GoPro Battery Back Pack

A removable battery pack that attaches to the back of Hero3, Hero3+, and Hero4 GoPro camera models and extends battery life.

For optimal performance, calibrate your newly installed battery: Charge it to 100% and keep charging it for at least 2 more hours. Then use your device until it shuts off due to low battery. Finally, charge it uninterrupted to 100%.

A software update may be needed for your camera to work with the Back Pack.
