Range calculator
How far will your golf cart go on one charge?
Enter your battery the way it's sold — volts and amp-hours — or pick a kit. We estimate miles per charge, rounds of golf, the lead-acid comparison and the cost of a full charge.

How this calculator works
Range is usable energy divided by the energy your cart uses per mile. We start from about 95 watt-hours per mile for a two-seat cart on flat ground with stock tires, then add 15% for a four-seat body and 30% for a six-seat one, 8% per person beyond two, 18% for rolling and 38% for hilly terrain, 12% for 20–22" tires and 25% for 23"+ lifted carts. Lithium counts 90% of its capacity as usable, lead-acid 50%. A round of 18 holes is taken as about 6 miles.
These are our working assumptions, not manufacturer figures. For a 48V 105Ah pack in a two-seat cart they give about 51 miles — close to the 50 miles Epoch quotes for the same pack. Real range also depends on speed settings, wind, battery age and how hard you accelerate.
A worked example
A 48V (51.2V) 105Ah lithium pack stores 51.2 × 105 = 5,376 Wh. Using 90% gives 4,838 Wh. A four-seat cart with four people on rolling roads uses about 95 × 1.15 × 1.16 × 1.18 ≈ 150 Wh per mile, so the range is about 4,838 ÷ 150 ≈ 32 miles.
How to get more range
- Choose more amp-hours rather than a higher peak current — range comes from capacity.
- Keep tires at the recommended pressure; low or oversized tires cost miles.
- Avoid the highest speed setting on long trips.
- Don't charge a lithium pack below 32°F; most packs block it to protect the cells.
Questions people ask
How far will a 48V 100Ah lithium battery go in a golf cart?
About 40 to 50 miles on flat ground in a two-seat cart, by our estimate. Epoch's own estimator gives 50 miles for its 48V 105Ah pack in a two-seater. Hills, a six-seat body, extra passengers and lifted tires can cut that by a third or more.
Why does lithium go farther than lead-acid with the same amp-hours?
You can use about 90% of a lithium pack, but only about half of a lead-acid set before it starts to suffer. Lithium is also far lighter — owners report dropping around 250 lb — so the cart needs less energy per mile.
Is 100Ah enough for a golf cart?
For a two- or four-seat cart used for golf or around the neighborhood, usually yes. For six-seat carts, lifted carts with big tires, steep hills or long daily trips, look at 150Ah or more. Use our battery size calculator to check.
How much does it cost to charge a lithium golf cart?
A full charge of a 5 kWh pack uses about 6 kWh from the wall once charger losses are counted — roughly $1.10 at 18¢ per kWh, close to the 2026 US residential average. Enter your own electricity rate above.
Why is my real range lower than the box says?
Brand figures usually assume one driver on flat ground at moderate speed. Several Amazon reviewers report getting 30 miles where 50 was advertised. Passengers, hills, wind, speed settings and tire size all add up.
