The Battery BacPac attaches to the back of your GoPro in order to double the battery life. With the new door for your waterproof housing you are able to add longevity to your experience. This is great for long rides when your camera is on for hours. It is also great for cold rides when batteries simply don't last as well as they do when it is warm out.
This Battery Pac Kit includes one Hero3 battery and is compatible with the Hero3 camera only.
