Features:
1.Battery management circuit board for 11.1V 3S Li-ion and
Li-polymer battery pack;
2.BMS/PCB/PCM applies for 3 cells Li-ion/Li-polymer battery pack;
3.To prevent the battery packs from overcharge,overdischarge,over
current, over temperature ,short circuit ;
4.The Maximal working current: 8A;
5.Compatible with both Li-ion and Li-Polymer cells;
6.With Seiko IC protection.
7.How balancing function works? after 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 cells have longer service life.
