lens pirate, I read on the link that you say you use the Powerbright 600 unit, I have just put together my power kit with the same unit, using the same battery as a Vagabond2. I have a question for you, when you fire your lights, do you get a small beep after every shot because in quick testing I did get a beep with the AB800full power and the 1600 also. Not on the 400 though, i guess it is just not as powerful, but is this normal? I am waiting for a new set of powerbright cables 8 gauge to come in the mail and my setup will be complete and was thinking also it may be the cables I am using right now causing it to beep. Sorry to original poster, did not want to hijack the thread, I was just reading it and clicked the above link and saw lens pirate was using the same inverter as me, thanks.
