4S 16.2V Lithium Battery Protection Module

Description:

The lifespan and health of batteries depends on the amount and time of their charging and discharging, and the protection module is used to control the voltage applied to the battery. The battery charge and discharge protection module is designed to keep and protect the battery in a particular voltage range and prevent overcharging and discharging.

BMS or Battery Management System module is used to protect and control the charge and discharge of lithium ion or polymer batteries. Battery protection modules are usually classified based on the amount of current and the number of battery cells they support, and this product is a 4-cell lithium battery charge protection board with the power to protect voltage up to 16.8 volts and current up to 18 amps, and the voltage protection circuits are more than It has limit, over current and over temperature.
