Electric Golf Cart (4-Seater, 48V / 72V Lithium)

LiFePO4 vs Lead-Acid: Total Cost of Ownership

A 48V 100Ah LiFePO4 pack costs approximately $400–600 more upfront than an equivalent VRLA lead-acid pack. The economics flip over a 3-year period: LiFePO4 delivers 2,000–3,000 charge cycles to 80% capacity vs 400–600 for lead-acid, and LiFePO4 maintains consistent performance across the entire discharge curve. Lead-acid carts noticeably slow down when the battery is below 50% charge. For golf course fleets operating two rounds per day, LiFePO4 payback period is typically 18–24 months.

Lead-acid carts require monthly water top-up, terminal cleaning, and equalization charging — labor costs that add up in a large fleet. LiFePO4 is maintenance-free. For resort and hotel applications where maintenance staff availability is limited, LiFePO4 is the practical choice despite higher initial cost. Verify the BMS includes cell balancing: without balancing, LiFePO4 cells drift in capacity over time and one weak cell limits the entire pack.

DOT Low-Speed Vehicle Requirements and Application Specifications

For road-legal operation on public roads in the US (including resort paths that cross public roads), golf carts must comply with FMVSS 500 (Federal Motor Vehicle Safety Standard for Low-Speed Vehicles) which covers headlights, taillights, turn signals, mirrors, and windshield. DOT requires this for maximum speeds of 40–45 km/h. Golf carts operating only on private property (golf courses, warehouse campuses) do not need DOT certification but may still need it for insurance purposes.

Golf course specification differs from warehouse specification: golf courses require a 250 kg payload capacity per ANSI/PGMS G1-1993, full suspension for turf protection (low tire pressure, >7-inch clearance), and quiet operation (below 60 dB at 7.5m). Warehouse application prioritizes payload (500–600 kg), flat floor clearance, and tight turning radius (<4m). Specify your application clearly before sampling — the differences in tire type, suspension, and body configuration are substantial.
