5V 2A Lithium Battery Charge and Discharge Protection Module

The lithium battery protection module is used as a control circuit for charging and discharging a 1-cell lithium battery. This module has the possibility of protection against overvoltage, overcurrent and protection against short circuit, as well as protection against temperature increase, which provides an output voltage of 5 volts and a charging current of 2 amps. The 1-cell lithium battery charge and discharge protection module has several LEDs on it, each of which indicates the remaining charge percentage or the charging percentage in progress. Among the other features of this battery charge and discharge protection module is the 5 volt output capability, which can be used to charge mobile phones and other devices with 5 volt charging input.
