In standard installations, the remote on\/off circuit references the primary battery (such as a starter battery). This cable solves the challenge when the remote signal must originate from the secondary battery—common in \u003cstrong\u003elithium battery systems\u003c\/strong\u003e where the BMS controls charging. By providing electrical isolation, it ensures safe, accurate signalling without ground loop interference or voltage mismatch.\u003c\/p\u003e\n\u003ch3\u003eHow It Works\u003c\/h3\u003e\n\u003cp\u003eInside the cable’s encapsulated inline junction, an \u003cstrong\u003eopto-isolator circuit\u003c\/strong\u003e separates the primary and secondary battery references. When the BMS sends a pull-down signal (as low as approximately 4 V), the cable translates it to the charger’s remote input, enabling or disabling charging precisely when needed. This protects your \u003cstrong\u003elithium battery bank\u003c\/strong\u003e from overcharging or operating outside safe parameters, extending battery life and system reliability.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eElectrical isolation\u003c\/strong\u003e between primary and secondary battery references prevents ground loops and voltage conflicts\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePre-crimped wire ferrules\u003c\/strong\u003e for quick, secure connection to the Orion-Tr remote terminal and BMS control ports\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEncapsulated inline junction\u003c\/strong\u003e resists moisture and vibration, suitable for engine bays and harsh mobile environments\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWide voltage tolerance\u003c\/strong\u003e—handles input up to 35 V and output up to 70 V, accommodating 12 V, 24 V, and 48 V systems\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLow power consumption\u003c\/strong\u003e—maximum pull-down current approximately 30 mA, with short-circuit protection\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eEngineered for Demanding Mobile and Off-Grid Applications\u003c\/h3\u003e\n\u003cp\u003eThis remote cable is essential for installations where the \u003cstrong\u003eOrion-Tr Isolated DC-DC charger\u003c\/strong\u003e charges a lithium house battery from an alternator or starter battery, and the BMS must actively manage charging. Without proper isolation, voltage differences between battery banks can cause erratic behaviour or damage. The Victron remote cable eliminates this risk, making it a critical component in \u003cstrong\u003ecaravan, motorhome, marine, and 4WD dual-battery systems\u003c\/strong\u003e.\u003c\/p\u003e\n\u003cp\u003eTypical use cases include:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eConnecting a \u003cstrong\u003eVictron smallBMS\u003c\/strong\u003e or third-party BMS to an Orion-Tr Isolated charger\u003c\/li\u003e\n\u003cli\u003eEnabling automated charge control based on cell voltages, temperature, or state of charge\u003c\/li\u003e\n\u003cli\u003eRetrofitting existing systems where the remote signal must be referenced to the secondary battery\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eInstallation Simplicity\u003c\/h3\u003e\n\u003cp\u003eThe cable comes with clearly labelled wires: two grey wires with ferrules for the charger’s remote terminal, and yellow\/black wires for the BMS interface.
