Upgrade your golf cart’s stock DC controller with a Navitas TSX3.0 Separately Excited (SEPEX) intelligent controller. These plug-and-play kits replace the OEM controller while keeping your existing motor and harness—delivering smoother reverse, regenerative braking, stronger torque, and Bluetooth app control.
Choose your cart make/model, amperage (440A or 600A), and whether the kit includes the On-The-Fly programmer. Ideal for street and neighborhood use when you want a cost-effective DC controller upgrade without converting to AC.
