915 Generation 6Pcs 2A 5V Charge Discharge Integrated Module for Lithium Ba

If you accept a small load KEY can be connected to the microcontroller about 20s to a low level allows the module to continue working. Trigger mode: low level trigger (ground)
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 the output.
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 , if the load is 50MA, the output will be automatically turned on.
Allow discharge while charging. (Note: At this time output voltage 4.7 / 5V)
Charging current: 0-2.1A
Charging quiescent current: 100uA
Full voltage: 4.2V+ -1%
