Li-ion Battery Charger Protection Module 2S 3A Charger BMS Protection Board Module is a small PCB mounted Lithium Battery charger protection module. This small and smart BMS module comes with various features like Short circuit, Overcharge, Over-discharge, Overcurrent protection. It is straightforward to install and convenient to use in all your DIY portable projects.

Li-ion Battery Charger  2S 3A   has Built-in three-stage over-current detection circuit (over-current 1, over-current 2, or load short circuit). MOS transistor can control the battery charge and discharge.

Therefore a BMS may also feature a precharge system allowing a safe way to connect the battery to different loads and eliminating the excessive inrush currents to load capacitors.
