2 AWG (35 mm²) Ultra-Flexible Tinned Copper Silicone Battery Cable

2 AWG (35 mm²) Ultra-Flexible Tinned Copper Silicone Battery Cable

This 2 AWG (35 mm²) silicone-insulated battery cable is a premium, high-current solution designed for demanding power applications where flexibility, heat resistance, and durability are critical. Constructed from approximately 6,700 ultra-fine strands of 0.08 mm tinned copper, it delivers exceptional conductivity while remaining incredibly flexible—often described as having a smooth, “noodle-like” feel.

The tinned copper conductor provides excellent resistance to corrosion and oxidation, making it well suited to marine, automotive, and off-grid environments. Encased in high-temperature silicone rubber insulation, the cable maintains flexibility in extreme cold and resists heat, vibration, abrasion, and environmental stress.

Rated to 600 V and capable of handling up to 200 A (depending on installation conditions), this cable is ideal for lithium battery systems, inverters, solar battery banks, high-power DC connections, car audio, welding equipment, and electric vehicle applications.
