2008 EZGO golf cart with lithium batteries and an on-board charger good tires brakes lights and front headlights you'll never have corroded battery cables or have to add water to your batteries or have a frozen battery with lithium batteries  we were able to takes 400 lb off of the cart so the cart will run a lot better and fastert this  is a never die system which means that you can turn the batteries on and off and when you turn them off and come back a month later or longer and turn them back on they will be at the same charge level as they were when you turn them off
