Equalization function
BMS uses the resistor circuit to balance the cell. The cell voltage of the battery pack reaches
3.5V and the voltage of the cell is higher than the lowest single-segment voltage of 50mV, or the
cell voltage exceeds 3.65V to turn on the equalization function. Time (except for overcharge and
full charge) equalization stops.
Note: The equalization voltage can be set.
