Cobra Extra Flexible Marine Battery Cable | Tinned Copper Battery Wire For Boats (16mm²-50mm²) is a heavy-duty, single-conductor marine grade wire designed for battery circuits, charging systems, electrical panels, motor leads, and power connections. It belongs to the marine electrical cable and marine battery cable category and is manufactured with soft-drawn, Class K stranded tinned copper conductors. The fine-stranded construction provides the flexibility needed for routing cable through confined spaces, control cabinets, engine compartments, and other installations where rigid wire may be difficult to handle. Its tinned copper construction also helps protect the conductor against corrosion in moisture-prone electrical environments.

This Cobra marine battery cable uses flame-retardant polyvinyl chloride insulation with a VW-1 rating. The insulation is designed to resist moisture, abrasion, acid, diesel fuel and oil, making the cable suitable for demanding marine and electrical installations. It has a rated operating temperature of 105°C in dry conditions and 75°C in wet conditions, with a stated voltage rating of 600/1000 volts. The product is specified to UL 1426 and UL Listed BC-5W2 requirements. UL 1426 covers electrical cables intended for boats, including stranded copper boat cables with defined wet and dry temperature ratings.

The available conductor sizes are 16mm² or 6 AWG, 25mm² or 4 AWG, 35mm² or 2 AWG, and 50mm² or 1 AWG. Each size is supplied in red and black, allowing positive and negative battery connections to be identified clearly. The 16mm² cable is listed with 266 strands of 30 AWG wire, a nominal outside diameter of 0.342 inches, and a reference rating of 118 amps. The 25mm² version uses 420 × 30 stranding, has a nominal outside diameter of 0.386 inches, and is listed at 157 amps. The 35mm² cable uses 665 × 30 stranding, measures approximately 0.446 inches in outside diameter, and is listed at 213 amps. The largest 50mm² option uses 836 × 30 stranding, has a nominal outside diameter of 0.520 inches, and is listed at 246 amps. All listed options are supplied on 50-metre or 164-foot reels.

The extra flexible conductors meet ASTM B172, which covers rope-lay-stranded copper electrical conductors made with bunch-stranded members, including Class K constructions and conductors manufactured with tin-coated copper wire. This construction makes the cable suitable not only as a marine battery cable but also for battery charger connections, transformers, switchboard panels, electronic circuits, control systems, motor leads, and general power hook-up applications. The combination of flexible tinned copper, resistant PVC insulation, multiple conductor sizes, and red or black identification provides a practical cable option for professional boat wiring and other heavy-duty electrical work.
