EZGO TXT Lithium Conversion: 36V and 48V Paths Compared
Applies to electric EZGO TXT models — 48V TXT48 (2010+) and 36V Series/DCS/PDS carts, whose path differs. Identify your system first if you haven't; the whole page keys off it.
Good news first: converting a TXT to lithium is simpler than the same job on a Club Car — no onboard computer to bypass, no charging-system surgery. Battery out, battery in, matched charger, done. The one strategic question is voltage, and it splits cleanly by which TXT you own.
TXT48 (2010+): the straightforward drop-in
Native 48V means the kit drops in: remove the lead set, install the lithium battery and hold-downs, connect, mount the included charger and state-of-charge gauge. An afternoon with hand tools, and the simplest conversion in this three-brand series.
36V TXT (Series, DCS, PDS): the fork
Two honest paths:
| 36V lithium drop-in | 48V system conversion + lithium | |
|---|---|---|
| What it is | A 36V-class lithium kit replaces the six 6V batteries — controller and motor stay stock | Controller, solenoid, and charger move to 48V spec alongside the lithium battery |
| Result | All of lithium's benefits — weight, zero maintenance, no sag, decade lifespan — at the cart's existing personality | The same benefits plus a genuinely quicker, stronger cart |
| Cost & scope | Battery swap, one afternoon | A project: components chosen together, best speced as a package from your serial |
| Right for | A cart you like as-is that just needs its last battery decision made | A cart you're upgrading anyway — pairs naturally with the motor and controller work in the TXT speed guide |
The wrong move is the one between the columns: putting 48V into a 36V cart without converting the components. The controller and solenoid are speced for 36V — this is a system decision, not a battery-only decision. Send the serial and we'll spec whichever column you choose, complete.
What changes
| Lead-acid | Lithium | |
|---|---|---|
| Weight | 300+ lbs | 70–130 lbs — a TXT is a light cart, and it feels it immediately |
| Maintenance | Watering, terminal cleaning | None |
| Charging | 8–10+ hours, full cycles | 3–5 hours, partial charges fine |
| Voltage under load | Sags — slower every hour | Flat to nearly empty |
| Winter | Trickle charge or sulfation | Store partial, walk away |
| Lifespan | 3–6 years | 3,000–5,000 cycles — the last battery decision |
The long-run math is in the lithium vs. lead-acid cost breakdown; on a TXT the short version is that the second lead-acid rebuy you skip pays for most of the kit.
Capacity
| Usage | Class | Realistic range |
|---|---|---|
| Golf and neighborhood loops | ~60Ah | 20–30 miles |
| Daily driver, rear seat, hills | ~105Ah | 35–50 miles |
| Lifted, big tires, heavy use | 150Ah+ | 50+ miles |
Why we lead with Bolt Energy kits: our house brand, stocked deep, supported directly, 12-year warranty. TXT kits ship with the matched charger, hold-down hardware, and a state-of-charge gauge — install it, because lithium's flat voltage curve makes old-style meters lie about range.
The install
Run/Tow to TOW (PDS/DCS) → lead-acid out — the workout is the whole job → clean the rack → set and secure the lithium battery → main connections → mount charger and gauge → RUN → drive. Videos on the installation hub and each kit's page. Retire the old PowerWise charger with the lead — the kit's lithium charger takes over, which also happens to end the PowerWise troubleshooting era of your ownership.
