A lithium conversion replaces a cart's lead-acid pack with a lithium battery of the same nominal voltage, commonly 36 or 48 volts. Size amp-hours for the range you need, and make sure the battery's BMS continuous and peak current ratings exceed your motor controller's draw. You will need a lithium-compatible charger, and some carts, such as older Club Car Precedents with onboard computers, need a bypass. Look for UL listing.
Lithium has become the most popular golf cart upgrade. The conversion is straightforward if you match voltage, current and charging.
Find your voltage
| Lead-acid pack | Nominal voltage |
|---|---|
| Six 6 V batteries | 36 V |
| Six 8 V batteries | 48 V |
| Four 12 V batteries | 48 V |
| Six 12 V batteries | 72 V |
What to compare
| Spec | Why |
|---|---|
| Nominal voltage | Must match your system |
| Amp-hours (Ah) | Sets range; more for lifted carts, hills and passengers |
| BMS continuous and peak current | Must exceed controller draw, or the battery may cut out |
| Cell chemistry | LiFePO4 is the most common |
| Charger | Included, lithium-specific |
| State-of-charge display | Shows remaining range |
| Certification | UL 2271 or similar for light electric vehicle batteries |
| Warranty | Years and cycle terms |
Compatibility details
- Older Club Car Precedents with an onboard computer (OBC) usually need an OBC bypass.
- Upgraded high-amp controllers need a battery with a matching BMS.
- Plan for 12-volt accessories with a DC-DC converter rather than tapping individual batteries.
Range and lift kits
Larger tires and lifts increase energy use; see lift kits. Size amp-hours up if you plan both.

Common questions
Is lithium worth it for a golf cart?
Lithium is far lighter, needs no watering and usually lasts many more cycles than lead-acid, which often offsets the higher price over time.
What voltage is my golf cart?
Count the batteries and their voltage. Six 8-volt batteries make 48 volts; six 6-volt batteries make 36 volts.
Do I need a new charger for lithium?
Yes, or a charger with a lithium profile matched to your battery. Lead-acid chargers can damage lithium packs.
How many amp-hours do I need?
It depends on range, terrain, load and lift kits. More amp-hours give more range; check the maker's range estimates for your cart.
