Hardkorr Voltage Sensitive Relay VSR Kit for HardKorr Battery Box

Description:

Using a Hardkorr 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 alternator is producing at least 13.2V (i.e. 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.

Our optional dual battery wiring kit makes it an easy DIY job to install your dual battery setup.

This Voltage-Sensitive Relay can also be used in 12v setups without a Hardkorr battery box.

PLEASE NOTE: this product is not suitable for vehicles with a variable-voltage alternator. Please check with your vehicle manufacturer prior to purchase if you think your vehicle may be equipped with a variable voltage alternator.

DEEP CYCLE BATTERIES

Deep cycle batteries, sometimes also referred to as deep cell batteries, are designed to be deeply discharged on a regular basis. In contrast to starter batteries, which are designed to be constantly topped up and deliver short, high-current bursts of power, a deep cycle battery is designed to deliver sustained, lower-current power over a long period of time.

BATTERY BOXES

Our heavy duty battery box allows you to turn a regular deep-cycle battery into a convenient portable power station, or create a dual-battery setup using the optional VSR. It is suitable for all deep-cycle batteries up to 330mm (l) x 180mm (w) x 240mm (h) in size.

12V TO 240V INVERTERS

Running your 240V appliances while on the road has never been easier. Built to power appliances like your LED TVs, laptop chargers, and pedestal fans, Hardkorr's inverter is the perfect solution for those still wanting to enjoy a few luxuries while travelling in their caravan, camper, or 4x4 setup.
