8S BMS 60A NTC Sensor LiFePO4 Protection Board Balance PCB Battery 3.2V
8S BMS 60A LiFePO4 Protection Board Balance PCB Battery 25.6V 3.2V Sensor und Stecker 22V 25V
Mit Temperatur Sensor/Schalter
?1.Protection Circuit Board for 28.8VV 8S LiFePO4 battery pack
2.PCB applies for 8 cells LiFePO4 battery pack with E-switch integrated, E-Switch can totaly 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 LiFePO4 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.
