Everything else is simply Series drive. Series drive is used for the workhorse carts.
The Series drive carts are better suited for off road use, moving heavy loads, and slow going.
Generally the Sepex drive carts produce more speed and less torque. They are the people movers. Sepex drive makes a great neighborhood cart and recent developments make them more able off road. More about the XCT controls later.
Generally speaking a 400 amp controller will handle most street & campground applications in both 36 volt carts and 48 volt conversions. However addition of rear seat and bigger tires can create a need for the 500a control even with the stock motor.
A 36v motor run on 48v produces a 25-33% increase in torque and speed. On 48v the motor consumes less amperage and this reduces heat (a motors worst enemy) and increases the run time.... this is a win win situation. If you have a 36v series cart that lacks power and speed 48v is the performance boost you are looking for. More info here 36 to 48v upgrade
Off Road enthusiasts, Hunting Buggies, & Carts used for hauling Farm & Ranch materials should use a 500 amp controller. As mentioned above carts with rear seat, big tires, and used off road or on hills need 500 amps
Anyone looking to upgrade their motor for more speed or torque should consider a 500 amp controller.
500 amps handles the biggest Sepex drive motors
500 to 700 amp Controls handle the biggest series motors
