No expert, never seen this device up close, but here is my opinion.

This is a device made for Club carts that do not have the speed code set to 4 (max on club car). Club car has 4 speed codes in the controller that can be set by a CC dealer. A cart with speed code set at 3 will go about 14 MPH ( speed codes 1 and 2 are slower). A cart with speed code set to 4 will almost go 20 (I think 19.7 MPH).

Looking at the device, my guess is this device works by lieing to the controller's speed sensor.

In the demo video, he first goes without the device on a cart that can go 14 MPH. He puts pedal to metal and the controller starts giving the motor volts. The controller senses the motor speed and when it reaches 14 MPH it stops giving more volts.

The second part of his demo with the device in line, he does the same test. He puts foot to the floor, controller giving motor enough volts to go 14, but this device tells controller we only going 8, so controller gives more juice, I suspect up to the full 48, but I have never had a volt meter on one.


This device has no way to increase the speed of a club car with speed code 4 (already goes 20). The device cannot invent voltage. Just under 20 is as fast as that stock motor and controller can go with 48 volts.

If your cart is set to go 14 or less, I would call a couple of CC dealers first to see how to get it set to speed code 4. Should cost $100 - $150, but that price is a rumor.

PS. If you have one that goes slow, needs batteries and you wish to get rid of, let me know. I will be there soon and looking for a fun project.
