About the GoPro Battery BacPac
Piggy-back your battery to extend shooting time
When I’m traveling with a regular camera, I always have a second battery handy, so I can swap one out to charge up while still shooting. When you’re out in the field with your GoPro HERO3+ or HERO4, you won’t have that luxury. The GoPro Battery BacPac solves that problem by piggy-backing on the battery that’s already in the camera, adding battery power to your camera, which adds to the time you can be out there recording yourself surfing, climbing, skiing or whatever you like to do. It’s also a handy way to extend battery life for time-lapse shooting over longer periods.
