Caravans / RVs DC Cables & Accessories, Battery Monitors, Switches & Protection

Premium DC Cables, Battery Monitors & Wiring for Caravans

Build a safe, reliable 12V or 24V electrical system for your caravan, RV, 4WD, marine vessel, or off-grid tiny home. A robust power setup requires the right foundation: high-quality DC cables, accurate battery monitoring, and secure circuit protection. Whether you are wiring a new mobile build or upgrading an existing setup, our extensive range covers everything from heavy-duty copper lugs to smart shunts and tank level sensors.

High-Quality DC Cables, Conduit & Connectors

Wiring is the lifeblood of your off-grid system. We stock a comprehensive selection of single and twin-core automotive cable, flexible welding and battery cable, and UV-rated solar cable available by the metre or roll. To ensure a professional finish, protect your runs with split tube conduit and secure your roof penetrations with reliable Cable Entry Covers.

Make secure connections using genuine Anderson plugs, Stäubli MC4 connectors, and heavy-duty Exotronic copper lugs. When crimping, insulate and seal your terminals using our glue-lined Heat Shrink Tubing to prevent moisture ingress and vibration fatigue while on the road.

Advanced Battery Monitors & Tank Sensors

Never guess your state of charge again. Our range of Battery Monitoring Systems includes industry-leading Victron SmartShunts, Simarine Pico displays, and Enerdrive ePro monitors. These devices provide real-time data on voltage, current draw, and remaining capacity, so you can manage your power consumption with confidence.

Beyond power, keep track of your resources with smart sensors. We carry Ruuvi environmental sensors for accurate temperature monitoring, alongside Mopeka Bluetooth sensors and Enerdrive pressure senders for highly accurate water and LPG Tank Level Monitors.

DC Switches, Busbars & Circuit Protection

Safety and efficient power distribution are critical in commercial and recreational mobile applications. Consolidate your caravan wiring safely using high-amp Bus Bars and Studs from Blue Sea Systems, Victron, and Exotronic.

To isolate your batteries during storage or maintenance, install a robust Victron or Blue Sea battery switch. Complete your safety setup with appropriate Circuit Protection: Breakers, Fuses & Switches, including MRBF terminal fuses, MEGA fuses, and MIDI fuses, to protect your caravan RV cables and equipment against short circuits or overloads.

Essential Wiring Components for Mobile Upgrades

Our electrical selection ensures you have the exact accessories required for a safe, compliant installation:

• Power Distribution: Heavy-duty busbars and Lynx distribution systems for clean battery bank wiring.
• Cable Management: Waterproof Scanstrut vertical and horizontal cable seals to prevent roof leaks.
• Convenience Outlets: Fast-charging USB-C sockets and waterproof wireless chargers for device power.
• System Protection: Low voltage disconnects to prevent deep discharge battery damage.

Installation or Setup Considerations

When planning your caravan or RV electrical layout, correct cable sizing is crucial to minimise voltage drop, particularly on longer runs from solar panels or DC-DC chargers. Always match your wire gauge to the maximum continuous current of the circuit, and terminate connections using properly crimped copper lugs sealed with 3:1 dual-wall heat shrink. Position battery monitors, like the Victron SmartShunt or Simarine Pico, as close to the main negative battery terminal as possible to ensure all current is accurately measured. For roof penetrations, utilise UV-stable clamshells or Scanstrut cable seals to maintain a watertight barrier. Finally, install appropriate fuses as close to the battery source as practical to protect the entire cable run.
