5. Battery Installation

The FAA-450 uses 1 cell of 18650 LI-ion battery as the internal power source, and there is an battery holder inside its metal
case. For installing a 18650 battery, you need to open its back cover by screwing out the 4 socket head cap screws with the
supplied hex keys.

Picture 3: Screw out the 4 socket head cap screws

Then, open the back cover carefully and slowly, if it's tight, use a rubber hammer or wooden hammer or a screw driver's handle
to knock the back cover out slightly. Do not use to much strength, as this may make the aluminium sheet deformed.
