Ok I have 14 27 watt lights and 6 30 watts 12v deep cycle doesn't last but maybe 3 hours tops. Hard to shoot a 12 hour tournament going threw batterys like that plus a trolling motor battery. Any ideas on how I can make this better? My lights are rigged up daisy chain style. heard about 6v golf cart battery's and running 2 of them and makeing 12v but not sure thanks!
