Fuel your adventures with this DigiPower Re-Fuel RF-6H34 Lithium-Polymer Battery, featuring up to 6 hours of battery life per charge. The water- and dust-resistant design also includes a micro USB port and USB cable so you can plug into your camera.
If you love using your GoPro without having to worry about charging it frequently or having to change out the battery every-so-often like me this is perfect for you & well worth the price it cost.
