Short answer: A 48V golf cart can use several battery configurations. Common lead-acid setups include six 8V batteries or four 12V batteries, while many lithium conversions use one 48V-class LiFePO4 pack. The replacement must match the cart’s voltage, physical space, current demand, charger, and battery-management requirements.
Do not buy by voltage alone. A pack that says 48V can still be wrong if the case dimensions, terminal layout, peak-current capability, charger profile, or mounting method do not match your cart.

Common 48V battery configurations
- Six 8V lead-acid batteries: a traditional configuration used in many 48V carts.
- Four 12V deep-cycle batteries: another possible series configuration, depending on the cart.
- Single 48V lithium pack: common in conversions and newer lithium-equipped carts.
Do not mix old and new batteries in a series pack unless the battery manufacturer explicitly allows it. Age and capacity imbalance can make the whole pack perform poorly.
Current 48V lithium options worth comparing

TEMGO 48V 100Ah LiFePO4 battery
This is a single-pack lithium approach rather than a set of lead-acid batteries. Check the case size, terminal position, included accessories, and continuous/peak current ratings against your cart.
DC HOUSE 48V 100Ah lithium kit
This kit includes a charger, which can simplify a conversion, but the included charger still needs to be appropriate for the pack and your installation method.
LOSSIGY 48V 100Ah lithium battery
This is another 48V-class LiFePO4 option. Compare BMS output, case dimensions, monitoring features, and charger requirements rather than focusing only on amp-hours.
Lead-acid vs lithium
Lead-acid is familiar, widely serviceable, and often lower in upfront cost. Flooded packs require watering and ventilation. AGM reduces maintenance but still carries more weight than lithium.
Lithium can reduce weight, provide flatter voltage under load, and remove watering maintenance. The trade-off is that the pack, charger, BMS, and sometimes mounting hardware must work together correctly.
What to measure before ordering
- Battery tray length, width, and height.
- Terminal orientation and cable reach.
- Overall pack voltage.
- Charger connector and charging profile.
- Continuous and peak current requirements.
- Hold-down and mounting points.
Charger compatibility matters
A 48V charger is not automatically compatible with every 48V battery. Lead-acid and LiFePO4 packs use different charging profiles. Some lithium kits include their own charger; others require a separate compatible charger. Never assume an older lead-acid charger is acceptable for a lithium conversion.
Signs a 48V pack needs replacement
- Range has fallen significantly.
- The cart slows under load or on hills.
- One battery consistently reads lower than the others.
- The charger completes unusually quickly or runs far longer than normal.
- Lead-acid cases are swollen, leaking, or heavily corroded.
Frequently asked questions
How many batteries does a 48V golf cart use?
It depends on the configuration. Six 8V batteries and four 12V batteries are common lead-acid arrangements, while lithium conversions may use one integrated 48V-class pack.
Can I replace only one weak battery?
Technically possible in some lead-acid packs, but mixing ages and capacities can create imbalance. A complete matched set is often the better long-term solution.
Can I convert a 48V cart to lithium?
Many carts can be converted, but the battery, BMS, charger, mounting, and cable setup must suit the cart. Verify the conversion requirements for your model.
Bottom line
For a 48V golf cart, configuration is only the starting point. Match voltage, physical fit, current capability, charger profile, and installation hardware before choosing a replacement pack.
How capacity affects range
Amp-hour capacity matters, but it is not a direct promise of miles. Cart weight, tire size, speed, hills, passenger load, temperature, and battery age all change range. Compare usable capacity and current capability together, especially on lifted carts or carts with large tires.
Battery cables and connections
A new pack cannot perform well through loose, undersized, or corroded cables. Inspect cable ends, torque connections correctly, and replace heat-damaged cables before blaming the new battery for voltage drop.
