6 AWG Twin Battery Cable

6 AWG Duplex DC Power Cable – Red/Black Bonded (Sold by the Foot) A flexible, heavy-duty 6 AWG duplex (2-conductor) copper cable designed for clean and reliable DC power connections. Each conductor is color-coded red and black and bonded together, allowing you to run a tidy paired cable—or easily split it apart when separate routing is needed. Ideal for solar, battery, and inverter wiring where durability, flexibility, and simplicity matter. This is a go-to cable for building clean installs without dealing with loose conductors. Sold by the Foot — Double Value Each quantity ordered includes both conductors (red + black). You’re getting 2x 6 AWG cables in one bonded run—perfect for positive and negative in a single pull. Why You’ll Love It Clean installs – bonded red/black conductors keep wiring organized Peel-apart design – split the conductors easily when needed Flexible and durable – handles routing in tight spaces Oil, gas, UV, and abrasion resistant outer jacket Reliable copper conductors for consistent performance Made in Canada for dependable cold-weather use Perfect For This cable is ideal anywhere you need a matched positive and negative DC run: Solar charge controller → battery connections Battery → fuse block or busbar wiring Battery → small inverter connections (up to ~1000W on 12V systems, depending on length) 12V and 24V off-grid systems RV, van, marine, and mobile power installs Pro Tip Always fuse the positive conductor as close to the battery or busbar as possible. This protects the cable and your equipment in the event of a short circuit.

Always size wiring and protection devices appropriately for your system. Frequently Asked Is this sold as a single wire or a pair? This is a bonded 2-conductor cable. Each foot includes both a red and black 6 AWG conductor. For example, if you order a quantity of 5, you will receive 5 feet of red AND 5 feet of black in one bonded cable. Can I separate the two conductors? Yes. The cable can be easily peeled apart when you need to route the positive and negative separately near connection points. What size system is this suitable for? This cable is well suited for small to mid-size DC systems. On 12V systems, it is commonly used for loads up to around 1000W, depending on cable length and installation conditions. Is this suitable for a 48V system? It can be used on 48V systems for lower-current connections such as charge controllers or small loads. However, for high-power inverters or long runs, a larger cable size is typically recommended. Do I still need a fuse? Yes. Every connection to a battery should be protected by a properly sized fuse as close to the source as possible to protect wiring and equipment.
