The 1000mAh 11.1V lithium polymer battery is attached via a connector, making it delightfully easy to remove.

The second connector is a balance charge connector, which ensures that each of the three battery cells is charging equally, thus optimizing capacity and prolonging battery life.

The battery contains a protection circuit module, which prevents it from discharging too rapidly, over charging, or short circuiting.

Parrot claims the battery will only last about 12 minutes after a full charge, which takes around 90 minutes. Taking your AR.Drone out to the park with only one battery won't get you much play time, unfortunately.
