EZGO (E-Z-GO) is one of the big three golf cart manufacturers, and its electric TXT and RXV models have a massive following with homeowners, courses and commercial fleets. Because both platforms started life on lead-acid power, today’s owners are increasingly converting to lithium — and that shift changes which EZGO golf cart parts wear out and need replacing. Here is what you should know about new-energy parts for EZGO TXT and RXV carts, from batteries to safety switches.
Why Lithium Is the Standard EZGO Upgrade
Lithium conversion kits simplify EZGO ownership in one word: maintenance. A LiFePO4 pack needs no watering, no corrosion cleaning and no terminal inspection, so owners genuinely can charge and drive. Two practical points matter more than anything else on EZGO carts: voltage matching (36V, 48V or 72V depending on your cart) and cycle life. Look for cells rated for 2,000 cycles or more so the conversion pays for itself over years of daily use.
10 EZGO Electric Parts Worth Knowing About
1. Lithium Battery Pack
The TXT and RXV are leaving 36V/48V lead-acid behind in favor of LiFePO4 lithium batteries. Buy a kit matched to your cart’s voltage with an integrated BMS, and verify the tray dimensions before ordering — a drop-in fit makes installation an afternoon job instead of a project.
2. Lithium Smart Charger
Most EZGO lithium conversion kits include a compatible smart charger, and for good reason: the charger must talk to the BMS with the correct multi-stage profile. If you need one separately, look for a dedicated lithium charger for your pack voltage.
3. Motor Controller
The controller is the core electronic component on every EZGO electric cart. RXV models typically run Danaher or Curtis controllers, while TXT carts most often use Curtis units. Controller failure is among the most common electrical issues on EZGO vehicles and usually shows up as a cart that will not run or that cuts out under load.
4. Speed Sensor
Speed sensor failure is a well-known EZGO RXV and TXT problem. The sensor reads motor RPM and reports back to the controller, so a failing unit causes sudden speed loss or an unresponsive pedal. On RXV carts with Danaher controllers built between 2008 and 2015, the OEM bearing encoder service kit (PN 612595) is the standard fix.
5. Forward/Reverse (F/R) Switch
On TXT models the F/R switch is one of the most frequently replaced parts of all. Heavy use wears the contacts until the cart drops out of gear or refuses to move. Light cases can sometimes be fixed with contact cleaning; badly worn switches need the complete assembly replaced.
6. Solenoid
EZGO solenoids (36V and 48V) are common replacement items. The giveaway symptom is a click when you press the pedal followed by nothing happening — the switch is closing but power is not reaching the motor, often due to pitted contacts or a weak coil.
7. Battery Cables
Cables carry full pack current from the battery to the motor, and they build up internal resistance as they age. Frayed, corroded or loose cables cause voltage drop, heat and even shorts. Inspect them whenever you service the batteries and replace any cable that looks worn.
8. Motor Brushes (Carbon Brushes)
Brushes are the wear items inside the motor itself. As they wear down, motor performance drops and eventually the cart can stop running altogether. Caught early, a brush replacement is one of the most practical repairs on an EZGO — and far cheaper than a new motor.
9. Battery Meter / SOC Gauge
After a lithium conversion, the old lead-acid voltmeter is not accurate enough to trust. Fit a dedicated SOC (State of Charge) gauge so you always know the real remaining range instead of guessing from voltage.
10. Run/Tow Switch
The Run/Tow switch is the EZGO safety switch that disconnects the high-voltage circuit. Always move it to Tow before any electrical work, and if the cart behaves erratically after servicing, check that the switch itself has not failed.
EZGO Maintenance Schedule at a Glance
- Weekly: check battery cable connections, test the lights
- Monthly: tire pressure and battery state of charge
- Every 6 months: inspect controller wiring, check the suspension
- Annually: full electrical inspection and carbon brush wear check
EZGO Solenoid Clicking But Not Moving? Try This
Hear the click but the cart stays still? Start with the battery voltage under load — a pack that drops hard under load points to batteries or cables. If voltage holds, test the solenoid contacts and then the controller inputs. On TXT carts also confirm the F/R switch is making clean contact. Working through those three steps resolves the majority of EZGO no-move complaints without replacing parts blindly.
