Enclosed is a photo of one of my monolites I'm trying to make more portable for real estate work. It's just a Chinese cheapo, but it's actually pretty good. The downside is that as far as I know, no schematic paperwork is available on it. So even though I am a ham a radio man, I'm not sure enough about the circuitry on this flash where I can tap in and modify it for a battery pack. So, I wonder if there is a portable battery-to-AC inverter I can hook it up to. I wonder about how many watts this would draw. (It's a 600W/S flash). Certainly there must be a small inverter with self-contained batteries I can hang off the lightstand when going on location. I wouldn't need very many flashes out of it on one job. Thank you.
