Golf Cart Battery Solutions

Convert golf cart fleets from lead-acid to LiFePO4 with dedicated 36V, 48V and 72V single-pack replacements. This guide covers 36V, 48V and 72V system configurations, compatibility essentials, and wholesale/OEM supply options for dealers, fleet operators and cart converters.

How this page works: LJY Energy supplies dedicated LiFePO4 golf cart battery packs in 36V, 48V and 72V — single-pack lead-acid replacements matched to your cart voltage, coordinated through our manufacturing partners. Where a project requires it, we can also coordinate 12V LiFePO4 deep-cycle batteries wired in series to build 36V, 48V or 72V packs. Everything below covers both routes, starting with the dedicated packs we recommend first.

Why Golf Carts Are Switching to LiFePO4

Lead-acid batteries have powered golf carts for decades, but fleet operators are switching for measurable reasons:

  • 3–4× cycle life: A quality LiFePO4 battery delivers 3,000–4,000+ cycles at 80% depth of discharge, versus 300–500 cycles for flooded lead-acid at 50% DoD. One lithium set outlasts three to four lead-acid replacements.
  • Usable capacity: Lead-acid should not be discharged below ~50% without damage. LiFePO4 routinely uses 80–90% of rated capacity — a “100Ah” lithium battery delivers roughly twice the usable energy of a “100Ah” lead-acid battery.
  • Weight: LiFePO4 weighs about one-third of an equivalent lead-acid bank, improving hill-climbing and reducing turf wear.
  • Zero maintenance: No watering, no equalization charges, no terminal corrosion cleaning — meaningful labor savings across a fleet.
  • Faster charging: Lithium accepts higher charge currents and needs no absorption tail, cutting turnaround time between rounds.

For the full economic comparison, see our LiFePO4 vs lead-acid battery guide.

Golf Cart System Configurations

Most golf carts run 36V, 48V or 72V systems. The simplest conversion is a dedicated single-pack battery matched to your cart voltage (see Recommended Golf Cart Batteries below). A series string of 12V LiFePO4 batteries is another proven approach, configured as follows:

Cart voltage Configuration Example with 12V 100Ah Nominal energy
36V 3 × 12V in series (3S) 3 × 12V 100Ah ~3.84 kWh
48V (most common) 4 × 12V in series (4S) 4 × 12V 100Ah ~5.12 kWh
72V 6 × 12V in series (6S) 6 × 12V 100Ah ~7.68 kWh
BMS requirement: Each 12V battery has its own built-in BMS. In series strings, verify with your supplier that the BMS supports series operation at your string voltage, and confirm the maximum series count in writing before ordering. For most conversions, a single-pack battery with a purpose-built BMS avoids series-string balancing entirely — see our 48V 100Ah and 48V 150Ah golf cart batteries.

Recommended Golf Cart Batteries

Series-configuration options

Prefer to build a pack from 12V units, or working with a non-standard tray layout? The following 12V deep-cycle LiFePO4 batteries can be wired in series (3S / 4S / 6S) to build 36V, 48V or 72V packs, following the configurations and BMS notes above:

12V 100Ah Deep Cycle LiFePO4

1.28 kWh nominal · 100A BMS · 4,000+ cycles @ 80% DoD

The standard building block. Four in series make a 48V 100Ah (~5.12 kWh) cart pack.

12V 200Ah Deep Cycle LiFePO4

2.56 kWh nominal · extended range option

For extended-range carts or hilly courses. Four in series make 48V 200Ah (~10.24 kWh).

12V 300Ah LiFePO4 Battery

3.84 kWh nominal · maximum range

Maximum single-battery capacity for long-duty or commercial carts. Verify tray dimensions before ordering.

Installation & Compatibility

  • Physical fit: Measure your battery tray before ordering. 12V LiFePO4 batteries are often smaller than the lead-acid units they replace — use the supplied hold-downs or foam spacers to secure them.
  • Wiring: Use the same gauge or heavier cabling as the original installation. Keep series interconnects short and torqued to spec.
  • Charger: A LiFePO4-compatible charger (14.2–14.6V per 12V battery) is strongly recommended. Lead-acid chargers with desulfation/equalization pulses can trigger BMS protection. See our LiFePO4 charging guide.
  • Voltage display: Original “fuel gauges” calibrated for lead-acid voltage curves will read inaccurately. A shunt-based battery monitor is the reliable option.
  • Series BMS: Confirm series-operation support and maximum string voltage with the supplier in writing — see the note in the configuration table above.

Fleet Procurement & OEM

Frequently Asked Questions

Can I replace my 48V lead-acid set with four 12V LiFePO4 batteries?

Yes — this is the standard conversion. Four 12V 100Ah LiFePO4 batteries in series give a 48V 100Ah (~5.12 kWh nominal) pack. Confirm that each battery’s BMS supports series operation at 48V nominal, use a LiFePO4-compatible charger, and verify tray fit.

Do I need a special charger?

Strongly recommended. LiFePO4 charges at 14.2–14.6V per 12V battery with no equalization stage. Lead-acid chargers that apply desulfation pulses (15V+) can trip the BMS high-voltage protection. See our charging guide for details.

How many cycles will I get in golf cart duty?

Typical quality LiFePO4 delivers 3,000–4,000+ cycles at 80% depth of discharge under normal temperatures. Golf cart duty (partial daily discharge, moderate currents) is relatively gentle — many fleets see 5+ years of service. Actual life depends on depth of discharge, temperature and charge practices; see our cycle life vs DoD guide.

Will my existing battery meter work?

Probably not accurately. Lead-acid meters estimate charge from voltage, but LiFePO4 has a very flat discharge curve. A shunt-based battery monitor (measuring actual amp-hours in/out) is the reliable solution.

Can I mix old and new batteries in series?

No. All batteries in a series string should be the same model, capacity and age. Mixing degrades performance and can cause BMS conflicts. Replace the full set together.

Do you offer a complete 48V golf cart battery (single unit)?

Yes. Our catalog includes dedicated single-unit golf cart batteries — the 48V 100Ah and 48V 150Ah packs are direct lead-acid replacements, alongside 36V and 72V options (see Recommended Golf Cart Batteries above). A single pack means one BMS, no series interconnects and simpler installation than a multi-battery string. Contact us to match a pack to your cart model.

Can distributors source complete golf cart conversion kits?

A kit can be quoted per project: battery, a LiFePO4 charger, SOC meter, mounting parts and harness, matched to the cart models you serve. The kit content is fixed in the quotation.

Can golf cart batteries be supplied under our brand?

Yes. Private-label and OEM supply is coordinated per project. LJY Energy is a Shenzhen-based LiFePO4 battery supplier and OEM/ODM coordinator, not a factory. Production is carried out by partner manufacturers; the quotation names the producing manufacturer and the party that issues each document.

Which documents should a golf cart battery importer request?

Ask for the specification sheet with BMS continuous and peak current ratings, the UN38.3 test summary, the SDS/MSDS, and any test reports or certificates required in your market, plus the dangerous-goods shipping documents. Which documents exist for the exact model and destination is confirmed before you commit.

Are certifications available for golf cart batteries?

Certification and testing are available or arranged per project for the exact model, configuration and target market; certification and testing fees are borne by the buyer. No certificate is assumed to cover a model until the document for that exact model has been confirmed in writing.

How are golf cart batteries shipped from China?

LiFePO4 batteries ship as dangerous goods: UN3480, Class 9 (UN3481 when packed with or contained in equipment). The shipment needs a UN38.3 test summary, an SDS/MSDS, DG-compliant packaging and labels, and a dangerous-goods declaration; the route and forwarder are confirmed per order.
