Premium Australian Made Battery Bank Link Cables for Solar, Inverter & Off-Grid Power Systems
This listing includes one positive and one negative battery interconnect cable, each manufactured from Australian-made 35mm² (2 B&S) oxygen-free copper cable. Designed for connecting lithium, AGM, gel and lead-acid battery banks in series or parallel, these heavy-duty cables are hydraulically crimped, fitted with tin-plated copper lugs and sealed with adhesive heat shrink for maximum reliability.
What does 2 B&S mean?
2 B&S is the traditional Australian size designation for 35mm² battery cable. It refers to the cable's conductor size and current-carrying capacity, making it suitable for medium to high-current DC applications such as solar battery banks, caravans, 4WD dual battery systems, marine installations, inverters and off-grid power systems.
Our premium Solar Battery Interconnect Cables are designed for linking batteries in series or parallel across residential, commercial and off-grid battery storage systems. Manufactured using Australian-made 100% oxygen-free copper cable and fitted with heavy-duty tin-plated copper lugs, these cables provide maximum current transfer, low resistance and long-term reliability.
Each cable is professionally assembled in our Queensland workshop using hydraulic crimping and dual-wall adhesive heat shrink to provide a clean, durable and vibration-resistant connection. Whether you're installing a lithium battery bank, connecting batteries to an inverter or expanding your solar storage system, these cables are built to perform.
You will receive a Positive & Negative Pair of Cables – Includes one positive cable (red heat shrink) and one negative cable (black heat shrink). Ideal for connecting a completed battery bank to an inverter, charger, DC distribution system, or other high-current equipment in solar, caravan, marine, and off-grid installations.
35mm² (2 B&S) – 300mm Battery Interconnect Cable
This heavy-duty battery cable is designed to connect batteries together in series or parallel, or to connect a battery bank to an inverter, DC charger, busbar or other electrical equipment. Manufactured from Australian-made 100% oxygen-free copper, it delivers excellent conductivity with low voltage drop, making it ideal for lithium battery systems, solar installations, caravans, marine applications and off-grid power systems.
The 300mm length is perfect for linking batteries mounted side-by-side or close together, providing a neat, secure and efficient connection.
