We bought our 1989 CC From Wayne's golf cart service at West coast battery builders in Indio CA. Delivery was prompt and the cart was better than described. They have many modern carts too
It is a great example of a clean un-molested 80s Club Car deserving modern electronics. We bought new 8v batteries knowing our kit and the motor would support 48v operation.
48v is not needed but it does produce 33% more speed and torque from the stock motor. I expect we will go from 12 mph to 18 mph with the voltage increase.
