Most golf carts sold in the last fifteen years run a 48V system, and if yours is one of them, you have more lithium options than anyone has time to research. The good news is that choosing well comes down to a handful of decisions, made in the right order. This guide walks through them the same way we do on the phone: capacity first, then the BMS, then charging, then installation, then price.
If you are still weighing whether lithium is worth it over another lead-acid set, start with our side-by-side comparison and come back. This guide assumes you have decided on lithium and want to pick the right pack.
First, confirm your cart is 48V
Two minutes with the battery compartment open settles it. Count the batteries and read the label on one of them. Six 8V batteries is a 48V system. Four 12V batteries is also 48V. Six 6V batteries is a 36V system, and you want our 36V options instead. Carts from Club Car, EZGO, Yamaha, Evolution and ICON built since roughly 2010 are predominantly 48V, but verify on your own cart before ordering anything.
Multiply the voltage printed on one battery by the number of batteries. The answer is your system voltage. 6 batteries x 8V = 48V.
Amp-hours decide your range
Capacity is sold in amp-hours (Ah), and amp-hours translate directly into how far the cart goes between charges. The right number depends on how you use the cart. A pack that only ever runs to the clubhouse and back does not need what a pack pulling a family around a 10,000-acre community needs.
| Capacity | Typical range | Right for |
|---|---|---|
| 60 to 80Ah | Roughly 20 to 30 miles | Neighborhood errands, 18 holes, single users |
| 100 to 110Ah | Roughly 30 to 45 miles | The mainstream choice. Daily community driving, 36 holes, two to four riders |
| 150Ah and up | Roughly 55 to 70 miles | Lifted carts, heavy passenger loads, hilly terrain, all-day use |
Range figures assume flat terrain and a stock cart. Hills, big tires, four adults and a cooler all pull the number down, so if your usage lives at the heavy end, size up a tier. Nobody has ever complained that the cart goes too far on a charge.
BMS ratings have to match your cart
Every lithium pack has a Battery Management System that limits how much current the pack will deliver. That limit has to exceed what your cart’s motor controller draws, or the pack will protect itself by shutting down under hard load, usually on the steepest hill you own.
Stock controllers in most 48V carts draw under 200A continuous, so a 200A-continuous pack covers them with margin. Upgraded controllers (common in lifted or modified carts) can draw 400A or more, and need a pack rated accordingly. If you are unsure what is in your cart, the controller’s model number is usually visible under the seat, and we can look up its rating when you call. For the longer story on what the BMS does, read What a BMS Does, in Plain English.
Chargers and charging
Your lead-acid charger does not move over to the new pack. Lithium uses a different charge profile, and charging a LiFePO4 pack with a lead-acid charger will either fail to fill it or trip the BMS repeatedly. Plan on a lithium-specific 48V charger, and prefer kits that include a matched one. The ECO 48V 105Ah kit, for example, ships with a matched smart charger in the box.
Charge times are a pleasant surprise coming from lead-acid. A 105Ah pack on a standard 25A charger fills from empty in 4 to 5 hours, and there is no harm in partial charges. Top up whenever it is convenient. Lithium has no memory and does not need to be run down before charging.
Installation basics
A quality 48V drop-in kit is a homeowner-grade project, not a shop job. The pack sits in the same tub your lead-acid set came out of, the included brackets take up the extra space, and the harness connects to your existing main cables. Plan on 30 to 60 minutes with hand tools, plus the satisfying part where you lift around 280 pounds of lead out, one battery at a time, and set one 72-pound pack in.
Two things to do before you start: photograph the existing cable routing, and order a kit whose hardware matches your cart make. Every product page on this site lists compatible makes and models in the Compatibility section, and if your cart is not listed, ask us before ordering rather than after.
What to spend
As of mid-2026, complete 48V lithium kits from established brands run from the low $2,000s for smaller capacities to the mid $3,000s for big packs. Within that band, here is what more money buys: more amp-hours first, then longer warranty, then features like Bluetooth monitoring and built-in heating for cold climates.
Our advice is unglamorous: buy the capacity your usage needs from a brand whose warranty you believe, and treat everything else as nice-to-have. A lifetime warranty from an established brand is worth more than an extra badge on the spec sheet. Be suspicious of packs priced far below the established brands. The savings usually live in the BMS and the cells, which are the two places you cannot afford them.
Common questions
Will one lithium pack really replace all six batteries?
Yes. One 48V LiFePO4 pack replaces the entire set. The kit includes brackets to secure it in the larger tray.
Do I need to modify my cart?
For the carts listed on a kit’s compatibility list, no. Drop-in means the pack fits the existing compartment and connects to the existing cables.
How long will a lithium pack last?
Quality LiFePO4 cells are rated for 3,500 or more cycles at 80% depth of discharge. At typical residential usage, expect the pack to be the last set of batteries that cart ever needs, and quite possibly to outlast the cart itself.
Is lithium safe in a golf cart?
LiFePO4 is the most thermally stable mainstream lithium chemistry, and it is the only one we sell for cart use. Add a BMS that disconnects on any fault, and the result is a system with fewer failure modes than the acid-filled batteries it replaces.
