You could teach a course on the history of golf carts that led up to the Lester 36v or 48v Yamaha Charger. This is the peak of battery maintenance technology, but we have come a long way to get here. Before this quiet, Bluetooth-capable unit, we had big, dumb box units that hummed so loud a better word to describe the noise they generated was scream.Honestly, the sound reduction that this provides is one of its most popular features. That and the automatic multi-voltage support that it provides. Meaning if the plug fits, it will charge it. Another fancy feature that makes these things fly off the shelf is the low level of voltage required to turn them on. Most chargers need at least 60 percent of the voltage to be present to cut on and start charging. This unit can detect and kick on below 15 percent.New batteries? What did you go with? Most of us are sticking with the tried and true wet cell battery technology that we have grown accustomed to. However, the new Yamaha AGM and lithium-ion batteries get supported by this charger as well. It is as simple as changing a setting in the Bluetooth menu of the free app you can download on your phone. Let us tell you when you can check your charge levels on a cold morning just by rolling over in bed; you will see why this is worth every penny.This golf cart charger is very slimline. It is not even half as big as some of the original units that came with the cart. They are leagues quieter as well. Often, you will not tell they are uneven unless you are looking right at it or checking it on the Bluetooth app. So call us today here at Buggies Unlimited and get one ordered.
