Quick answer: An EZGO TXT lithium battery upgrade typically costs $2,200–$3,800 installed, adds 30–50+ miles of range per charge, and removes nearly all routine battery maintenance. For most 1996+ TXT owners, the strongest value is a 48V LiFePO4 bundle (105–160Ah) from a brand with a 5+ year warranty — we install Eco Battery, Allied, RELiON, and Dakota Lithium most often. Skip the upgrade only if your TXT is pre-1994 (early Series controller cars) or your motor and controller are already failing — lithium will not fix those.
Will lithium fit my EZGO TXT?
Almost any TXT built from 1994 onward can run lithium. The TXT platform has used several voltage/drive systems — 36V Series (DCS), 36V PDS, 48V PDS, and 48V ITS / Curtis — and modern lithium kits are sold for all of them. The only TXTs that are awkward to convert are the very early 1994–1995 36V Series resistor-coil cars, where you also have to budget for a Curtis or Alltrax controller swap to get the most out of a lithium pack.
To check what you have, look at the serial number plate under the glove box or seat. The two letters at the start of the serial encode the year and model. If you are not sure, send us a photo — or use our EZGO serial number decoder guide — as an Authorized EZGO Dealer we look up TXT serials every week.
Should I stay 36V or convert to 48V on my TXT?
If you own a 36V TXT (most pre-2008 cars), you have two paths:
- Drop-in 36V lithium bundle. Keep your existing 36V controller, motor, charger handle, and solenoid. Cheapest install, lowest disruption. Best for flat neighborhoods and stock-tire carts.
- 48V lithium conversion. Replace pack, controller, charger, and (sometimes) the motor. Roughly $1,000–$2,500 more, but you pick up real hill-climb torque, higher top speed, and better long-term parts availability. Worth it for lifted carts, hilly neighborhoods (Canyon Lake, Wildomar, Murrieta hills), and anyone planning a controller upgrade in the next year or two anyway.
In our shop, roughly 60% of 36V TXT owners stay at 36V on the first upgrade and 40% jump to 48V. If you have already lifted the cart or run 22"+ tires, we almost always steer you to 48V.
How much range will lithium add to my EZGO TXT?
Realistic per-charge range on a TXT depends on pack size, terrain, tire size, passenger load, and driving style. These are the numbers we see in the field:
| Pack | Voltage | Capacity | Realistic range (TXT) |
|---|---|---|---|
| 6× 6V flooded lead-acid (factory) | 36V | ~150Ah @ 20hr | 15–25 mi |
| 6× 8V flooded lead-acid (48V upgrade) | 48V | ~170Ah @ 20hr | 20–30 mi |
| LiFePO4 drop-in | 36V | 105Ah | 30–40 mi |
| LiFePO4 bundle | 48V | 105Ah | 40–55 mi |
| LiFePO4 long-range bundle | 48V | 160Ah | 60–80 mi |
Two things drive the lithium gap: lithium delivers nearly 100% of rated capacity regardless of discharge rate (lead-acid loses 30–40% under load), and a TXT lithium pack stays at full voltage until nearly empty — so you do not feel the cart sag at 60% state of charge the way you do on lead-acid.
Which lithium batteries fit an EZGO TXT?
We install four lines most often on the TXT. All are LiFePO4 (lithium iron phosphate) — safer chemistry than NMC, longer cycle life, much better high-heat tolerance for Southern California summers.
| Brand | Common pack | Warranty | Bluetooth/BMS | Notes |
|---|---|---|---|---|
| Eco Battery | 48V 105Ah / 160Ah | 8 yr | Yes (app) | Best balance of price + warranty for a TXT 48V conversion. Bundle includes charger. |
| Allied Lithium | 48V 105Ah / 160Ah | 8 yr | Yes (app) | OEM-direct fit kits, integrated heat dissipation. Strong for lifted TXT builds. |
| RELiON | InSight 48V 60Ah modular | 5–8 yr | Yes (CAN bus) | Modular — stack for capacity. Great if floor space is tight on early TXTs. |
| Dakota Lithium | 36V or 48V drop-ins | 11 yr | Optional | Industry-leading warranty. Good first-time lithium upgrade for stock 36V TXTs. |
| Trojan Trillium | 48V drop-in | 8 yr | Yes | Trojan-branded LiFePO4. Familiar name for owners coming off Trojan T-875 lead-acid. |
We keep the 36V Eco Lithium bundle and the 48V Eco Lithium bundle in stock for TXT installs because they ship with a matched charger and are the fastest swap on the platform — usually a half-day in the shop or driveway.

How much does an EZGO TXT lithium upgrade cost installed?
Pricing depends on whether you stay 36V or jump to 48V, and which brand pack you choose. From our shop in Canyon Lake (representative SoCal pricing):
| Upgrade | Parts | Install labor | Total installed |
|---|---|---|---|
| 36V drop-in lithium (105Ah) | $1,800–$2,400 | $300–$450 | $2,200–$2,800 |
| 48V lithium conversion (105Ah, with charger) | $2,200–$2,900 | $500–$800 | $2,800–$3,800 |
| 48V long-range lithium (160Ah, with charger) | $2,900–$3,800 | $500–$800 | $3,500–$4,600 |
| 48V lithium + Curtis/Alltrax controller | $2,900–$4,200 | $800–$1,200 | $3,900–$5,300 |
For comparison, a fresh set of 6× 8V flooded lead-acid Trojans on a 48V TXT runs about $1,200–$1,500 installed and lasts 4–6 years with disciplined watering. A LiFePO4 pack typically lasts 10–15 years and asks for nothing — no watering, no equalizing, no terminal corrosion brushing. Across the lifespan, lithium is usually the cheaper option, not the more expensive one.
What controller upgrades pair with EZGO TXT lithium?
A lithium pack on a stock TXT controller will run beautifully and feel quicker than lead-acid — but it will not give you a meaningful top-speed bump. To unlock real performance, pair lithium with one of these controllers:
- Curtis 1206 / 1510 (300A–500A) — the workhorse upgrade for 36V and 48V TXTs. Smooth ramp, programmable speed and acceleration, very reliable. See our Curtis controllers collection.
- Alltrax XCT / SR / NCX — programmable via cable, popular on 36V Series TXTs because the SR series is purpose-built for them.
- Navitas TSX 440A or TSX 600A — AC conversion option for 48V TXTs. Big torque, regen braking, but a more involved install.
The most common failure mode we see when owners DIY a lithium swap and skip the controller question is nuisance fault codes from voltage spikes the old controller cannot smooth out. If your TXT is a late-model 48V ITS car, you can usually keep the factory controller. On older PDS and Series cars, plan to upgrade.
For a deeper comparison, see our Navitas vs Curtis vs Alltrax controller guide and our golf cart controller upgrade cost & benefits breakdown.
What charger do I need for an EZGO TXT lithium conversion?
Lithium needs a lithium-profile charger — not a lead-acid charger. The factory Powerwise (36V) and Delta-Q (48V) chargers EZGO shipped with the TXT will charge a lithium pack but will not finish the cycle correctly, and over time they will damage the BMS. Three options we recommend:
- Bundled charger — Eco Battery, Allied, and Trojan Trillium kits include a matched lithium charger. Easiest path.
- Lester Summit II 650W or 1050W — programmable for any LiFePO4 chemistry, fast charge, premium build. Our preferred standalone lithium charger.
- Delta-Q IC650 or QuiQ-dCi — OE-quality, programmable lithium profile, ideal if you want it to look factory.

How long will a lithium battery last in my EZGO TXT?
A quality LiFePO4 pack rated for 3,000–5,000 cycles at 80% depth of discharge translates to roughly 10–15 years of typical TXT use (3–5 charge cycles per week). Across our 670+ five-star Google reviews, the most common feedback we hear from lithium converts is that they "forgot the batteries existed" — no watering, no equalizing, no winter slow-discharge surprises. The original lead-acid pack on most TXTs lasts 4–6 years and asks for monthly attention.
Heat is the one variable that matters in Southern California. LiFePO4 tolerates Coachella Valley summers far better than NMC chemistries, but you still want a pack with a BMS that throttles charging above ~125°F. Every brand on our recommended list does that.
Can I do an EZGO TXT lithium conversion myself?
If you are mechanically confident and your cart is a 36V drop-in scenario, yes — the install is a 3–5 hour job: disconnect, lift the seat, remove the lead-acid bank, mount the lithium tray, reconnect, install the new charger. Buy a torque wrench for terminal lugs and label every cable before you pull it.
For 48V conversions — especially those that involve adding a Curtis or Alltrax controller, swapping the solenoid, or rewiring the charger receptacle — we steer most owners to professional install. Mistakes on a 48V conversion can fry the new BMS, the new controller, or both. That single fault can erase all the savings of the DIY route.

What about warranty and resale value?
Two things to know:
- Pack warranty — LiFePO4 warranties run 5 to 11 years depending on brand. Most warranties require professional installation or photo documentation of a clean install. Our shop install paperwork satisfies every brand on our recommended list.
- Cart resale — A 4-year-old TXT with a documented lithium upgrade typically sells for $1,200–$2,000 more than the same cart with aging lead-acid. Buyers in retirement communities and second-home neighborhoods (Canyon Lake, La Quinta, Palm Desert) actively look for "lithium-converted" TXTs in classifieds.
The TXT is the most-produced golf cart in EZGO history. A well-maintained, lithium-converted TXT is one of the safest used-cart bets on the market.
Common EZGO TXT lithium upgrade mistakes to avoid
- Reusing the factory charger. It will run, but it will not finish the charge cycle correctly. Replace it.
- Mixing pack voltages. Do not run a 48V pack on a cart still wired 36V end-to-end. Either fully convert or stay 36V.
- Skipping the BMS Bluetooth pairing. If your pack has an app, pair it. You can catch a failing cell years before it strands you.
- Cutting OEM connectors. Use proper quick-disconnect lugs and protect the new run-and-tow / TOW switch wiring. Hacked harnesses void warranties.
- Ignoring the solenoid. A tired solenoid on a high-current lithium pack can weld closed under acceleration. Replace at install if it is original.
Frequently asked questions
Will lithium make my EZGO TXT faster?
By itself, lithium adds 1–3 mph and noticeably faster acceleration because the pack does not sag under load. For a real top-speed gain, add a Curtis or Alltrax controller and 22"+ tires.
Can I upgrade a 36V Series-controller TXT to lithium?
Yes, but plan to upgrade the controller too. The original Series resistor system fights lithium voltage curves and limits the gains.
How long does a lithium TXT take to charge?
Roughly 3–6 hours from 20% to 100% with a matched lithium charger, vs 8–12 hours on lead-acid. You can also stop a lithium charger mid-cycle without harming the pack.
Will a lithium pack run my factory accessories (lights, USB, fan)?
Yes — voltage stays in spec longer than lead-acid, so 12V accessories actually run cleaner. Use the existing voltage reducer or upgrade to a sealed DC-DC converter at the same time.
Is the EZGO TXT still being sold in 2026?
The TXT continues as a fleet/commercial product alongside the consumer-focused RXV and Liberty. Used TXTs from the 2000s and 2010s remain the most common cart we service in Southern California.
Can I finance a lithium upgrade?
Many of the brands we install offer financing. Ask us when you book and we will price two paths side by side — outright purchase vs financed.
Bottom line: is an EZGO TXT lithium upgrade worth it?
For most owners in Southern California, yes — on three measures:
- Range and torque — you immediately feel the difference, especially on hills and with passengers.
- Total cost of ownership — over 8–10 years, lithium typically lands cheaper than two cycles of lead-acid replacement plus the labor and watering time.
- Resale — documented lithium TXTs hold value better than lead-acid TXTs in our market.
If your TXT motor and controller are healthy, the upgrade pays for itself. If they are tired, plan a combined lithium + controller install — doing both at once saves labor and gives you a TXT that drives like a new cart.
