What is a Navitas Controller?
The term “Navitas Controller” refers to the high‑performance motor controllers produced by Navitas Vehicle Systems, designed specifically for low‑speed electric vehicle (LSEV) platforms like golf cars. These controllers are engineered to manage the flow of current, enable regeneration, monitor system temperature and voltage, and provide a host of tuning options such as speed limits, regen strength and acceleration response.

Top Benefits You’ll Notice
Here are the major advantages you can expect when upgrading to a Navitas Controller:
- More power & torque – With higher current ratings (e.g., 440A or 600A) you get stronger torque from the motor, better hill‑climbing and quicker throttle response.
- Speed customization – These controllers let you set or adjust top speed, often via a Bluetooth‑enabled app or optional On‑The‑Fly (OTF) programmer.
- Regenerative braking & improved efficiency – Many Navitas controllers support regen in forward and reverse, boosting efficiency and offering smoother deceleration. Creative Cartz
- Better monitoring & control – The built‑in app/dashboard allows you to see battery voltage, motor/ controller temperature, gear indication (F/N/R), and even lock out features. BMC GOLF CARTS+1
- Plug‑and‑play or semi‑plug installations – For many major golf car models (e.g., Club Car, Yamaha, E‑Z‑GO), harnesses and conversion kits exist so the upgrade isn’t overly complex. Navitas Vehicle Systems+1
Overall, upgrading to a Navitas Controller is like giving your golf cart a new heart and brain: more muscle, smarter controls, and more adaptability.
Compatibility & Choosing the Right Model
Not all carts are built the same, so choosing the right version of the Navitas Controller and ensuring compatibility is critical.
- For example, the Navitas AC Controller for Yamaha Drive/Drive2 is offered in “440/600 A” versions and is designed for Yamaha G29/Drive2 models 2007‑Up. golfcartsworld.com
- The Club Car page lists DC to AC conversion kits and controllers in 440A and 600A variants for various models (Precedent, DS, Onward, Tempo) with harness details. Navitas Vehicle Systems
- For DC systems (versus AC), the TSX3.0 Controller line covers 36‑48 V systems in 440A/600A versions. Navitas Vehicle Systems
Key factors to check:
- Voltage of your system (e.g., 48 V, 72 V, etc)
- Motor type (AC vs DC induction vs separately excited)
- Harness compatibility (does a plug‑and‑play harness exist or will modifications be needed?)
- Solenoid, F&R (forward/reverse) unit & wiring gauge — upgrading a high‑power controller often means your wiring and other components must support the increased current! As one owner notes:
“I’m on my third year with the new controller … If I was in your shoes I’d want to upgrade the entire system to 48v…”
At Prime Golf Parts we can help you match the correct variant of the Navitas Controller for your make/model and ensure the supporting components are up to spec.
Installation Considerations & Best Practices
While the upgrade may look straightforward (“plug and play”) in many cases, you’ll improve outcomes and lifespan by paying attention to several details:
- Wiring & connectors – To handle 440A or 600A you’ll need cables of adequate gauge (often 2 AWG or larger), solid terminals and minimal resistance. One user reports smoking wires after pushing too hard:
“Any advice? … The cart has the original solenoid and we had smoking wires when doing 30+ MPH.”
Solenoid and F&R upgraded – Stock solenoids or F&R units may be undersized, particularly if you increase torque/speed.
- Motor condition – If your motor is old or not rated for the higher current/torque, it may become the limiting factor.
- Battery condition & capacity – Higher performance draws more current. Ensure your batteries are healthy, well‑maintained, and have appropriate capacity.
- Programming/tuning after installation – Use the app or OTF programmer to set correct voltage, speed limits, regen strength, motor characteristics. Many owners report needing to fine‑tune settings for hills or heavier loads. Reddit+1
- Thermal protection & mounting – Ensure the controller is mounted in a protected location with adequate ventilation or cooling, and that temperature limits are set within the app.
- Warranty & compliance – Some manufacturers void warranty if you significantly increase top speed or power beyond original spec. Be aware of local regulations if speed increases bring your cart into a different category.
Why Choose Prime Golf Parts for Your Navitas Controller Upgrade?
At Prime Golf Parts we specialize in golf car performance upgrades, and our offerings for the Navitas Controller reflect that experience. Here’s what sets us apart:

- We provide installation advice, wiring guidelines and tuning support to ensure you get the best results (and avoid pitfalls like overheating or wiring failure).
- We can assist with related upgrades (heavy duty solenoid, wiring kits, battery upgrades) so your whole system performs reliably.
- After‑sale support: since the Navitas Controller includes Bluetooth/ app functions, we can guide you through setup and parameter tuning to match your terrain, weight load and usage.
Real‑World Performance Gains & User Feedback
Users who have upgraded to a Navitas Controller report noticeable improvements. For instance:
“Replaced a factory controller with the 440A Navitas … 15 mph prior to upgrade now tops out around 42mph.” Reddit
“The cart took me from ~20mph to 25/26mph … I’ve had it to 36mph …” Reddit
These gains depend of course on battery, motor, terrain and load—so manage expectations accordingly. But the trend is clear: better torque, smoother throttle, higher top speed (if you permit it), and more overall responsiveness.
Summary & Recommendation
If you’re serious about taking your golf cart to the next level, the Navitas Controller is a smart investment. It offers significant improvements in power, flexibility, efficiency and control. However, success depends on choosing the right model for your cart, ensuring supporting hardware (wiring, solenoid, motor, batteries) is up to spec, and setting up the system properly.
Here are the key next steps:
- Verify your cart’s make, model, motor type (AC/DC), voltage and year
- Choose the appropriate Navitas Controller variant (e.g., 440A vs 600A; DC vs AC)
- Upgrade wiring/solenoid/F&R if needed
- Install and program parameters (speed, regen, voltage, temperature)
- Test under load (hills, typical number of passengers) and fine‑tune
- Monitor performance: battery voltage, temperature, current draw
