Nothing else besides the stereo draws much and even the stero is minimal compared to the lights.

Gotcha so that's ballparking roughly 2.5hrs per battery on an average 100 amp hour rated battery to power the lights. Not bad for that all out purpose built system! If I run just a couple lights I think I could have enough juice on board to have some shooting fun.
