Determining whether your EZGO golf cart operates on a 36V or 48V system is essential for safety, performance, and battery longevity. You can identify the voltage by inspecting the battery configuration, checking the charger specifications, or measuring the total voltage with a multimeter. Correct identification ensures optimal compatibility with Redway Battery replacements and prevents damage to your cart’s motor controller.
How Do I Identify My EZGO Golf Cart Battery Configuration?
The battery configuration defines the cart’s voltage. Most EZGO 36V models have six 6V batteries wired in series, while 48V systems use six 8V batteries or four 12V batteries. Older TXT models typically run 36V, whereas RXV models are more likely 48V.

-
Remove the seat or battery compartment cover.
-
Count the batteries and note individual voltages.
-
Use a multimeter: a fully charged 36V system reads ~38V, and a 48V system ~51V.
| Feature | 36V System | 48V System |
|---|---|---|
| Battery Voltage | 6V each | 8V each |
| Total Batteries | 6 | 6 |
| Charged Voltage | ~38V | ~51V |
⚠️ Always disconnect batteries before inspecting to avoid short circuits.
What Role Does the Charger Play in Voltage Identification?
Charger output voltage directly indicates the system type. A 36V charger delivers a maximum of ~42V, while a 48V charger reaches ~58V. Using mismatched chargers risks undercharging, overvoltage, or damage to the battery cells.

| Charger Feature | 36V System | 48V System |
|---|---|---|
| Max Voltage | 42V | 58V |
| Amperage Range | 15–25A | 10–18A |
| Compatible Batteries | 6x6V | 6x8V |
Always verify charger compatibility, and observe amperage if using analog chargers to protect battery life.
How Can I Use a Multimeter to Measure System Voltage?
Using a multimeter provides an accurate measurement of the total system voltage:
-
Set the multimeter to DC voltage.
-
Place the positive probe on the main positive terminal and the negative probe on the main negative terminal of the battery pack.
-
Read the voltage: ~38V indicates a 36V system, ~51V indicates a 48V system.
This method works even if labels are worn or missing.
How Do Battery Water Holes Indicate Voltage?
Counting the water fill holes on each battery offers a simple visual check:
-
Each hole represents 2 volts.
-
Six 6V batteries (3 holes each) equal a 36V system.
-
Six 8V batteries (4 holes each) or four 12V batteries (6 holes each) equal 48V.
This method is effective for lead-acid batteries and helps prevent misidentification when inspecting older EZGO carts.
What Insights Does Redway Battery Offer on Voltage Matching?
“Accurate voltage identification is critical for safety and performance. At Redway Battery, we recommend using lithium replacements, like our 48V 100Ah LiFePO4 packs, for upgraded torque and extended lifespan. Matching battery chemistry to your cart’s controller is essential—48V systems require MOSFETs rated for 60V+ to handle regenerative braking and avoid failures.”
Conclusion
Identifying whether your EZGO golf cart is 36V or 48V is crucial for proper operation and battery longevity. Inspect the battery configuration, verify charger output, and confirm with a multimeter. Redway Battery provides high-performance lithium replacements tailored to your voltage system, ensuring safer, more efficient operation and improved durability.
FAQs
Can I convert a 36V EZGO to 48V?
Yes, but it requires replacing batteries, upgrading the charger, and modifying the motor controller to handle higher voltage safely.
Does voltage affect speed?
Indirectly—48V systems maintain higher RPMs under load, allowing faster performance than 36V systems.
How many batteries power a 48V golf cart?
Typically six 8V batteries or four 12V batteries, connected in series for a total of 48V.
What is a fully charged 36V or 48V cart voltage?
A fully charged 36V cart reads ~38V, and a 48V cart reads ~51V after resting post-charge.
Where should I check my EZGO serial number for voltage info?
Look inside the passenger glove box, under the seat on the frame, or near the charger port; newer carts’ serials indicate voltage system.
Redway Battery ensures that your replacement batteries are fully compatible with both 36V and 48V systems, offering reliable energy solutions for every golf cart owner.
