Designed for complex mobile, marine, and off-grid power systems, this unit allows you to safely isolate high-current battery banks from a convenient, accessible location without routing heavy-gauge battery cables to your control panel.\u003c\/p\u003e\n\u003cp\u003eIn traditional setups, installing a manual battery isolator requires running thick, expensive cables from the battery compartment to a reachable switch location. This not only increases installation complexity and weight, but also introduces significant voltage drop and potential failure points. By placing the ePRO Remote Battery Switch directly in the engine room or battery compartment, you keep high-current cable runs as short as possible, operating the contactor remotely via thin signal wiring.\u003c\/p\u003e\n\n\u003ch3\u003eAdvanced Magnetic-Latching Technology\u003c\/h3\u003e\n\u003cp\u003eStandard solenoids and relays require a constant electrical current to keep their contacts closed, which creates heat and slowly drains your battery bank over time. In contrast, the Enerdrive ePRO utilises a bi-stable \u003cstrong\u003emagnetic-latching mechanism\u003c\/strong\u003e. It only draws power for a fraction of a second when changing states (opening or closing). Once engaged or disengaged, the internal magnets hold the contact in position with practically zero continuous current draw, preserving valuable stored energy in your 12V system.\u003c\/p\u003e\n\n\u003ch3\u003eKey Features and System Benefits\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e500A Continuous Current Rating:\u003c\/strong\u003e Built to handle substantial 12V DC loads, making it suitable for large inverters, bow thrusters, winches, and high-capacity house battery banks.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUltra-Low Power Consumption:\u003c\/strong\u003e Magnetic-latching design eliminates continuous holding current, preventing parasitic battery drain during storage or extended off-grid stays.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVersatile Remote Control Options:\u003c\/strong\u003e Operate seamlessly via a small panel-mounted switch, an external battery monitor (such as the Enerdrive ePRO Plus), or automated triggers from a Lithium Battery Management System (BMS).\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLocal Override and Diagnostics:\u003c\/strong\u003e Features a top-mounted interface with manual override buttons and status LEDs, allowing for direct control and system troubleshooting right at the battery bank.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProtected M10 Terminals:\u003c\/strong\u003e Heavy-duty M10 (approx. 3\/8\") stud terminals accommodate large battery lugs and are shielded by removable clear covers to prevent accidental short circuits.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRobust Mounting Design:\u003c\/strong\u003e Engineered with a flanged, pre-drilled base for secure installation inside engine bays, under-seat compartments, or dedicated electrical lockers.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eSeamless Integration with Lithium BMS and Battery Monitors\u003c\/h3\u003e\n\u003cp\u003eModern lithium battery setups require reliable protection against over-charge, over-discharge, and temperature extremes. The five-wire control harness on the ePRO Remote Battery Switch allows it to act as a primary safety disconnect controlled directly by a compatible external BMS or shunt-based battery monitor. If your monitoring system detects an out-of-bounds parameter, it can automatically trip the contactor to protect your valuable battery cells and downstream appliances from damage.\u003c\/p\u003e\n\n\u003ch3\u003eBuilt for Demanding Australian Conditions\u003c\/h3\u003e\n\u003cp\u003eWhether you are fitting out a touring 4WD canopy, upgrading a caravan electrical system, or wiring a marine vessel, electrical reliability is critical. Inferior switching mechanisms can suffer from welded contacts under high inrush currents or fail due to excessive heat build-up. The Enerdrive 500A contactor mitigates these risks through heavy-duty internal busbars and high-pressure contact points, ensuring minimal contact resistance and cool operation even under sustained loads.\u003c\/p\u003e\n\n\u003ch3\u003eUpgrade Your 12V Power Management\u003c\/h3\u003e\n\u003cp\u003eStreamline your high-current wiring and enhance the safety of your electrical setup.
