Once voltage drops below the threshold, the relay disconnects the batteries, ensuring your starter battery retains enough charge to start your vehicle. This 12V 140A unit also features an LCD display for real-time voltage monitoring of both batteries.\u003c\/p\u003e\n\u003ch4\u003eQ: What vehicles and applications is this dual battery isolator compatible with?\u003c\/h4\u003e\n\u003cp\u003eA: This 12V 140A Smart Dual Battery Isolator is designed for a wide range of 12V applications, including cars, trucks, caravans, RVs, boats, yachts, ATVs, UTVs, and off-road vehicles. Any 12V vehicle or vessel that uses a dual battery setup can benefit from this VSR isolator.\u003c\/p\u003e\n\u003ch4\u003eQ: Can I adjust the voltage thresholds on this isolator?\u003c\/h4\u003e\n\u003cp\u003eA: Yes. One of the key advantages of this smart isolator is its adjustable voltage settings. You can set custom engage and disengage voltage levels to match the specifications of your batteries and your unique usage requirements, giving you greater control over your dual battery system.\u003c\/p\u003e\n\u003ch4\u003eQ: How do I read the LCD display on this battery isolator?\u003c\/h4\u003e\n\u003cp\u003eA: The built-in LCD screen displays real-time voltage readings for both BATT1 and BATT2 simultaneously, with a monitoring range of 4.5V to 20V. This allows you to instantly check the status of both batteries without needing a separate voltmeter, making it easy to manage your vehicle's electrical system on the go.\u003c\/p\u003e\n\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"What does a Voltage Sensitive Relay (VSR) dual battery isolator do?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"A VSR dual battery isolator automatically connects a secondary (auxiliary) battery to the charging circuit when the primary battery reaches a set voltage threshold — typically indicating the alternator is charging.
