★ 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. 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 close 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 30 seconds; if the load is greater than 50MA, the output will be automatically turned on.
★ Allow discharge while charging. (Note: At this time output voltage 4.7 / 5V)
