Ready for Dual Battrery Setup

By using the optional Voltage Sensitive Relay (VSR) available for our battery box (part no. HKBATTVSR), you can charge your auxiliary battery from your crank battery while the vehicle’s engine is on.

The optional VSR fits neatly into the lid of the box with no cutting or soldering. It acts as an isolator, allowing the auxiliary battery (inside the box) to charge directly from the crank battery while the car is running (voltage >13.2V). When the ignition is switched off and battery voltage drops below 12.7V, the VSR automatically cuts the link between the batteries.

We also offer an optional wiring kit (HKPBATTWIR), which makes it an easy DIY job to install your dual battery setup.

Please note: The optional VSR may not be suitable for some modern vehicles which are fitted with a Variable Voltage Alternator.
