MakerFocus #ad - 4 in 1 charging / lithium battery Protection / discharging / Battery Level Indicator Module. Mcu users, 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.

Lithium battery protection function: over-current, overvoltage, over-temperature, short circuit protection. Trigger mode: low level trigger ground. If the load is less than 50MA, the output will be automatically turned on. Allow discharge while charging. The first time the load is connected, the output will be automatically turned off after 30 seconds; if the load is greater than 50MA, the output is automatically turned on. 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. Note: at this time output voltage 4. 7 / 5v.
