Question: are all gopro batteries compatible?
Answer: If you're upgrading from the HERO4 Black and wondering whether you can use batteries from the HERO4 Black or Silver in the HERO7 Black, HERO6 Black, HERO5 Black, and HERO (2018), the answer is no. The HERO4 batteries are different and can't be used interchangeably. At left is the new battery for the HERO5 Black.
