EZGO golf carts typically operate on 36-volt (36V) or 48-volt (48V) systems, with newer models and Lithium conversions sometimes utilizing 72V. 36V System: Commonly found in older EZGO TXT or Medalist models, usually using six 6V batteries. 48V System: Used in newer TXT, RXV, and Express models, often featuring four 12V or six 8V batteries. Lithium Systems: Available as 36V, 48V, or 72V, allowing for drop-in replacements. Always verify the voltage by checking your existing battery pack, the cart's motor, or the manufacturer's user manual, as using the wrong voltage can cause damage.
EZGO has used three primary voltage platforms over the decades. Knowing which system your cart uses is critical when replacing batteries, upgrading to lithium, or troubleshooting performance issues. Using the wrong voltage can damage the motor controller, reduce speed, or cause complete failure.
The 36V system is the oldest and most common on pre-2010 EZGO TXT, Medalist, and early RXV models. It consists of six 6-volt deep-cycle batteries connected in series. These carts are usually lighter-duty and were popular in golf courses and small communities. A full set of quality 6V batteries typically delivers good range for 2–3 rounds of golf but requires regular maintenance.
Since around 2010, EZGO has shifted most production to 48V systems. You will find these on newer TXT, RXV, Express, and L6 models. Configurations include six 8-volt batteries or four 12-volt batteries. The 48V system provides noticeably more power, better hill-climbing ability, and longer range than 36V carts. Most modern factory lithium ELiTE packages are 48V.
High-performance and lifted EZGO carts often run 72V systems (six 12V batteries). Many owners upgrade older 36V or 48V carts to lithium 72V packs for dramatically increased torque and range. Lithium conversions are available in 36V, 48V, and 72V configurations, allowing owners to choose the best balance of power and compatibility.
There are several easy ways to determine your cart’s voltage:
Count the batteries: 6 batteries = 36V (if 6V each) or 48V (if 8V each). 4 batteries usually means 48V (12V each).
Check the charger: The charger label will state “36V” or “48V”.
Look at the motor/controller: The controller housing or motor will have a voltage rating stamped on it.
Dashboard display: Newer RXV and Express models show the system voltage on the digital screen when powered on.
Data plate: The silver manufacturer plate under the seat or on the frame lists the original voltage.
If you are still unsure, count the number of cells or simply measure the total pack voltage with a multimeter after a full charge (36V pack ≈ 38–39V, 48V pack ≈ 50–52V).
For the best performance and longevity, upgrading to lithium is highly recommended. A quality lithium pack offers 3–5 times longer life, 2–3 hour charging, zero maintenance, and consistent power all day. Golf cart battery lithium solutions from Hydrocell are drop-in ready for most EZGO models and come with excellent warranties.
EZGO golf carts primarily use 36V and 48V battery systems, with 72V becoming popular for high-performance builds and lithium conversions. Knowing your exact voltage prevents costly mistakes when replacing or upgrading batteries. Whether you stay with traditional lead-acid or move to modern lithium, choosing the correct voltage and high-quality batteries ensures reliable performance and maximum enjoyment from your EZGO cart.
