Li-ion / 18650 12.6V 3-Cells Battery Charger Protection PCB Board (up-to 8-Amps Peak Current)

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.

Features
