3 BAT: Battery
4 GND: Battery -
5 GND: output -
6 VOUT: output
7 KEY: trigger
Note:
1. In discharging mode(charging mode KEY function invalid), trigger KEY one time,output open; trigger two times, output close.
2. Output will open automatically if you connect load. If load below 50MA, the module will turn off output port; if load over 50MA, output port will always open.
3. Allow charging and discharging at the same time(output voltage should below 5V. Stop charging and stop discharging,you should reactivation the module.)
