PCM with Equilibrium Function for 7 cells (22.4V) LiFePO4 Battery Pack at 40A limited

Protection Circuit Module Specifications For 22.4V LiFePO4 Battery Packs(7 cells)

This protection circuit is specially designed for22.4V LiFePO4 Battery pack with40 A discharging rate. Different withnormal PCB, it providesequilibrium function during charging, e.g. PCM will detect each cell’s voltage and trim higher voltage until other cell’s voltage reach same, therefore allow Li-ion cell has longer service life.Also the PCM will provide the following protections:

• Keep22.4V LiFePO4 Battery pack from overcharge ( 3.90 V/cell )
• Balance each cell at Max. 3.60V/cell +/-0.3V( required voltage tolerance within 0.2V for each cell)
• Keep 22.4VLiFePO4 Battery pack fromover-discharge (2.00V/cell)
• Limit 22.4V LiFePO4 Battery pack’s discharging current below40A.

Warning:

• Please don’t use the PCM for lower capacity or low drain LiFePO4 pack. Makesure your LiFePO4 Battery pack can handle 40A drain current before buying
• To achieve balance, each cell in battery pack must has equal voltagewithin tolerance of 0.2V.
• You must be professional in LiFePO4 battery pack to buy the PCM. Misusing PCM may cause battery damage or explode. We are not responsible for any damage caused by user.
