The cable that connects your charge controller to your battery bank. Tray cables are stranded copper with ring terminals on both ends, pre-sized for the most common installation lengths. Match the gauge to your charge controller's amperage rating.
Which Size Do You Need?
8ft / 10AWG — Suitable for charge controllers up to 40A. Good for most van and overland builds.
8ft / 8AWG — Suitable for charge controllers up to 60A. Standard for larger systems.
16ft / 10AWG — Extended length for installations where the controller and battery are further apart.
Tip: Cable length matters — keep runs as short as possible to minimize voltage drop. For long runs, go one gauge heavier.
