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

BMS D725V2 for 22.4V 7S LiFePO4 Battery Packs (10A Charge, 10A Discharge)

1. Protection Circuit Board for 22.4V 7S LiFePO4 battery pack;
2. PCM applies for 7 cells LiFePO4 battery pack;
3. To prevent the battery packs from over charge, over discharge, 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.
7. 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.
