I have been tooling around on my 79 trike EZ-GO with three regular car batteries for a couple months and now I would like to put some real batteries in it . Due to my tight finances I can't afford the six six volt batteries but was wondering what deep cycle 12 volt batteries might be good? I realize my range and so forth won't be as great as it would be witht the sixes but anything will be better than the car bats. I would like to go to a battery or golf cart specialty shop but they seem to have some really high prices around here. Any national chain stores have a decent battery for a decent price? Thanks!!
