Installing the Flight Battery
Once the Li-Po battery has been fully charged, it’s ready to be installed in
the Ember 2.
Install the battery in the Ember 2 by pressing it to the battery tray with
the label facing downward and the connector oriented toward the back
of the airplane.
Note: Be sure to press the battery against the battery tray so the
battery is secured by the hook and loop material.
