Navitas 600-Amp 72V TAC2 AC Upgrade Controller Kit for EZGO TXT / S4 / L6 – Bluetooth + OTF

Push your 72-volt EZGO TXT, S4, or L6 to its limits with the Navitas 600-Amp 72V TAC2 AC Controller Kit. Purpose-built for lifted carts with large tires tackling hilly terrain — or any rider who wants to hit up to 25 mph on stock 18" tires. Plug-and-play installation uses your existing motor, solenoid, and wiring harness. The included On-The-Fly Programmer lets you tune speed, braking, and acceleration in real time, while Bluetooth connectivity turns your phone into a full vehicle instrument panel.

Also replaces the Curtis 1236-6404 in the Cushman Hauler.
