The VSR acts as an isolator, allowing the auxiliary battery (which is inside the box) to charge directly from the crank battery while the alternator is producing at least 13.2V, i.e. when the engine is running. When you turn off the ignition and the battery voltage drops below 12.8V, the VSR automatically cuts the link between the auxiliary and crank battery to prevent it from being over discharged.\u003c\/p\u003e\n\u003cp class=\"p1\"\u003eNOTE: This product is not suitable for vehicles with a variable-voltage alternator OR lithium batteries. Please check with your vehicle manufacturer prior to purchase if you think your vehicle may be equipped with a variable voltage alternator.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"Hardkorr","offers":[{"title":"Default Title","offer_id":42628269146284,"sku":"HAR-HKPBATTVSR","price":38.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0598\/1129\/9500\/files\/hardkorr-50a-12v-dual-battery-vsr-voltage-sensitive-relay.webp?v=1710995194","url":"https:\/\/roamgear.com.au\/products\/hardkorr-50a-12v-dual-battery-voltage-sensitive-relay","provider":"Roam Gear","version":"1.0","type":"link"}
