Protection Circuit Module Specifications  For 6.4V LiFePO4 Battery Packs

This protection circuit is specially designed for 6.4VLiFePO4 Battery pack with 20A discharging rate.  Different with normal PCB, it provides equilibrium 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:

  • Keep 6.4V  LiFePO4 Battery pack from overcharge ( 3.850+/- 0.025V per cell )
  • Balance each cell at Max. 3.60 +/-0.025V per cell ( required voltage tolerance within 0.2V for each cell)
  • Keep 6.4V  LiFePO4 Battery pack from over-discharge (2.10 +/- 0.1V per cell)
  • Limit 6.4V  LiFePO4 Battery pack's discharging current below 20A.



  • Please don't use the PCM for lower capacity or low drain LiFePO4 pack.  Make sure your LiFePO4 Battery pack can handle 20A drain current before buying
  • To achieve balance, each cell in battery pack must has equal voltage within 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.
