Buy Hard Korr HKPBATTVSR Voltage Sensitive Relay suit Battery Box online in Australia.
Using a battery box with voltage-sensitive relay (VSR) is the simplest way to create a dual battery setup in your vehicle. The VSR acts as an isolator, allowing the auxiliary battery (inside the box) to charge directly from the crank battery while the car 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. The optional wiring kit (SKU: HKPBATTWIR) makes it an easy DIY job to install your dual battery setup. KEY FEATURES Easy retrofit into Hardkorr battery boxes Fully automatic operation Inbuilt surge protection
