Running out of battery during an outdoor shoot is the last thing you need. With a B10 series battery, you get extended battery life. A fully charged battery delivers over 400 full-power flashes with the B10 or B10X, and 200 with the B10 Plus or B10X Plus. You can quickly swap the battery in and out of the flash. An integrated charge indicator lets you check the charge at a glance. The battery recharges quickly with the Profoto Battery Charger 3A and is UN certified, so you can take it on flights.
