Pin Configuration:
| No: | Pin Name | Description |
| 1 | OUT + | This pins outputs the positive voltage from battery. It should be connected to the circuit which has to be powered by the battery |
| 2 | B + | Outputs positive voltage from USB cable to charge to battery. It should be connected to the positive of the battery |
| 3 | B – | Outputs negative voltage from USB cable for charging battery. It should be connected to negative of the battery |
| 4 | OUT – | This pin outputs negative voltage from battery. It should be connected to the ground of circuit which has to be powered by the battery |
| 5 | IN + | Should provide +5V, can be used if charge cable not available |
| 6 | IN – | Should provide ground of the +5V supply, can be used if charge cable not available |
| 7 | LED Red | This LED turns on while the battery is charging |
| 8 | LED Green | This LED turns on after the battery is fully charged |
Attention!
Before connecting the battery, check the polarity of the plug.
