If you cart has Lithium batteries, then you need a lithium specific battery charger to keep them fully charged and maintained. Don't let anyone tell you otherwise (regular deep-cycle chargers can damage your lithium batteries).
So get your Club Car 48-Volt LITHIUM Battery Charger from Allied Lithium, and keep your lithium batteries in tip-top shape.
This charger will bring your batteries up to full in a shorter charging time and then maintain them at 100% until the cart is used.
