BesTech 3S 50A PCM/BMS for Li-ion/Li-Polymer/LiFePO4 management system 11.1V/12.6V 9.6V/10.8V with balance
1.Protection Circuit Board for 11.1V 3S Li-ion and Li-Polymer battery pack;
2.PCB applies for 3 cells Li-ion/Li-Polymer battery pack with E-Switch integrated, E-Switch can totally turn off the output;
3.To prevent the battery packs from overcharge,overdischarge,over current, over temperature ,short circuit ;
4.With cell balance/equilibrium function;
5.Compatible with both Li-ion and Li-Polymer cells;
6.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.
We do custom BMS. If you like this BMS, but the continuous current you need is less than the maximum continuous current supported by this BMS, we can do this.
Please feel free to contact us. and the price will be lowered accordingly. Please be noted, thank you.
