Profoto has introduced the B10 Off Camera Flash (OCF). This versatile and powerful light is actually very compact—about the size of a coffee can—yet it provides up to 400 full-power flashes per charge.
The B10 OCF comes with a Li-Ion battery, a 3A charger, stand adapter, protective cap and a case. A Duo Kit is also available with includes two heads, double the standard accessories, and the Core Backpack S. They can be controlled by a smartphone app and Profoto Air Remotes for a variety of camera systems.
If I were in the market for units more powerful than speedlights, I would look real hard this system. Watch the video!
