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.
