Running a Godox AD100Pro flash or the MF-R76 Macro Ring Flash? Then you know you need spare batteries. This is the official GODOX replacement battery pack, models WB100, WB100A, or WB100B (they ship a random version, but they're all compatible from the factory). It's a 7.2V lithium battery that slots right into your AD100Pro flash, giving you the power to keep shooting. They claim it can give you about 360 full-power flashes on a charge, and it helps achieve that super-fast recycle time (as quick as 0.01 seconds at low power). It's also the specific battery for the MF-R76 ring flash. Having a spare (or two) is essential for any photographer – no more missing shots because your flash is charging. Just pop a fresh one in and keep going. Make sure your flash is the AD100Pro or the MF-R76, as this battery won't fit other models. A must-have accessory to extend your shooting time during events, portraits, or macro sessions.
