Smart Li-ion BMS 25.9V PCM 7s 12A Battery PCM for Li-ion Battery
Packs 7S26A PCB BMS 7S PCM 26A
Product name: Protection Circuit Module
Model No: PCM7S26A
For 7S lithium-ion/Lithium polymer/LiFePo4 battery packs
Cylindrical Lithium battery (Li-ion)
Prismatic Lithium Polymer battery (Li-Po)
Feature:
1.Protection Circuit Board for 25.9V 7S Li-ion and Li-polymer
battery pack;
2.BMS applies for Li-ion/Li-polymer battery in series;
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.
