6-Hour ActionPack Battery for GoPro HERO3, HERO3+, and HERO4 Black. TheDigiPower Re-Fuel 6-Hour ActionPack Battery extends the runtime of your GoPro HERO4, HERO3+, or HERO3, allowing for six hours of continuous use. The 3200mAh battery attaches directly to the back of the HERO 3+/4 Standard Housing in place of the housing's backdoor and maintains a water-tight seal. Like the Standard Housing, the battery is rugged, dustproof, and waterproof to depths of 131', so it can accompany your GoPro on all of its adventures, both above and below the surface. It weighs in at less than four ounces and features a built-in battery gauge and LED charging indicator. A 2A wall charger and USB cable are included.
