Profoto’s B4 is the most powerful battery powered strobe that we stock. Unlike our other offerings, this kit uses the standard Profoto pro-heads. The pack also features a freeze feature (bringing the potential flash duration all the way down to 1/25,000 of a second), and the ability to control each port with 0.1 stop increments.
This pack can also be charged while in use, making it a useful light for studio use or locations with spotty electrical.
Compatible with the Profoto Air remote, but does not feature TTL or HSS.
