listen! we use trolling batteries. and we run 6 of the Baja lights from wally world on each side. we have three trolling batteries, 6 light on each and a 3 million candle power spotlight on the third. we can run er as log as we want. usually thats midnight at the latest, but theyed last longer. new batteries last longer than older ones, but it works well.
we took a 1x6 and spaced the 6 lights out on it and put a light switch on it it works really well!
heres a pic of our boat before we updated to the 12 light system. ill get a better pic tomarrow.
