The used Battery BacPac v4 is an accessory back with integrated rechargeable battery that attaches to select GoPro camera. Key features include:
Increased Battery Life. This model offers a 15% increase in capacity over the previous generation GoPro Battery BacPac v2 for Hero3+ / 4.
Charge via USB. The included USB cable is used to charge the Battery BacPac via your computer’s USB port or a widely available USB power adapter (not included).
GoPro Compatibility. While this product is technically compatible with all GoPro cameras (HERO4 and older), the included backdoor will only fit the “standard housings” that are included with the GoPro HERO3+ and the HERO4: Black Edition / Silver Edition cameras.
Standard Hero3+ BacPac Backdoor. This version of the Battery BacPac v4 includes the standard bacpac backdoor to fit the GoPro Hero3+ standard housing. It will not fit the original GoPro HERO3 housing.
