference stops within 0.03V. There is an adjacent differential voltage when charging and discharging on The battery pack. Trigger balance, the battery pack voltage error will be pulled back to the ideal value, reducing battery maintenance costs.
