Details & Specs
Designed specifically for the Hard Korr Heavy Duty Battery Box, the Voltage-Sensitive Relay Kit from Hard Korr is perfect for creating a dual battery setup in your vehicle.
Manufactured using the highest quality materials, the inbuilt VSR acts as an isolator to allow the auxiliary battery to charge from the crank battery while your car is running.There’s no risk of draining your car battery either with the fully automatic operation cutting the link between the two batteries as soon as the ignition is switched off and the battery voltage drops below 12.7 volts.
Fitting neatly inside the Hard Korr battery box and with inbuilt surge protection, the Voltage-Sensitive Relay Kit from Hardkorr allows for a simple setup when you’re relying on battery power.
