Yamaha is one of the finest golf carts on the market. But if you are a do it yourself-er like we all are, finding the golf cart parts to repair it yourself can be pretty tricky sometimes. We like to help with that problem by carrying various products for each machine, including the 48-Volt 300-Amp Controller from GE. This brain box is an aftermarket item, and it's going to look quite a bit different than the one that came on the golf cart. It will plug in the same way and come with a wiring diagram to clear up any confusion.It is a 300 amp unit, meaning it's a little bigger than the stock one from the factory. You will get a slight increase in speed and torque. We know what you are thinking after reading that, "that's great, but what about my runtime?" You get a boost on that, too, due to an increase in power use efficiency. With all that in-store, you need to call Buggies Unlimited and get one coming today.
