Extending the life of your GoPro HERO, the Battery BacPac is a removable battery pack that seamlessly attaches to the back of the camera. This version features a 15% boost in capacity compared to the previous model – perfect for all-day adventures, marathon surf sessions, or any application where you need more battery life than the internal battery alone can provide. It’s also ideal for activities where charging or swapping in a fresh battery is difficult, like scuba diving and overnight backpacking. You can charge it with any standard USB charger, the GoPro Auto or Wall Charger (available separately), or a computer. A USB cable for charging, BacPac Backdoors, and a protective case are included along with it.
