I have never thought of using Golf Cart batteries, but I'll keep that in mind. I usee the WalMart Maxx batteries and have have good luck with them. I use a 24V minn Kota Trolling Motor and I can get 2 days of trolling out of them with no problem. I am on my 4th year with these batteries now and I can't help but wonder when they will let me down. I can't say anything bad about them at all.
