This plug-and-play dual battery wiring kit makes it easy to turn your Hard Korr Heavy Duty Battery Box into a dual battery setup. No DC-DC charger is required.

The Battery Box contains a Voltage-Sensitive Relay (VSR), which acts as an isolator. While the car is running (voltage >13.2V) the VSR links the auxiliary battery and the crank battery. When the ignition is switched off and the battery voltage drops below 12.7V, the VSR automatically cuts the link.

This kit contains everything you need to create your dual battery setup, including 6 metres of high-quality 8AWG cable and a 50A maxifuse.
