Dual Battery Wiring Kits

Dual Battery Wiring Kit Overview

A dual battery wiring kit links your start battery and your aux battery so you can run 12V gear without risk to your main system. These wiring kits support fridges lights camp power and many other products you use on long trips. A complete dual battery wiring kit keeps your setup tidy and reduces voltage drop in tough conditions.

Battery wiring systems use cables fuses plugs and components that match the amp load of your dual battery system. Some kits provide plug and play dual battery wiring for fast install. Others use heavy cable for long runs across a 4WD caravan or camper. You can match each design to your solar controller DCDC charger or VSR unit.
