What Is A Golf Cart LiFePO4 Battery?
Golf Cart LiFePO4 Batteries are lithium iron phosphate power systems designed for electric golf carts, offering 48V-72V configurations with 50-150Ah capacities. These batteries provide 2000+ charge cycles, BMS protection against overcharge/overheating, and operate in -20°C–60°C temperatures. LiFePO4 chemistry ensures safer, longer-lasting performance compared to lead-acid, with 5-6 hour charging times and 20-50A discharge rates optimized for low-speed vehicles.
Sit-Down vs Stand-Up Forklifts
How do LiFePO4 batteries enhance golf cart performance?
LiFePO4 batteries upgrade golf carts with 3x longer lifespan than lead-acid (2000 vs 500 cycles) and 50% weight reduction. Their flat discharge curve maintains 48V-72V output until 90% depleted, ensuring consistent torque on hills. Pro Tip: Use low-temperature charging (-10°C cutoff) to prevent LiFePO4 capacity fade in winter operations.
Unlike lead-acid batteries that sag under load, LiFePO4 cells deliver stable voltage through advanced 23S cell configurations (for 72V systems). This allows golf carts to maintain 15-25 km/h speeds even with 4 passengers. Charging efficiency hits 98% with 58.4V/84V CC-CV protocols—a 30% time saving versus traditional chargers. For example, a 72V 105Ah pack from Dongguan suppliers provides 7.5kWh energy, enabling 8-hour runtime per charge. Warning: Never mix LiFePO4 with lead-acid in series—voltage mismatch triggers BMS lockouts.
| Parameter | LiFePO4 | Lead-Acid |
|---|---|---|
| Cycle Life | 2000+ | 500 |
| Weight (48V 100Ah) | 55kg | 130kg |
| Charge Time | 5h | 8h |
What voltage options exist for golf cart LiFePO4?
Common 48V/60V/72V systems match motor controllers’ input ranges. 48V packs use 16S LiFePO4 cells (51.2V nominal), while 72V requires 23S (73.6V). Higher voltages reduce current draw—a 72V 50Ah battery delivers same power as 48V 75Ah with 33% less heat buildup.
Voltage selection depends on cart design: 48V suits flat courses with 20A controllers, whereas 72V excels on hilly terrains needing 50A bursts. Pro Tip: Always verify controller max input—a 60V controller paired with 72V LiFePO4 risks MOSFET burnout. Many modern carts now adopt 51.2V (16S) as standard, balancing cost and performance. Did you know? Upgrading from 48V lead-acid to 72V LiFePO4 can increase hill-climbing ability by 40% without motor modifications.

FAQs
Yes in 90% of cases—ensure voltage matches and upgrade charger. 48V LiFePO4 works in 48V lead-acid slots but requires 58.4V cutoff chargers.
How to store LiFePO4 golf cart batteries winter?
Keep at 50% SOC in dry, 0°C–35°C areas. Perform 3-month balancing charges to prevent BMS drain.
