Profoto AcuteB2 600Ws AirS LiFe Power Pack

Profoto's AcuteB2 600Ws AirS LiFe Power Pack supplies 600Ws of portable flash power in a compact, lightweight (7.9 lbs/3.6 kg) package, with the most advanced long-life battery (a Lithium Ion Iron Phosphate, or LiFe, battery) now available. The AcuteB2 gives you everything you want in portable power--up to 200 flashes at full power, super fast recycle time (0.08-2.0 seconds), flash duration as short as 1/6800s, and variability over a range of 7 f-stops (9-600Ws). The LiFe battery gives you up to 4 times the battery life of previous batteries. Plus, the built-in Profoto AirS radio sync receiver provides control from up to 980' (300 m) away (with AirS radio trigger, available separately).
