Perfect for long duration time-lapse photo sessions, endurance motorsports racing or any application where you need up to 2X* the battery life.
Fits Current HD HERO & HD HERO Wrist Housing when used with included backdoors. The Battery BacPac is NOT compatible with the HD HERO 960. Actual battery life may vary.
