How Many Lithium Batteries for a 48V Golf Cart?
It depends on the module voltage: one 51.2V unit, or four 12V lithium batteries in series. Here is how to choose the configuration and the capacity that matches your range goals.
Quick answer: The number of lithium batteries for a 48v golf cart depends on the module voltage. The two common setups are: (1) a single 51.2V lithium battery — one all-in-one unit that drops in and is the simplest option; or (2) four 12V lithium batteries wired in series (12 x 4 = 48V nominal). Some packs use other arrangements, but one 51.2V unit or four 12V units are by far the most common. After voltage, choose capacity (amp-hours) to match your range needs — 100Ah is a popular all-around choice.
01 // Option 1: One 51.2V Unit
The simplest path is a single 51.2V (48V nominal) lithium battery — one box, one BMS, minimal wiring. It drops into the battery compartment and connects to the existing main cables. This is the cleanest install and the most common modern choice. Remember that 51.2V is just the precise lithium label for a 48V system — see our 48V vs 51.2V explainer.
02 // Option 2: Four 12V Lithium Batteries for a 48V Golf Cart
The other common setup is four 12V lithium batteries wired in series to make 48V nominal. This mirrors a familiar lead-acid layout and can be easier to fit in some trays. Each module has its own BMS, or they share a system. Wiring is the same series principle as four 12V batteries in a 48V cart.
03 // Choosing Capacity (Amp-Hours)
Once voltage is set, capacity decides range. A 100Ah pack is a strong all-rounder; larger amp-hour packs go farther but cost and weigh more. Match capacity to how far you drive on a charge — see realistic numbers in our 48V range guide.
04 // Install Considerations
Whichever count you choose, you need a lithium-profile charger and possibly an OBC bypass on Club Cars. Confirm tray dimensions and secure mounting. For the full procedure, see how to connect a lithium battery to a golf cart.
Lithium Count Summary
For lithium batteries for a 48v golf cart, use one 51.2V all-in-one unit or four 12V lithium batteries in series. Then pick capacity (100Ah is a great all-rounder) to match your range, and use a lithium charger.
