Protection Circuit Module (PCM) with Equilibrium Function for 24 cells (76.8V) LiFePO4 Battery Pack at 60A limited (#5191)
|
|
see notes
Product ID # 5191
Part Number: PCM-LFP76.8V60A
|
This protection circuit is specially designed for 76.8V LiFePO4 Battery pack with 60A 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.

Warning
- If you want to use this protection circuit board for a battery that is less than the rated drain, you must add additional protection device to protect the battery itself. Such as: proper rated polyswitch.
- To achieve balance, each cell in battery pack must has equal voltage within tolerance. When charger LED turn Green, allow 30 minutes for pack to balance before use.
- You must be professional in Lithium battery pack to buy the protection circuit board. Misusing may cause battery damage or explode. We are not responsible for any damage caused by user.
