This 1220 mAh, lithium-ion GoPro Rechargeable Battery is compatible with the HERO8 Black, HERO7 Black, HERO6 Black 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.
