Ive just taken delivery of 3 x TB47's. Still can't get the 48's here, the supplier says they're all going to the US!! Anyway, the 47's give me a pretty good flight time.
I read that the 47s were shipped with the unit because its the largest battery you are allowed to fly with? Is there any truth to this? I flew though Switzerland with a whole profoto light kit and they did give me a hard time (but eventually let me though).
