4B&S (20.29mm²) Twin Core Automotive Cable per Metre

Heavy-Duty Twin Core Cable for High-Current 12V, 24V and 48V DC Applications

The 4 B&S (20.29mm²) Twin Core Automotive Cable is designed for demanding automotive, caravan, RV, marine, off-grid, industrial, and battery storage applications where reliable power delivery and simplified installation are essential. Featuring both positive and negative conductors within a single durable sheath, this premium twin core cable provides a neat, professional wiring solution for high-current DC systems.

Manufactured using high-conductivity oxygen-free annealed copper, this cable delivers excellent electrical efficiency with reduced voltage drop across longer cable runs. The flexible multi-strand construction allows for easier routing through vehicles, trailers, boats, and off-grid installations while maintaining the durability required for harsh operating environments.

Engineered for Reliable Power Transfer

Whether you're installing a dual battery system, powering a high-capacity inverter, connecting a DC-DC charger, or wiring a complete off-grid battery bank, this 20.29mm² twin core cable is built to handle substantial current loads. By incorporating both conductors into a single cable assembly, installation time is reduced while providing improved cable protection and a cleaner finished result.

The heavy-duty insulation is designed to withstand exposure to oil, fuel, abrasion, vibration, and demanding environmental conditions commonly encountered in automotive and marine applications. This makes it an ideal choice for professional installers and DIY enthusiasts seeking dependable long-term performance.

  • 20.29mm² (4 B&S) twin core cable for high-current applications
  • Oxygen-free annealed copper conductors for maximum conductivity
  • Flexible multi-strand construction for easy installation
  • Positive and negative conductors within a single protective sheath
  • Suitable for 12V, 24V and 48V DC electrical systems
  • Resistant to oil, fuel, abrasion, and harsh operating conditions

Reduce Voltage Drop in Critical Circuits

Voltage drop can significantly impact the performance of batteries, chargers, inverters, and other electrical equipment in low-voltage systems. The large 20.29mm² conductors help minimise power losses over long distances, making this cable an excellent choice for battery-to-battery charging systems, inverter installations, solar power systems, and auxiliary power circuits.

Using a quality twin core automotive cable not only improves system efficiency but also simplifies cable management by keeping both conductors protected within a single outer sheath. This reduces clutter, improves installation appearance, and provides additional mechanical protection compared to separate single-core cables.

Common Applications

  • Dual battery and battery management systems
  • DC-DC charger installations
  • Inverter power supply connections
  • Solar battery bank and charge controller wiring
  • Caravan, motorhome, and RV electrical systems
  • Marine battery and power distribution circuits
  • Off-grid solar and battery storage projects
  • Industrial low-voltage DC power applications

Installation Recommendations

For best results, ensure cable sizing is matched to the current demand and total cable run length of your system. Use quality crimp lugs, terminals, and appropriate circuit protection devices to maximise performance and safety. Protective conduit is recommended in areas subject to excessive abrasion or where cables pass through metal panels.

Build a Reliable Power System with Confidence

The 4 B&S (20.29mm²) Twin Core Automotive Cable per metre delivers the conductivity, durability, and flexibility required for modern high-current DC installations. Ideal for caravan, RV, marine, off-grid, industrial, 4WD, and battery storage applications, this premium twin core cable helps ensure efficient and dependable power delivery wherever your next project takes you.

Windshield wiper blades
Size: 24" + 19"(Pair for Front Windshield Lock)
Easy to install and fit perfectly on our 2023 Honda Civic sport. Good quality for a brand that is much cheaper than buying from the local auto parts store store. The last pair of these lasted a few years in the Florida sun so they are durable. The clean the windshield well and leave it streak free
