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.

Size: 7 Fl Oz (Pack of 1), Style: SPF 30
This is our go-to sunscreen. It has an 2020 EWG (ewg.org) safety rating of 3 (where a 1 is safest but often difficult to find and often too expensive and a 10 is the worst safety rating). We love that is not too thin or thick, so it goes on easily, and it works into your skin without leaving you white or greasy, has a neutral pleasant smell, stays on well in the water (up to 80 minutes), and is accessible (has a decent price around $1 per ounce and is easy to find in many local grocery and drug stores). It is the one my kids grab out of the pile every time! And the only reason there is a pile is that I am trying to find a sunscreen rated 1 or 2 by EWG that has all of the properties of Coppertone SPORT 30. The search continues....

Doesn’t come of from sweat or water
Size: 7 Fl Oz (Pack of 2), Style: SPF 30
The only sunscreen I use. Doesn’t burn eyes, doesn’t come off in the water or from sweat. Wish it came in SPF 20.

This sunscreen is well-known, but let me tell you about the manufacturer….
Size: 7 Fl Oz (Pack of 1), Style: SPF 30
Have been using this sunscreen for most of my life—it’s been around forever. Product consistency has always been 100 percent perfect. But a few weeks ago I purchased the sunscreen I’m reviewing here, and when I went to use it, rather than finding a well-blended white lotion, the lotion had separated into white clumps and a watery liquid. The product was clearly defective even though it was well within its use-by date. I reached out to Coppertone via email and asked for a product replacement. They got back to me that same afternoon with a letter of apology, sent me coupons for a few free bottles of this sunscreen, included some additional discount coupons for Coppertone products, and also sent a prepaid label and pouch to return the defective product since they wanted to make sure that they were able to solve whatever had led to that product being released in that condition. All in all, I was impressed. Coppertone is clearly a firm with a customer-centric culture, and a commitment to product quality. I thought I’d share this since it isn’t everyday that customers gets an inside look into the culture and values of an otherwise very well-known, market leading firm like Coppertone.

Perfect Travel Size TSA approved size
Size: 3 Fl Oz (Pack of 2), Style: SPF 50
I recently bought the Coppertone SPORT Sunscreen SPF 50 Lotion in travel size for my son’s first trip to Cancun alone, and I have to say, it was a fantastic choice! Whether you're headed to a sunny beach, a day of fishing, or just need reliable protection from the sun, this sunscreen delivers. Here’s my review based on its performance during the trip: Convenience and Travel-Friendly: The travel size is perfect for anyone on the go. It’s small enough to meet TSA guidelines for carry-ons, so you don’t have to worry about checking luggage or dealing with oversized bottles at security. My son was able to easily pack it in his carry-on without any hassle. Additionally, the compact size makes it super convenient to throw into a pocket or backpack for a day of fishing, beach trips, or any outdoor adventure. Sun Protection: The SPF 50 provides excellent protection from harmful UVA and UVB rays, which is especially important for long hours spent in the sun. Cancun’s sun can be intense, and my son was out in the elements for several hours each day (and I wasn't there to remind him to reapply sunscreen), whether he was fishing, swimming, or just relaxing at the beach. He didn’t get burned once!! As a mother of a redheaded 18 year old son I've spent the past 18 years of my life ensuring he wasn't scorched by the sun and Coppertone has yet to let us down! Water Resistance: The water-resistant formula is a huge plus, especially in places like Cancun, where you’ll likely be in and out of the water. My son spent plenty of time swimming and snorkeling, and the sunscreen stayed put. It lasted through sweating, splashing, and even sea water exposure without needing constant reapplication. It’s perfect for active outdoor activities, whether you're swimming, surfing, or just sweating it out in the sun. Mother approved!!
