Buyer's Guide
Lithium golf cart batteries: 1 pack, and what to ask before you order the carts
Our lithium golf carts run on a single LiFePO4 pack in place of the bank of lead-acid batteries under the seat. LiFePO4 is fitted as standard across our range rather than sold as an upgrade from a lead-acid base model; other lithium carts are built differently, so confirm the configuration rather than assuming. On the golf-cart platform the standard pack is 51.2V 105Ah — 5.376 kWh, charged by a 25A charger in roughly 4 to 5 hours, warranted for 3 years.
The 5 things to get on one line before you compare 2 quotes: the cell maker and cell grade, the BMS current rating, the cell count in series, the amp-hours, and the warranty term. The first 2 describe what is inside the pack and what it is built to handle; the last 3 describe its size and the commercial terms around it. Nominal voltage on its own decides nothing.

2 things to get in writing before you compare
Cell maker and cell grade
A LiFePO4 label tells you the chemistry. It does not tell you whose cells are inside or what grade they are, so 2 quotes can carry the same label and the same amp-hour rating and still not describe the same pack. Ask for the cell maker and the grade in writing.
BMS current rating
A quote may confirm that a battery management system is fitted without saying more. The numbers that describe what it is built to handle are its continuous current and its peak current. Ask for both figures rather than for the presence of the component.
Both are worked through in more detail, alongside the lead-acid comparison, in our detailed battery guide, which also runs the full lithium vs lead-acid comparison.
How much energy is in each pack?
Energy in kWh = volts × amp-hours ÷ 1000. It is the only figure that lets you compare a 48V pack against a 72V one, which is why amp-hours quoted on their own are a poor way to judge a quote.
| Pack | Energy | Where it sits | Charge time (est., charger as noted) |
|---|---|---|---|
| 51.2V 105Ah | 5.376 kWh | Standard on the golf-cart platform | ≈ 4.2 h at 25A |
| 51.2V 150Ah | 7.68 kWh | Upgrade option | ≈ 6 h at 25A |
| 51.2V 230Ah | 11.776 kWh | Maximum — fits the standard battery bay, quoted on request | ≈ 9.2 h at 25A |
| 73.6V 105Ah | 7.728 kWh | Part of the 72V drivetrain — motor, controller and DC-DC move with it, not a pack swap | ≈ 5.8 h at 18A |
The 230Ah maximum applies to the golf-cart platform, where the passenger models and the cargo-box build share one battery bay. It is not offered on the V-series electric utility vehicles. Other platforms, including the single-rider cart, are confirmed per inquiry rather than assumed from this row. We publish capacity rather than range for the upgrade packs: the mileage figures we hold are estimates made per seat configuration on flat ground, and quoting 1 number across every build would be inventing data we do not have.
How much is a lithium battery for a golf cart?
Size lithium golf cart battery quotes by energy rather than by amp-hours. Energy in kWh = volts × amp-hours ÷ 1000, so a 51.2V 105Ah pack is 5.376 kWh while a 73.6V 105Ah pack is 7.728 kWh — the same amp-hour number, with about 44% more nominal energy in the 73.6V pack. 2 quotes carrying the same amp-hour figure are therefore not necessarily offering the same thing, which is why amp-hours alone cannot rank them. We quote complete carts per configuration rather than publishing a battery price, so the pack is not a separable line you can divide out of our figure; amp-hours, system voltage and warranty term all move the cart price. Ask for cell count in series, amp-hours, warranty term, the cell maker and grade, and the BMS continuous and peak current on one line, and compare the energy each quote actually delivers before you compare anything else.
Lithium golf cart battery questions
How many batteries does a golf cart need with lithium?
On ours, 1. Our carts use a single integrated LiFePO4 pack where a lead-acid cart carries a bank of batteries wired in series under the seat. The pack is 1 unit with a battery management system fitted, so it is bought, warranted and replaced as 1 item rather than as a set. What that BMS is rated for is a question to put to any supplier: ask for its continuous and peak current. Other lithium carts are built differently, so confirm the configuration rather than assuming. On our golf-cart platform the standard pack is 51.2V 105Ah, documented to UN38.3 with an MSDS, and covered for 3 years. That pack is 5.376 kWh. Lead-acid remains available and is quoted on request, so the count under the seat is a configuration decision rather than something fixed by the chassis. Ask any supplier to state the configuration in writing rather than inferring it from the word lithium, because the word covers both arrangements.
How long do lithium golf cart batteries last?
Suppliers usually answer this with a cycle rating, and a cycle rating on its own is not something a fleet buyer can plan against, because it says nothing about the conditions it was measured under. Ask what those conditions were before you compare 2 of them. What you can pin down before ordering is the warranty. Ours is 3 years on the lithium pack, against 15 months on a lead-acid pack and 15 months on the vehicle. Ask any supplier for 3 things in writing: the warranty term, what it covers and what it excludes, and whether the cycle figure they quote was measured at full discharge or partial. A cycle count quoted without that condition cannot be compared against another supplier's, because the 2 may not be describing the same test. On our golf-cart platform the pack the warranty attaches to is the 51.2V 105Ah, 5.376 kWh unit.
How long does a lithium golf cart battery take to charge?
On the golf-cart platform we publish up to 5 hours for the standard 51.2V 105Ah pack on its 25A charger. Dividing amp-hours by charger amps gets you in the right area — 105 ÷ 25 is 4.2 — but treat it as a sizing check rather than the answer: real charge time depends on the state of charge you start from, and the charger's actual current profile. If an overnight window is not enough, that is a question to put to the supplier rather than something to solve by specifying a bigger pack — ask for the charger's amps and the conditions behind any published time. The 72V system runs a different charger again, at 18A, which is why a charge time quoted for one platform does not carry across to another even within a single supplier's range. Confirm which charger the quoted time belongs to.
Should you convert used stock to lithium, or stock carts that ship with it?
For a dealer this is an inventory question rather than a technical one, and the arithmetic usually settles it. A retrofit costs the pack, plus the labor, plus a charger with a LiFePO4 profile rather than a lead-acid one, and whether it affects the cart's existing warranty is a question for whoever wrote it. A cart that leaves our factory with LiFePO4 fitted arrives with a 3-year battery warranty and no retrofit labor for your shop. Our normal supply is the complete cart rather than the pack on its own. If conversions are what your market is actually asking for, say so when you inquire and we will tell you what we can and cannot do on that. Repeated conversion requests are worth reading as a demand signal about your floor stock. The technical points any conversion has to satisfy are the charger profile, a DC converter that carries the accessory load, and a pack that suits the bay and the weight it sits in.
What paperwork should come with a lithium golf cart battery?
A lithium pack carries its own documentation, worth checking before a first order rather than after. Ours carries a UN38.3 test summary and an MSDS, and the 2 do different jobs. The test summary records that the cells and the pack were tested to the transport standard, and it lists the model and its watt-hour rating. The MSDS describes the materials and how to handle them; it is not a substitute for the test summary. Ask any supplier for the UN38.3 summary covering the battery model they quoted, and check the model number on it against the model number on the quote: a summary can cover more than one model, so both have to match. The summary does carry a watt-hour rating and a model number, which is what makes the cross-check possible, but neither document speaks to cell grade or BMS rating — so treat both as a floor to clear rather than as evidence about how the pack will perform.
What size lithium pack does a golf cart need?
Size the pack by energy rather than by amp-hours. Energy in kWh = volts × amp-hours ÷ 1000, so our standard 51.2V 105Ah pack is 5.376 kWh. That formula is the only way to line up packs sitting on different system voltages, because amp-hours quoted on their own hide the voltage behind them. On the golf-cart platform the battery bay takes up to 51.2V 230Ah — 11.776 kWh — with no modification to the bay, and it is quoted on request rather than being a standard configurator option. Whether a fleet needs that depends on duty cycle and terrain rather than on seat count. We publish capacity rather than range for the upgrade packs: the mileage figures we hold are estimates made per seat configuration on flat ground, so quoting one number across every build would be inventing data.
Spec the pack against the market you sell into
Our normal supply is the complete cart. Tell us which market you sell into and how your customers use them — rounds or shifts a day, terrain, how long the charging window is — and we will size the pack against those numbers rather than quoting the largest one. LiFePO4 is the standard configuration across the range and carries a 3-year battery warranty; lead-acid is quoted on request under its own terms.
