This battery is used when the JooVuu X needs to be away from a power source, eg. when used as an action camera or on a drone.
The 660mAh battery is custom designed for the JooVuu X. It provides approximately 1.5hours recording time.
The battery can simply be installed by unscrewing the 4 holes on the bottom of the JooVuu X case, unscrewing the metal lens ring, lift off the back of the case and unclip the capacitor, then remove the capacitor. Next, clip the battery and place the battery in the desire position and then screw the lens ring and back of the case back together. The whole procedure takes 1-2 minutes.
