Li-ion / 18650 12.6V 3-Cells Battery Charger Protection PCB Board (up-to 20-Amps Peak Current)

  • RM12.00

  • Product Code: Li-Po 3-cell protection module
  • Availability: In Stock


This Li-ion / 18650 battery protection PCB protect a Li-ion / 18650 batteries with 8A continuous current. Protection is critical as a Lithium-ion batteries could explode when they are shorted circuit or overcharged, and damaged when they are over discharged.


* Note:  First time usage (no output load) will require a 12V power supply to activate this module.
