Starcgreen

this is rated for 1S battery, the operating voltage is 3.2V to 4.2V. It supports 2A of current. This is a Battery Management System circuit that monitors the charging and discharging profile of the battery. 

The task of battery management systems is to ensure the optimal use of the residual energy present in a battery. In order to avoid loading the batteries, BMS systems protect the batteries from deep discharge and over-voltage, which are results of extreme fast charge and extreme high discharge current.

The role of a smart Battery Management System (BMS) is to monitor and report the associated battery's health, performance, and maintenance. The vast application of smart BMS range from data centers, hospitals, banks, telecommunication towers, energy storage stations, and more.
