Buyer's Guide
Lithium vs lead-acid golf cart batteries
Lead-acid costs less to buy; LiFePO4 costs less to run. Flooded lead-acid needs its water topped up; LiFePO4 does not. Lithium generally tolerates being charged in short opportunity windows rather than needing one long cycle, and it is lighter for comparable nominal energy. Lead-acid still makes sense for a cart that runs a few times a month. The decision follows the duty cycle, not the chemistry.
The part that catches buyers out is that “48V lithium” is not one specification. A LiFePO4 cell is nominally 3.2V, so sixteen in series is 51.2V and fifteen is 48.0V. Both can be sold as 48V, and at the same amp-hour rating they are not the same amount of energy. Ask for the cell count and the amp-hours together.
What actually differs between the two
Where a row cites one of our figures it is our published specification; the rest are general characteristics of the two chemistries, not measurements of a specific pack. Nothing here is scored or ranked — a resort fleet and a buyer who uses a cart twice a month read the same row in opposite directions.
| Lead-acid | LiFePO4 (our standard) | |
|---|---|---|
| Purchase price | Lower | Higher |
| Routine maintenance | Flooded packs need water topped up and terminals cleaned; sealed AGM and gel do not | No watering; connections still worth inspecting |
| Partial charging | Left at partial charge for long periods without a full recharge, a flooded pack can sulfate | Generally tolerates short opportunity charges |
| Charge time | Depends on pack and charger; often planned as an overnight cycle | 105Ah ÷ 25A ≈ 4.2 h ideal estimate on our standard pack and charger (published: up to 5 h) |
| Weight | Heavier for comparable nominal energy | Lighter |
| Cold weather | Delivers less usable range in the cold | Also delivers less range in the cold, and the BMS may limit charging current |
| Our battery warranty | 15 months from factory ship date | 3 years from factory ship date |
| Export paperwork | Simpler | UN38.3 + MSDS + dangerous-goods certification |
Why two “48V lithium” carts can be different products
A LiFePO4 cell has a nominal voltage of 3.2V. A pack's real voltage is therefore the number of cells wired in series, multiplied by 3.2:
- 16 cells× 3.2V = 51.2V — the pack we fit
- 15 cells× 3.2V = 48.0V — also sold as 48V
Both are accurate descriptions of a 48V lithium pack. At the same amp-hour rating the 15-cell pack stores about 6% less energy ((51.2 − 48) ÷ 51.2 = 6.25%) — but amp-hours and cell count move independently, so a 15-cell pack with a higher amp-hour rating can hold more than a 16-cell pack with a lower one. Neither number means anything on its own.
The question to ask any supplier: how many cells in series, and how many amp-hours? Two numbers, and they let you compare any two carts on the same basis. Ours is 16 cells — a 51.2V 105Ah LiFePO4 pack as standard.
Two calculations that let you check any supplier
Neither needs a spec sheet you have to trust. Both work on any cart.
How much energy is actually in the pack?
kWh = volts × amp-hours ÷ 1000
- Our standard pack: 51.2 × 105 ÷ 1000 = 5.376 kWh
- Our 72V system: 73.6 × 105 ÷ 1000 = 7.728 kWh
Same amp-hours, about 44% more energy. This is why comparing carts on amp-hours alone is misleading — the voltage has to come with it.
How long will it really take to charge?
hours ≈ amp-hours ÷ charger amps
- Standard, 48V/25A charger: 105 ÷ 25 = 4.2 h
- 72V system, 18A charger: 105 ÷ 18 ≈ 5.8 h
This is an ideal current-based estimate, not a stopwatch figure: it ignores the starting state of charge, the taper at the end of a charge, and losses. Our published figures are up to 5 h and up to 6 h — part of that margin is temperature, because a battery-management system limits charging current when the pack is cold. A quoted time faster than this calculation is not necessarily wrong; it may reflect a higher-output charger or a partial-to-full window. Ask which inputs were used.
“Lithium” is not one chemistry
LiFePO4 — lithium iron phosphate. The more thermally stable of the common cathode chemistries, and what our published range uses.
NMC — the other cathode chemistry buyers meet, generally denser in energy per unit of size and weight.
Solid-state — not a third cathode chemistry. It describes the electrolyte and cell construction, and can be built around more than one chemistry.
If a spec sheet says only “lithium”, the chemistry is worth asking about before the order, not after.
What a lithium pack needs to actually ship
Three documents as a baseline:
- UN38.3 — transport testing
- MSDS — safety data sheet
- Dangerous-goods certification
Two details catch first-time importers. Batteries shipped separately from the vehicles also need packaging certification for small lithium batteries. Batteries shipped installed need the MSDS issued at vehicle level, not for the bare cell. Ask which version you are getting before the booking is made.
One wiring detail that bites after the order
The DC converter steps the pack voltage down to 12V for lights, mirrors and switches. On the 48V golf-cart platform it is 300W, sized for that load. Electric power steering draws about 175W on its own — so a cart on that platform specified with EPS needs the converter upgraded to 500W, or it runs overloaded. (The 72V four-wheel-drive configuration already ships with a 500W converter.) It is an easy thing to miss when options are added one at a time, and an awkward one to discover after a container has shipped.
Frequently asked questions
Is a lithium golf cart battery worth it over lead-acid?
For a cart that gets used most days — a rental fleet, a resort, a dealer demo — the argument for lithium is running cost rather than sticker price: no watering or equalising on a flooded pack, and it generally tolerates being charged in short windows between rounds rather than needing one long cycle. For a cart that runs a few times a month and sits on a charger the rest of the time, lead-acid's lower purchase price is harder to argue with. The answer depends on duty cycle, not on which chemistry is newer.
What does 48V actually mean on a lithium golf cart?
Less than buyers assume. A LiFePO4 cell has a nominal voltage of 3.2V, so a pack's nominal voltage is the cell count in series times 3.2. Sixteen cells in series is 51.2V, which is what we fit. Fifteen cells is 48.0V, which is also legitimately described as a 48V lithium pack. At the same amp-hour rating the 15-cell pack holds about 6% less energy — but a 15-cell pack with more amp-hours can hold more than a 16-cell one with fewer, which is exactly why voltage alone settles nothing. Ask any supplier for the cell count in series and the amp-hours together, not just the headline voltage.
How do you calculate a golf cart battery's real capacity?
Energy in kWh = volts x amp-hours / 1000. Our standard 51.2V 105Ah LiFePO4 pack is 51.2 x 105 / 1000 = 5.376 kWh. The 73.6V 105Ah pack on the 72V system is 73.6 x 105 / 1000 = 7.728 kWh — about 44% more energy from the same amp-hour number, which is why amp-hours alone are a poor way to compare two carts.
How long does a golf cart lithium battery take to charge?
Amp-hours divided by the charger's amps gives an ideal current-based estimate — it ignores the starting state of charge, the taper at the end of a charge, and losses. Our standard 105Ah pack with the onboard 48V/25A charger works out at 105 / 25 = 4.2 hours; the published figure is up to 5 hours. Part of that margin is temperature: a battery-management system will limit charging current when the pack is cold, so a winter charge can run nearer 4.5–4.8 hours. On the 72V system the charger is 18A, so 105 / 18 is about 5.8 hours against a published figure of up to 6.
Which lithium chemistry is used in golf carts?
Our published range uses LiFePO4 (lithium iron phosphate), the more thermally stable of the common cathode chemistries. NMC is the other one buyers meet; it is generally denser in energy per unit of size and weight. Solid-state is a different thing again — it describes the electrolyte and cell construction rather than the cathode, and can be built around more than one chemistry. The practical point: if a spec sheet says only "lithium", ask which chemistry before you order.
What documents does a lithium battery need to be exported?
Three as a baseline: UN38.3 transport testing, an MSDS, and dangerous-goods certification. Two details catch first-time importers out. If the batteries ship separately from the vehicles, the packaging carries its own additional certification requirement. If they ship installed in the vehicle, the MSDS has to be issued at vehicle level rather than as battery-only documentation. Ask which version you are being given before the booking is made, not after.
Can I still order lead-acid?
On the golf-cart platform, yes — its published battery specification lists lead-acid as an option alongside 150Ah and 73.6V packs. The single-rider cart has no lead-acid base model, and the electric UTV specifications list LiFePO4 only. Check the specification for the model you are quoting rather than assuming, and confirm it in the written quote. One commercial term does change with lead-acid: our lithium battery warranty runs 3 years from factory ship date, while lead-acid runs 15 months, the same as the vehicle.
