Anderson Extension Leads
Heavy-duty 50A Anderson plug extension leads in 1m to 10m lengths for 12V off-grid setups
Reliable Anderson Plug Extension Leads for 12V Off-Grid Systems
Setting up power for a caravan, 4WD, or camper trailer often requires moving your energy source away from the vehicle. Whether you are chasing the sun with portable solar panels or connecting a secondary battery box, our range of Anderson plug extension leads delivers safe and efficient power transfer. Designed to withstand harsh Australian conditions, these pre-crimped cables provide a plug-and-play solution for remote touring.
Minimise Voltage Drop with 8 B&S / 8 AWG Cable
When running 12V DC power over distance, maintaining steady voltage is critical for charging efficiency and appliance performance. Thin wires cause significant voltage drop, which can severely impact how well your deep cycle batteries charge. All Exotronic Anderson extension cables are manufactured using heavy-duty 8 B&S (8 AWG) twin-core wire. This robust thickness comfortably supports up to 50A of continuous current, making it highly effective for standard solar inputs and DC-DC charger applications.
By utilising premium copper conductors and ultra durable insulation, these leads remain flexible yet highly resilient against abrasion, heat, and moisture. They are an essential part of any reliable off-grid electrical kit.
Available Lengths for Every Application
Every campsite and vehicle layout is different, which is why we offer multiple cable lengths to suit your exact requirements. Choose from our curated selection to optimise your setup:
- 1m and 2m Anderson leads: Ideal for short connections between battery boxes, charge controllers, and nearby accessories inside a canopy or caravan boot.
- 3m and 5m Anderson extension cables: The perfect middle ground for reaching roof-mounted solar input ports from a portable blanket on the ground.
- 10m Anderson plug extension lead: Gives you maximum flexibility to park your camper or 4WD in the deep shade while placing your portable solar panels out in direct sunlight.
Seamless Compatibility
Fitted with industry-standard 50A Anderson style connectors, these cables are compatible with a vast array of off-grid equipment. The genderless design means you simply match the colours (usually grey to grey) to create a secure, vibration-resistant connection. For custom wiring modifications or repairing existing gear, you can also explore our range of individual Anderson plugs to match your new leads.
Frequently Asked Questions
Will a 10m Anderson extension lead cause voltage drop?
Any extension cable will introduce some voltage drop, but the impact depends on the cable thickness and the current flowing through it. Our 10m Anderson leads use thick 8 B&S (8 AWG) wire, which keeps voltage drop to a highly acceptable level for standard 12V portable solar blankets and 50A accessories. If you are pushing maximum current over extremely long distances, you may need a custom thicker cable, but for typical camping setups, 8 B&S is the standard recommendation.
Can I join two Anderson extension cables together?
Yes, because 50A Anderson style plugs are genderless, you can easily plug two extension leads into each other to create a longer run. However, keep in mind that every connection point introduces a tiny amount of resistance, and increasing the total length will increase voltage drop. It is always better to use a single 10m cable rather than daisy-chaining two 5m cables if you frequently need the extra reach.
Are these leads suitable for marine or external use?
While the heavy-duty insulation is designed to handle outdoor conditions, dirt, and light moisture, standard Anderson style plugs are not fully waterproof. If you are permanently mounting connections on the outside of a boat or caravan, consider using protective covers or routing the connections inside a weatherproof enclosure.
