More info

This protection circuit is designed for Li-ion/Li-Polymer Battery packs with 20A charge & discharging rate. It provides a cell balancing function after the battery pack is fully charged. PCM will detect each cell's voltage and trim higher voltage down until other cells reach the same voltage level. Therefore, it helps battery cells have longer service life.
