EZGO Golf Cart Battery
EZGO carts span 36V and 48V across three decades of models, so the first question is always which one you own.
This is the EZGO page of the golf cart battery set: pack voltages by model, charging behaviour, tray fitment and the replacement questions owners actually have.

Identify the cart before the pack
EZGO has built 36V and 48V carts for decades, and the pack layout does not follow the badge.
Older TXT and Marathon carts are 36V
Most older EZGO carts run six 6V blocks in a 36V string, with a charger that finishes near 44 to 45V. The common mistake is assuming a 48V charger will top one up because the cart 'looks newer than that'. Count the blocks and read the charger label before buying anything.
RXV and later 48V carts use four 12V blocks or six 8V
The 48V generation splits between four 12V blocks and six 8V blocks depending on model year. The tray is the tell: a four-block tray takes 12V, a six-block tray takes 8V. Getting this wrong means a return, because neither layout fits the other's hold-down.
The EZGO specifics that catch owners out
Two details on these carts cause most of the avoidable problems.
The 36V charger has a specific finish voltage
EZGO 36V chargers are built for six 6V blocks and finish in the 44 to 45V range with an equalise stage timed for flooded blocks. Fitting a generic 36V charger with a different profile shortens pack life, and a 48V unit will not start at all on a 36V cart.
Tray access and the replacement sequence
Several EZGO models need the battery compartment cover or seat removed to reach the rear blocks, and the hold-down bars come out in a set order. Doing the swap without that sequence is how people drop a block onto a cable or crack a case. Photograph the layout before removing anything.
The four facts you need before buying an EZGO pack
Model generation
TXT, RXV and the newer lithium-equipped carts have different voltages and tray layouts. The badge alone does not tell you the voltage.
Block count in the tray
Four blocks means 12V cells in a 48V cart; six blocks means either 6V in a 36V cart or 8V in a 48V one.
Charger finish voltage
The charger has to match both the pack voltage and the block chemistry. A mismatch is the most common cause of premature EZGO pack failure.
Whether the cart is a gas model
Gas EZGO carts need a small starting battery rather than a traction pack, and it is a completely different product.
Questions people ask before they buy
What kind of battery does an EZGO golf cart use?
Older TXT and Marathon models use six 6V blocks in a 36V string. The 48V generation splits between four 12V blocks and six 8V blocks depending on model year. Gas EZGO carts use a small starting battery instead, which is a completely different product.
How many volts is an EZGO golf cart?
Both 36V and 48V exist and the badge does not always tell you which. Count the blocks: six blocks means 36V if they are 6V, or 48V if they are 8V. Four blocks means 48V from 12V cells. Read the charger label as a cross-check.
What charger does an EZGO 36V cart need?
A 36V charger with a lead-acid profile for 18 cells, finishing around 44 to 45V at absorption with an equalise stage for flooded blocks. A generic 36V charger with a different profile will shorten pack life, and a 48V unit will not start on a 36V cart.
Can I replace six 6V batteries with three 12V batteries in an EZGO?
On a 36V cart, yes: three 12V blocks in series gives the same voltage, saves weight and needs fewer interconnects. The trade is shorter cycle life, because the same amp-hours sit in fewer, larger cells. Keep the amp-hour rating identical and make sure the charger profile matches.
Are lithium batteries available as a direct replacement for EZGO carts?
Yes, and they are widely used. A direct-replacement lithium pack is built to the cart's voltage with a tray footprint matching the original block layout, so the installation is a swap plus a charger change. Confirm the BMS current rating against your controller before ordering.
Send the model and we will confirm the pack
Tell us the EZGO model and year, the number of blocks in the tray and the charger label. We will confirm the voltage, recommend the pack and quote both a flooded set and a lithium replacement.
