I recently snagged the K&F Concept 3 Pack Hero 13 Camera Battery with Charger for my GoPro Hero 13 Black to keep up with my action-packed YouTube shoots, and I’m seriously impressed with this kit. As a content creator already using a Canon R5 with a 7artisans 35mm T1.05 lens and K&F Black Mist filter, I needed reliable power for my new GoPro to capture biking and hiking b-roll without constantly swapping batteries. These 2100mAh Enduro batteries deliver, giving me around an hour of 5.3K 60fps footage or slightly more at 4K 60fps, which is plenty for my fast-paced shoots. The 3-slot USB-C charger is a total game-changer—it charges all three batteries in about three hours, has clear LED indicators, and doubles as a storage case with slots for two microSD cards, keeping my Lexar 512GB card safe. The batteries are fully compatible with my Hero 13, slotting in smoothly with no error messages, and they feel sturdy with safety features like overcharge and overheating protection. That said, the runtime is just a tad shorter than GoPro’s OEM batteries in high-demand modes, and the charger’s three-hour cycle feels a bit slow if I’m in a rush. There’s also no detailed battery percentage display, so I plan ahead by charging overnight. I haven’t tested them in freezing conditions yet, which some reviews suggest might be a weak spot, but for my mild-weather shoots, they’ve been rock-solid. This kit’s a lifesaver for keeping my GoPro powered during long sessions, perfectly complementing my SmallRig RGB light and Zhiyun Crane 2 setup. For any vlogger or action filmmaker, these batteries and charger are a fantastic way to stay in the game without missing a shot!
