The Navitas 72V AC Controller has totally transformed my EZGO TXT! The power increase is noticeable, especially on inclines, and the Bluetooth feature makes adjusting settings on the fly super easy. The installation was straightforward, and the 440A/600A option is perfect for getting that extra torque. Highly recommend it if you want smoother rides and better control.

Super impressed by the performance boost this controller gives. My Express S4 now runs smoother and with way more torque. The Bluetooth tuning is a nice touch, although it took a bit of trial and error to get it dialed in. Only downside was a shipping delay, but the product itself is solid and worth every penny.

Wow, what a difference! My EZGO Express L6 went from sluggish to powerful with this Navitas 72V controller. The 600A setting really delivers when you need that extra push, and the app is super intuitive. Being able to monitor performance and tweak settings in real-time via Bluetooth is a game changer. Shipping was quick too.

Great upgrade for my Express S4! Installation was straightforward, but I did have to double-check the wiring. The app makes adjusting power on-the-go super convenient. My only complaint is that the shipping took longer than expected.

While the performance boost is noticeable, I had issues with the Bluetooth connectivity—it drops sometimes. It’s great once it’s working, but it can be frustrating. Wish there were more detailed instructions included.

Delivery took longer than expected, almost a week. I was hoping for quicker shipping. The controller itself is great, but the delay in shipping was frustrating. Navitas should work with a better shipping provider.
Tony B. –
The controller works well, but I had some trouble with the app connection at first. Once I got it working, it really enhanced the performance of my TXT cart. I’m not a tech expert, so maybe the issues were on me, but it would be nice if the instructions were a bit clearer. Overall, it’s a great upgrade if you’re looking for more power and control.

Definitely recommend if you’re serious about upgrading your cart.

The Bluetooth functionality is super convenient for tuning my Express S4, but it can be a bit laggy at times. That said, the performance increase is substantial. The 440A setting is great for everyday driving, while 600A is perfect for tackling hills. Instructions were easy to follow. Good product overall.

I’m not a tech guy, so the setup was a bit confusing for me. Once installed, it does what it says. I like the power boost but wish they had clearer instructions or videos. Bluetooth works okay, but there’s a slight delay sometimes.

Had high hopes for this controller, but FedEx lost my package. Thankfully, the seller quickly shipped a replacement. As for the controller, it’s a good upgrade for my L6, but I had some issues with lag in the Bluetooth connection. When it works, the power boost is great, but it was frustrating to set up.
Linda B. –
Solid controller with easy installation. The throttle response is sharp, and you can feel the extra torque. Bluetooth functionality is great, but the app layout could be better. Overall, a solid investment.

Upgraded my EZGO Express L6 to the Navitas 72V 600A controller and it’s an absolute beast now. Insane torque off the line, and the Bluetooth tuning is super intuitive with the Navitas app. Easily the best mod I’ve done—total game changer for hill climbs and towing.
Ben R. –
Anyone know if the Navitas 72V AC controller will work with a stock motor on the EZGO TXT? I’m eyeing the 440A version, but not sure if I need to upgrade the motor too. Really want the Bluetooth features and more speed without frying anything.
Jacob T. –
Installed the Navitas 440A 72V controller in my 2022 EZGO Express S4. Plug-and-play setup and the torque curve is super smooth. Bluetooth makes fine-tuning easy—adjusted throttle response and regen in minutes. Shipping from Prime Golf Parts was fast and on point!
