Q: What is the difference between a DC electric cart vs an AC?

A: This question is in regards to the powertrain of the cart. DC (direct current) and AC (alternating current) share the same principles but are not created equal. DC motors use electrical brushes inside the motor that contacts its armature surface where AC does not utilize brushes at all. Because of this, AC motors can be used at a higher RPM so they can create more torque using a higher current. Also the electrical windings inside the motor are much different. In other words, AC motors are able to produce more power without as much work involved. They run cooler and produce power efficiently.

Q: I currently have a DC cart. How do I change it to AC power?

A: To accomplish this, you would need to change out not only the motor but the controller as well. There are kits from Navitas and Silverwolf currently that can upgrade you to this more modern level of performance. You can also tweak and monitor the system via Bluetooth from your cell phone with these kits too. Of course the higher amperage kits produce higher torque and top speed but will require more power to do so.

Q: After purchasing all the parts, is there anything else I will need to do?

A: We recommend spending a little extra and get all new wires in your system as well as a new higher amp solenoid. Starting from scratch allows you to not have a weak point in your new setup. It is recommended to start with a new set of batteries to get the maximum range and performance with your new AC setup. Many people opt to go with lithium now because of its much lighter weight, quicker charging, and no maintenance involved. Not only that lithium has no dip in performance when the battery gets low on charge whereas lead acid or AGM batteries will degrade in performance over time.
