If you need extra batteries for your GoPro Hero 4, the smatree 1290 mAh will be the best choice. These batteries last longer than any other batteries. The batteries pack includes three batteries, a USB cable, and a charger. The charger has three slots. You will need a wall plug if you don’t have already. Japanese cells, red led light when it needs charging and green when it is fully charged are its main features.
