Cushman golf carts typically require 48V battery systems for modern models, though legacy versions may use 36V configurations. Lithium iron phosphate (LiFePO4) batteries like 48V51.2V 80Ah or 100Ah units are optimal replacements, offering IP65 waterproofing, BMS protection, and 5-year warranties. Always verify voltage compatibility—using mismatched batteries risks damaging controllers or motors. LiFePO4 packs provide 6000+ cycles, doubling lead-acid lifespan while reducing weight by 40-60%.
How to Choose the Best Electric Golf Trolley for Your Game
How to select voltage for Cushman carts?
Identify existing battery voltage through cart manuals or existing pack labels. Most post-2000 Cushman models standardized on 48V systems for enhanced torque and range. Vintage models (pre-1990s) often used 36V configurations. Pro Tip: Use multimeter testing if labels are missing—measure battery terminals with cart switched off.
Why choose LiFePO4 over lead-acid?
LiFePO4 batteries deliver 6000 cycles vs 500-800 for lead-acid, with 95% usable capacity versus 50% in lead-acid. They maintain consistent voltage output even below 20% charge, preventing cart slowdowns. Real-world example: A 48V100Ah LiFePO4 pack weighs 45kg vs 115kg for equivalent lead-acid, reducing strain on cart frames.
| Parameter | LiFePO4 | Lead-Acid |
|---|---|---|
| Cycle Life | 6000+ | 500-800 |
| Weight (48V100Ah) | 45kg | 115kg |
| Charge Time | 3-4hrs | 8-10hrs |
What physical dimensions matter?
Battery tray measurements dictate compatibility—common Cushman tray sizes range from 1200×400×300mm (48V systems) to 800×350×250mm (36V). LiFePO4 packs like JRE-PK-4880GC use modular designs fitting OEM trays. Pro Tip: Create cardboard mockups of existing batteries to verify new units’ fit before purchasing.
How to ensure BMS compatibility?
Cushman’s 300-500A motor controllers require batteries with continuous discharge ratings (CDR) exceeding controller amperage. For example, a 500A controller needs batteries rated ≥600A CDR. Overspec by 20% to prevent voltage sag during hill climbs. Most quality LiFePO4 packs include 200A-1000A BMS options.
| Controller Amp | Min BMS Rating |
|---|---|
| 300A | 360A |
| 500A | 600A |

FAQs
Only with compatible motor/controller—voltage increases boost speed by 33% but may overload older wiring. Consult certified technicians before retrofitting.
Do lithium batteries work in cold weather?
LiFePO4 performs better than lead-acid at 0°C but charge below -10°C risks plating. Use heated battery blankets in sub-zero climates.
