Product ID # 6218
Part Number:
PCM-SM8



This protection circuit is specially designed for 12.8V LiFePO4 Battery pack with 20A discharging rate. Different than normal PCB, it provides equilibrium function 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 LiFePO4 cells have longer service life.

All Lithium Battery packs must connect to a protection circuit module to protect Battery from overcharge, over discharge, short circuit  and accidental explosion due to its extra high energy density.
