GoPro Hero4 Rechargeable Battery
One of the great things about the GoPro Hero4 is that is makes it easier than ever to capture your adventure. And with the replaceable battery, you can make sure you never miss a second. The rechargeable lithium-ion battery from GoPro makes it easy to keep recording, even after you've run down the first battery. Before you head out of a long single- or multi-day adventure, just make sure you charge up this spare battery, toss it in your bag, and you'll always have a spare battery when you need it.
