ACEIRMC 6pcs 2A 5V Charge Discharge Integrated Module 3.7V 4.2V for 186 50 Lithium Battery Charging Boost Mobile Power Protection PCB Board Module

4 in 1 Charging / Discharging / Lithium Battery Protection / Battery Level Indicator Module. Lithium battery protection function: over-current, overvoltage, over-temperature, short circuit protection. In discharge mode (The charging mode KEY function is invalid), trigger the KEY port once to open the output; continuously trigger the KEY port twice to close the output. if you accept a small load KEY can be connected to the microcontroller about 20s to provide a low level allows the module to continue working. Trigger mode: low level trigger (ground) The first time the load is connected, the output is automatically turned on. If the load is less than 50MA, the output will be automatically turned off after 30 seconds; if the load is greater than 50MA, the output will be automatically turned on. Allow discharge while charging (Note: Output voltage >4.7/4.7/
