Q & A
2S 4A BMS Li-ion Battery Charger Protection Module is a small PCB mounted Lithium Battery charger protection module. This small and intelligent BMS module has features like Short circuits, Overcharge, Over-discharge, and Over-current protection. It is straightforward to install and convenient in all your DIY portable projects.
Li-ion Battery Charger 2S 4A has a Built-in three-stage over-current detection circuit (over-current 1, over-current 2, or load short circuit). MOS transistors 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.
