4 AWG Battery Cable Set (Pair)

Fleet Lithium 4 AWG Power & Ground Cable Set Purpose-built 4 AWG battery cables for standard-draw lithium systems — golf carts, LSVs, and utility vehicles running 36V–48V configurations. Electrical Specifications Conductor Size: 21mm² Fine-Strand Copper (4 AWG) Cable Length: 40 inches (3.3 ft) Insulation Rating: 200°C High-Temperature Jacket Resistance (40" run): ~0.00077 Ω Continuous Current Capacity: 135–170A (properly terminated) Surge / Burst Capacity: 300–400A (short duration) Lug Type: Heavy-Wall Tinned Copper Stud Compatibility: 10mm Performance Characteristics Low voltage drop under normal acceleration loads Sized for single-controller 36V–48V lithium setups Fine-strand flexibility for vibration resistance High thermal margin for lithium surge currents Optimized for short-run battery-to-controller connections When to Use 4 AWG vs 1/0 AWG 4 AWG cables are ideal for standard-draw systems pulling under 150A continuous. If your setup includes a high-output controller, dual motors, or peak draws above 300A, step up to our 1/0 AWG Cable Set for maximum headroom. Built to support the demands of modern lithium battery systems with stable voltage delivery under load.
