Best lithium golf cart batteries: 48V and 36V packs that fit

For most 48V carts, buy the Eco Battery 48V 105Ah kit made for your model, or the RoyPow 48V 105Ah to save a few hundred dollars. For a 36V cart you are keeping at 36V, the Dakota Lithium 36V 60Ah is the simplest swap. Before you order any lithium golf cart batteries, confirm the voltage: most brands here sell both a 48V and a 36V version, and the wrong one is a return. Six 8V or four 12V batteries under the seat means 48V; six 6V means 36V. If the batteries are already out, use the fitment finder with your make and model year.

This page is the overview. If you already know your voltage, the 48V lithium page and the 36V lithium page go deeper on each. The rest of the batteries hub assumes you have read this one.

What a lithium pack changes

Weight first. Six flooded 8V batteries weigh about 380 pounds. A 48V 105Ah lithium pack weighs 80 to 100. Take 300 pounds out of a cart and it accelerates harder, climbs better, stops shorter and the rear suspension sits up where it was designed to.

Voltage second. A flooded pack starts at about 51 volts and sags toward 46 as it discharges; the cart gets slower and weaker through the day. Lithium holds close to 51 until it is almost empty, then drops fast. You get the same cart from the first mile to the last, and you need the app or a meter to know when the last is coming.

Maintenance third. No water, no terminal corrosion, no sulfation if you leave it half charged for a month. You can store it at 50 percent all winter.

What does not change is the motor, the controller and the top speed. Lithium is not a speed upgrade. If that is what you are after, the faster-cart guide is the page.

Capacity: how many amp-hours you need

Amp-hours times volts is energy. A 48V 105Ah pack is about 5.4 kWh, of which you can use about 90 percent. At the 150 to 180 watt-hours per mile a typical cart uses, that is roughly 27 to 32 miles.

The flooded set it replaces, six 8V batteries at 170Ah, is 8.2 kWh on paper. But you should only use half of a flooded pack before recharging if you want it to last, so it delivers about 4 kWh usable, which is why a “smaller” lithium pack goes just as far.

Pick 105Ah if you drive around a community or a course. Pick 160Ah or more if you tow, live on steep ground, run a lifted cart on 23-inch tires, or regularly go 30 miles in a day. For 36V carts, 60Ah covers neighborhood use and 100Ah covers everything else.

The BMS rating matters more than the brand

Every lithium pack has a battery management system that cuts the output if current goes too high. The number to read is the continuous amp rating. A stock 48V cart with a 250 to 300A controller is happy with a 200A BMS because it rarely pulls that for more than a second. A cart with an aftermarket 400A or 500A controller, or a 36V resistor cart on the first speed notch, will trip a 200A BMS on hills. The premium packs carry 250A or more for exactly that reason.

Trays, cables and the charger

One lithium pack does not fill six battery slots. Every brand sells either a model-specific tray kit (Eco, Epoch) or a universal tray with brackets (RoyPow, Dakota), or avoids the problem by selling four 12V batteries that sit where the old ones were (Allied). The tray kit is the difference between a two-hour install and a Saturday of fabrication.

Reuse your main cables if they are 4 gauge or heavier and the ends are clean. If they are green, replace them; the battery cables page has sizes.

The charger has to be a lithium charger at your voltage with your cart’s plug. Most kits include one. If yours does not, or you want a second charger at the lake house, the charger guide lists lithium-compatible units by plug.

Which pack for your cart

Cart	Voltage	Pick	Why
Club Car Precedent, Onward, Tempo	48V	Eco Battery or Epoch kit	Model-specific trays; Precedent rear seat kits clear the pack
Club Car DS 1995 and later	48V	Eco Battery kit or Allied drop-in	DS tray is tall and flat; both fit without cutting
Club Car DS to 1994	36V	Dakota 36V 60Ah	Add a 150A-plus BMS for resistor carts
EZGO TXT 2010 and later (TXT48), RXV	48V	RoyPow or Eco Battery	RXV tray is shallow; check pack height before buying
EZGO TXT to 2009, Marathon, Medalist	36V	Dakota 36V	PowerWise plug; the included charger usually has it
Yamaha Drive, Drive2, G19, G22	48V	Eco Battery or Epoch	Yamaha trays are narrow; kits account for it
Yamaha G14, G16	36V	Dakota 36V	Confirm the charger receptacle type

Fitment pages for Club Car, EZGO and Yamaha have the serial-plate details if you are not sure which year you have.

Install: about two hours with a kit

Disconnect the charger. Photograph the old wiring before you touch it. Remove the old batteries with a strap and a friend; a flooded 8V is 63 pounds and the tray is awkward. Clean the tray, fit the new tray or brackets, set the pack, connect positive and negative to the same main cables the old pack used, and plug in the charger. Charge to full before the first drive so the BMS calibrates.

If the cart has a 12V accessory tap (lights, a stereo) running off two of the old batteries, it has nowhere to go now. Fit a voltage reducer from the full pack; the light kit guide explains that wiring.

When to stay with flooded

Low mileage and a warm garage. If the cart goes out a few times a month and lives on its charger, a good set of 8-volt or 6-volt flooded batteries will serve for five years at half the price, and the calculator will say so. Lithium is for carts that work.
