Portable Awesomeness"The B2 system fits in alongside the B1 system I already own. While both are powered by robust batteries, the B2 uses a separate generator rather than a mono block design. This makes the heads EXTREMELY lightweight but still capable of excellent TTL with the additional AirTTL controller and still capable of using all of my Profoto light shaping tools. There are other small battery operated solutions in the market, but none deliver this level of portability, superlative TTL and support for the Profoto lineup of light shapers. Did I mention that the quality of the light is what you expect from Profoto and better than alternatives? Now I did."
