BMS/PCM/PCB - LiFePO4 BMS/PCM/PCB

BMS D706 for 38.4V 12S LiFePO4 Battery Packs (20A Charge, 20A Discharge)

1. Protection Circuit Board for 38.4V 12S LiFePO4 battery pack;
2. PCM applies for 12 cells LiFePO4 battery pack with E-Switch integrated, E-Switch can totally turn off the output;
3. To prevent the battery packs from over charge, over discharge, over current, over temperature ,short circuit;
4. Compatible with LiFePO4 cells; 
5. 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.
6. PCM comes with all the voltage detection wires and connectors.
 
We keep materials in stock only, we need around 3-7 days for samples productions.
