4S 14.8V BMS

Over charge detection voltage: 4.25V±0.025V

Over charge release voltage: 4.15V±0.025V

Over discharge detection voltage: 2.70V±0.05V

Over discharge release voltage: 3.00V±0.10V

1. Protection Circuit Board for 14.8V 4S Li-ion battery pack;

2. BMS applies for 4 cells Li-ion battery pack;

3. To prevent the battery packs from overcharge, over discharge, over current, over temperature, short circuit ;

4. Compatible with Li-ion cells;

5. The Maximal working current: 70A;

6. With cell balance/equilibrium function;

7. How balancing function works? After battery pack is fully charged. BMS 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.
