The NEW Lester Summit II Multi-Voltage 36V/48V Battery Charger can be INSTALLED ON-BOARD OR USED AS A STATIONARY CHARGER ON ANY 36 VOLT OR 48 VOLT GOLF CART that take the above pictured Andersen SB-50 plug. Most commonly used on 36V EZ-GO Marathon/Medalist golf carts (1983-1995) and for a variety of 36/48V floor machines such as Advance, Nilfisk, Nobles, Alto, Tennant, Factory Cat, Clarke, and others. If you're driving a hovercraft, and it's 36V OR 48V with an Andersen SB-50 receptacle, it may even charge that, too.

It's the best charger we've ever tested. We asked if it knows C3PO and it said that he's really pretentious in person.

It is an automatic battery charger so once your golf cart batteries are completely charged the battery charger will automatically stop charging, no manual shut offs required. (Unlike your last charger, it does what you need without asking) The LED indicator lights let you know when the smart charger is charging, done charging, or if there's an issue with your batteries. Don't forget that it's also drop proof and water resistant, so you can leave it out in the rain, snow, sleet and hail... Don't leave it along for too long, though. After a few glasses of wine it may lose its keys and start calling its ex's.

This new heavy duty industrial build also features cleaner, more efficient charging and a Blue Tooth App for tablets and mobile devices that allows you to view charge cycle status, choose or upload new charging profiles, and much more! (Some customers have told us it's smart enough to run for president.)

The development team at Lester Electrical has designed this Summit 2 golf cart charger to be the most advanced, versatile charger with the most features and user interaction ever! This high quality, American assembled product comes with a 4-year warranty (covers everything) and bragging rights that your charger looks like it should be strapped to your back playing Halo. Order yours today from one of our Customer Care Specialists at (800) 401-2934 to see how quickly the best new charger on the market can get your EZGO golf cart up and running and get you back to work!
