Product Details

The Hardkorr battery box with voltage-sensitive relay (VSR) is a simple and effective way to set up a dual battery system in your vehicle.

The VSR acts as an isolator, allowing the auxiliary battery to charge directly from the crank battery while the alternator is producing at least 13.2V. This ensures that the auxiliary battery is charged whenever the engine is running. When the ignition is switched off and battery voltage drops below 12.7V, the VSR automatically cuts the link between the auxiliary and crank batteries to prevent the crank battery from being discharged.

The Hardkorr dual battery wiring kit makes it easy to install your dual battery setup as a DIY project. However, it's important to note that this VSR is not suitable for vehicles with a variable-voltage alternator. If you think your vehicle may have a variable-voltage alternator, please check with your vehicle manufacturer before purchasing.
