Bought the Navitas controller for my EZGO, and it’s like night and day! The 600 Amp power is crazy good—my cart climbs hills smoothly now. Plus, the OTF (On-The-Fly) controller is a nice touch for adjusting speed. Quick delivery, too!

Awesome controller! My EZGO feels like a whole new cart. The torque increase is noticeable, and being able to adjust it with the OTF knob is super handy. Perfect for anyone needing more power on 36/48V carts.

I was expecting a bit more from the Navitas controller. It works fine, but the 600 Amp power didn’t make as much difference as I hoped on my 36V EZGO. Still, the OTF feature is convenient. Delivery took longer than expected, though.

The Navitas Controller for my EZGO Series cart has been a game-changer! I opted for the 600-amp version, and the power increase is noticeable right away. The throttle response is super smooth, and the included OTF (On-The-Fly) controller is a neat addition for adjusting performance on the go. Installation was straightforward, especially with the ITS compatibility. It’s honestly the best upgrade I’ve made. Highly recommend it if you’re looking to boost both speed and torque.

After installing this Navitas 36/48V controller, I noticed a big improvement in accelerationon my EZGO cart. super convenient, but I wish the instructions were a bit clearer. I had to watch a few YouTube videos to figure it out completely. Overall, it’s a solid upgrade, but for the price, better documentation would have been nice.

Very happy with this controller. The power boost is real, and the ability to adjust on the fly is awesome. I just wish it came with better mounting hardware – had to buy extra bolts for a secure fit. But now that it’s installed, I’m loving the improved performance and range. Definitely worth the investment if you want more control over your golf cart.

This controller works great with my 48V setup, and installation was straightforward. The OTF feature is handy, but I wish it had clearer instructions for tuning the settings. Still a good upgrade overall.

Shipping was fast, and the product arrived in perfect condition. The controller fit my 36V EZGO perfectly, but I had a bit of trouble with the wiring instructions. The adjustable OTF controls are a game-changer once it’s set up correctly.

The power boost from this 600 Amp controller is amazing! I can feel the extra torque immediately, especially on inclines. Switching between 36V and 48V setups was super easy with this unit. The only issue was a slight delay in shipping, but once it arrived, it was worth every penny. Best mod I’ve done on my EZGO by far.

Quick delivery and great customer support from Navitas. This controller gave my EZGO a significant performance boost, especially on hills where it used to struggle. The OTF programmer is easy to use and lets me dial in exactly what I need depending on how many passengers or gear I have. Installation was plug-and-play, just as advertised!

This Navitas controller is a beast! My 36-volt cart now feels much more responsive and gets up to speed faster. I was hesitant about the price, but after seeing the difference, it’s definitely worth it. My only complaint is that the OTF knob is a bit sensitive and takes some time to get used to. Other than that, it’s a solid product.

I upgraded from the stock controller, and what a difference! The 600 Amp model gave my cart a noticeable power boost, especially when hauling heavy loads. The OTF control is a nice touch, although I mostly leave it on one setting. Wish it came with better mounting instructions, but overall, I’m happy with the purchase.

Received this controller quickly and had it installed in no time. The jump in performance is night and day. I’m mostly running 36V, but the ability to switch to 48V with no issues is fantastic. The OTF is a great feature, though I’m still learning how to fine-tune it to get the perfect ride. Worth every penny if you want serious control over your golf cart.
