This is the Battery Box for PowerBrick, it is used to supply power for the Armourbit and its modules, motors and servos.

It has capacity for 1 18650 Li-ion battery and uses a 3Pin PH2.0 connector for output. Comes with a built-in Micro USB port with short circuit protection for charging.

Also comes with a USB Type A output port to power other modules such as Robotbit, KOI AI Camera.

### Precautions

* Install the battery before turning on the power.
* Beware of the polarity when installing the battery, refer to the polarity labelled inside the battery compartment.
* Remove the insulation wrapping of the 18650 Li-ion battery before using.
* Take out the battery when not in use for a long time. Keep it in a suitable place.
* Do not short the battery connectors with a metal object.
* Avoid over charing or discharging of the battery, charging should only be done under supervision.
* In case of over current or short circuit, the protection circuit would activate and switch off the power. Troubleshoot and fix the problem before restarting.
