 Protection Circuit Module for 4 Cells Li-Ion / LiFePO4 Battery Pack

This protection circuit is specially designed for 14.8V Li-Ion / 12.8V LiFePO4 Battery pack with separate charge and discharge function. 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 Li-Ion cells have longer service life. Also the PCM will provide the following protections:

Please select the Battery type, Battery pack voltage via "Battery Pack Voltage?" Option menu.

Over-charge protection voltage, Over-discharge protection voltage & Over-current detection Amperage will be applied correctly based on Battery Pack voltage selection.


  • Apply for 4 Cells Li-Ion / LiFePO4 Battery Pack with discharging current  < 15A
  • Max charging current <10A
  • Internally Trimmed Voltage Limits to balance each cell. Please wait 30 minutes for equilibrium function to take place after charger indicated battery pack is fully charged. 
  • 30A~150A discharge current limit detection
  • Dimension LxWxH : 96mm(3.8") x 64mm(2.5") x 5mm(0.2")
  • Separate charge & discharge terminal


  • If you want to use this pcm for a battery that is rated less than 16A 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 of 0.2V. When charger LED turn Green, allow 30 minutes for pack to balance before use
  • You must be professional in Li-Ion battery pack to buy the PCM. Misusing PCM may cause battery damage or explode.  We are not responsible for any damage caused by user.

Batteryspace is not responsible for any damage cause by misunderstanding and misuse! Please read instruction carefully before assembling.
