The Enerdrive 160A Dual Voltage-Sensitive Relay (VSR) is engineered to streamline charging in both 12V and 24V electrical architectures. By automatically detecting the system voltage, this battery isolator links your battery banks once the alternator brings the primary battery up to optimal charge levels, and isolates them when the engine stops or voltage drops. This ensures your dedicated starting reserve remains untouched while your auxiliary accessories draw solely from the secondary battery.\u003c\/p\u003e\u003ch3\u003eIntelligent Charging Protection and Low Standby Draw\u003c\/h3\u003e\u003cp\u003eUnlike manual isolator switches that rely on user intervention or standard solenoids that require complex ignition-feed wiring, a voltage-sensitive relay operates autonomously based on real-time electrical thresholds. In a 12V setup, the relay engages at 13.2V and disconnects at 12.8V (or 26.4V and 25.6V respectively in 24V systems). This prioritises the cranking battery first, reducing the risk of being stranded with a flat starter battery at a remote campsite or out on the water.\u003c\/p\u003e\u003cp\u003eAdditionally, the unit is designed with an ultra-low standby current of less than 3mA. This minimal parasitic draw prevents battery depletion when your vehicle, boat, or truck is placed in long-term storage, solving a common problem associated with lower-tier mechanical relays.\u003c\/p\u003e\u003ch3\u003eBuilt for Harsh Australian Environments\u003c\/h3\u003e\u003cp\u003eEngineered for demanding under-bonnet and marine installations, this 160A battery isolator features a fully encapsulated, IP67-rated enclosure. It offers robust protection against dust ingress, mud, high-pressure water spray, and temporary immersion. The heavy-duty stainless steel stud terminals are built to secure large-gauge battery cables without corroding in coastal or high-moisture environments, while the integrated mounting base ensures a vibration-resistant installation in rugged 4WD engine bays.\u003c\/p\u003e\u003ch3\u003eRemote Control and System Monitoring\u003c\/h3\u003e\u003cp\u003eWhile the VSR is designed for set-and-forget operation, it also incorporates dedicated ports for advanced system integration. An integrated remote on\/off connection allows you to wire an external override switch to manually control the relay when required. Furthermore, the status output port lets you connect a remote LED indicator directly to your dashboard or control panel, giving you clear visual confirmation of when your battery banks are linked and actively charging.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAutomatic 12V\/24V Detection:\u003c\/strong\u003e Seamlessly adapts to either 12V or 24V DC electrical systems without manual configuration.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh 160A Continuous Rating:\u003c\/strong\u003e Handles heavy charge currents from high-output alternators, making it suitable for large auxiliary battery banks.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIP67 Waterproof Housing:\u003c\/strong\u003e Fully sealed construction protects internal electronics against water, dust, and corrosive marine environments.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUltra-Low Standby Current:\u003c\/strong\u003e Consumes less than 3mA when idle to preserve battery capacity during extended storage periods.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRemote Monitoring and Override:\u003c\/strong\u003e Features connection points for an external on\/off control switch and a dashboard-mounted LED status indicator.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeavy-Duty Terminations:\u003c\/strong\u003e Equipped with corrosion-resistant stainless steel threaded studs for secure, low-resistance cable connections.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eIdeal Applications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e4WD and touring vehicles with under-bonnet or canopy dual battery setups\u003c\/li\u003e\n\u003cli\u003eMarine vessels requiring automated isolation between cranking and house batteries\u003c\/li\u003e\n\u003cli\u003e24V commercial trucks, buses, and heavy machinery\u003c\/li\u003e\n\u003cli\u003eCampervans and service bodies running high-draw 12V or 24V accessories\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eUpgrade Your Dual Battery System\u003c\/h3\u003e\u003cp\u003eSecure your starting power and automate your auxiliary charging with the Enerdrive 12V\/24V 160A VSR.
