This 1220 mAh, lithium-ion  GoPro Rechargeable Battery  is compatible with the HERO7 Black, HERO6 Black, HERO5 Black, and HERO 2018 cameras. It’s slightly larger than the previous-generation battery yet also has improved charge times thanks to the USB-C rapid charging feature. Additionally, an integrated authentication chip handshakes with compatible cameras communicating exact battery percentage, so you know when it’s time to recharge.
