About module pin
1 VIN: charge port +
2 GND: charge port -
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.)


Package Includes:
1 x power module
1 x button
