I couldn't wait for the Vagabond II, so I decided to build my own (with the help from previous threads here).
I purchased the inverter from the link below, and I am not sure if I got the right one. It will not charge more than one strobe at a time (AB800's). I plugged in three 100 watt bulbs and the inverter ran just fine. When I try to I fire two strobes, it shuts down and a buzzer goes off. I am using two 12 volt batteries that show a full charge.
Any ideas. I need this for an outdoor shoot tomorrow.
