Pre-made Leads

Pre-made Leads for Battery, Solar and Anderson Connections

Pre-made leads remove the cutting, stripping and crimping from DC wiring jobs. Each lead is built to a set length and cable size, so you can choose the run you need and fit it straight into a caravan, RV, 4WD, marine or off-grid power system. This collection covers three lead types: heavy-duty battery cables, twin solar extension cables and 50A Anderson style extension leads.

What's in the Range

• Positive and negative battery cable leads: 35mm², 50mm², 70mm² and 95mm² cable in 300mm, 600mm and 1000mm lengths. They suit battery-to-busbar, fuse, isolator and inverter connections.
• Battery parallel cable pairs: matched pairs in the same four cable sizes and three lengths. Use them to link batteries in parallel with equal-length interconnects.
• Twin solar extension cables: 4mm² and 6mm² twin cable in 1m, 3m, 5m and 10m lengths. They extend runs from roof-mounted or portable solar panels towards the charge controller.
• 50A Anderson style extension leads: 8B&S / 8AWG cable in 1m, 2m, 3m, 5m and 10m lengths. They extend portable solar, fridge and auxiliary power connections.

Choosing the Right Cable Size and Length

Cable size and length work together. A longer run or a higher current needs a larger cross-section to keep voltage drop and heat low. For high-current battery and inverter circuits, the 70mm² and 95mm² leads give more headroom than 35mm² or 50mm². For solar runs, 6mm² twin cable is the better choice over longer distances or higher panel currents, and 4mm² suits shorter runs and smaller arrays.

Choose the shortest lead that reaches comfortably. Extra length adds resistance, and excess cable coiled behind panels takes up space. If you are unsure which size your system needs, work through our DC cable sizing and system wiring calculator for RVs and caravans before ordering.

Why Use Pre-made Leads

Pre-made leads give consistent, repeatable connections without needing a heavy-duty crimper or lug tools on hand. Matched parallel pairs help batteries share current more evenly, and fixed-length solar and Anderson leads make it easy to plan and replace runs.

Compatibility Notes

Battery leads and parallel pairs suit 12V and 24V battery banks in caravans, motorhomes, boats, trucks and off-grid cabins. Before buying, check that the cable size matches your fuse rating, inverter current draw and terminal stud size. Solar extension cables suit portable and fixed panel installs. Make sure the panel's current sits comfortably within the cable's rating over the full run length. The 50A Anderson style leads suit 12V accessories, portable solar blankets and trailer or caravan auxiliary connections that use 50A Anderson style plugs.
