Trojans golf cart group 31s. If you have the money go straight to them. If not get what you can. Started with 27, then 29, then 31, then the golf cart 31s. Have to get 31 trays for them. You can notch out one side of a 29 tray and make it work but make sure batt are strapped secured. They are taller so measure first. Fish with what you can and just learn how to eliminate water and max your batt time. Good luck. Cranking is two things. One addictive and two cash consuming. Lol
