MINI 50A VOLTAGE SENSITIVE RELAY KIT (VSR)

The LEGENDS4X4 MINI 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.

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.

The VSR is basically an automatic isolator switch, that connects the circuit from the crank/starter battery directly to the auxiliary battery (inside the box) when the voltage reaches 13.2V, so that the auxiliary battery charges from the alternator while the car is running.

When the ignition is switched off and battery voltage drops below 12.8V, the VSR automatically isolates the auxiliary battery from the crank/starter battery so that you don’t risk flattening the starter battery.
