4. Function Description
4.1 The PCB is applied to protection of three-cells lithium-ion battery pack, which is set
according to requirement of customer.
4.2 Overcharge protection:
The overcharge protection operates when voltage of cell more than VCU with charger at P+
and P-, then charge will be stopped and discharge will be allowed.
