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. Order online today and upgrade your electrical system with professional-grade wiring built to last.

Sun Bum kit a saver!!
Style: Mineral
Great little bag full of sunscreen for my grandson. Glad we had it to take it everywhere with us. A little pricey but he needs it so instead of taking bunches of bottles we had this.

Sunscreen is great, I would t recommend the chapstick
Style: Original
Sun Bum is hands down the best sunscreen I’ve ever used. It smells incredible, like a tropical vacation with that perfect coconut scent. It goes on smoothly, doesn’t leave you feeling sticky or greasy, and actually works! As long as I reapply every few hours, I don’t get burned, which is more than I can say for most other sunscreens I’ve tried. The face stick is good, goes on easily, but is a little greasy feeling. I do not like the chapstick, I can’t keep the taste of it out of my mouth and I feel like you have to put it on again and again.

Great Mineral Facial Sunscreen
Size: 1.7 Fl Oz (Pack of 1)
This is the best mineral facial sunscreen I’ve used. It comes out as a thin lotion that spreads easily. I have used two other brands and considered a brand that was expensive before trying this. I liked baby bum mineral 50 sunscreen lotion for the body and decided to give this a try. I like sun bum products. They tend to make effective products that are not too expensive. The zinc oxide mineral facial sunscreen I was using slightly irritated my skin and felt heavy like a mask after applying. It left a greasy residue on my face. This sun bum facial mineral sunscreen is non-irritating and feels very light like a chemical-based facial sunscreen. It leaves no residue on the skin. I prefer zinc oxide mineral sunscreen because it’s natural, safe and effective. Some zinc oxide mineral sunscreens put a white caste on the skin after application. The titanium dioxide and zinc oxide blended mineral sunscreens are worse due to the titanium dioxide. Titanium dioxide is a bright-white powdered substance, and I have not experienced any product with this ingredient that doesn’t appear white on the skin and cannot be blended. This sun bum zinc oxide mineral facial sunscreen has no white caste. Like another reviewer, I also hope that sun bum continues to make this facial mineral sunscreen indefinitely. It’s the best I’ve ever tried and at an excellent price point. If you like mineral sunscreens due to the health and environmental concerns with chemical-based sunscreens, try this before trying more expensive mineral facial sunscreens.
