As indicated in the mechanical drawing, the connectors correspond to the cables which they are to be attached with.

### LEDs & Switch

Power Tag comes with multiple LEDs. The status LED indicates the voltage level of the battery at present. You can simply click the button as shown to check the battery charge status at present. The LED combination which will light up is based on the voltage reference values (minimum, nominal and maximum voltage) provided during setup.
