best thing is to get a voltage reducer .....it will still work without just hook lights up to 2 batteries that give you your 12 volts and if you go that way.........which them up every few months so you don,t just always draw on 2 of the batteries........2 batteries for a fewmonths than 2 others for a few months than 2 others.....try and keep the pack as even as you can...........................
