TOP 3 GOLF CART CONTROLLERS 2021

The controller on your golf cart plays a very crucial role in its working. It controls the acceleration, torque and speed of your golf cart. So, without a working controller, your golf cart will drive unpredictably, and it will not maintain a constant speed. Despite it being so vital to the golf cart, not many people know much about how this device really works.

How Does A Golf Cart Controller Work and Its Importance?

The working principle of the golf cart controller is simple to understand. It alters the power to the cart’s motor, thus allowing the user to control the speed and torque of their vehicle. The larger the controller, the more current it provides, allowing the cart to generate more power.

While this does make the cart go faster, the controller serves more than just this purpose. Regulating the speed prevents excess current and voltage from going to the motor, which otherwise can result in violent takeoff and whiplash. In addition, over-speeding can add extreme stress to the components of the cart.

Golf cart controllers present you with several options, and each one can generate different output levels according to input voltages. The choice of the controller suitable to you depends entirely on the intended usage of the cart. For example, if you are going to use the cart to carry heavier loads or more passengers over rocky terrains, you will need a powerful motor. On the other hand, if you are only going to transport a couple of people or light loads over smooth ground, you will not need a potent powertrain.

Regardless of your choice, here are the best golf cart controllers that we have tested and loved!

TOP THREE GOLF CART CONTROLLERS 2021

Navitas TSX 3.0 600A 36-48V Controller (w/Bluetooth):

Navitas Vehicle Systems was founded in 2011 and has become one of the go-to brands for high-end golf cart and LSV customizers, offering a wide range of products from controllers to motors to AC / DC conversion kits.

The Navitas TSX 3.0 is a clever and durable tool that has a built-in wireless controller. Under optimal conditions, it can go from 0-20 mph in 1.9 seconds making it a powerful upgrade for your golf cart. Although the company does provide a 400/440 Amp variant to this controller, we recommend going for the 600 Amp Navitas Golf Cart Motor Controller because it gives a better experience. You can use the built-in Bluetooth for programming through the app rather than doing it on the laptop to adjust power and torque settings on the fly. In addition, you can lock these setting to prevent younger or less experienced drivers from changing them. Navitas TSX3.0 also has an app that you can use to access a list of the most popular motor maps on the go.
