DESCRIPTION
Victron Orion-Tr Isolated DC-DC Charger Remote Cable: Reliable BMS Integration for Dual-Battery Systems
Purpose-Built Remote Control for Isolated Orion-Tr Chargers
The Victron Orion-Tr Isolated DC-DC Charger Remote Cable enables seamless integration between your Orion-Tr Isolated DC-DC charger and a secondary battery’s Battery Management System (BMS). 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 lithium battery systems where the BMS controls charging. By providing electrical isolation, it ensures safe, accurate signalling without ground loop interference or voltage mismatch.
How It Works
Inside the cable’s encapsulated inline junction, an opto-isolator circuit 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 lithium battery bank from overcharging or operating outside safe parameters, extending battery life and system reliability.
Key Features
- Electrical isolation between primary and secondary battery references prevents ground loops and voltage conflicts
- Pre-crimped wire ferrules for quick, secure connection to the Orion-Tr remote terminal and BMS control ports
- Encapsulated inline junction resists moisture and vibration, suitable for engine bays and harsh mobile environments
- Wide voltage tolerance—handles input up to 35 V and output up to 70 V, accommodating 12 V, 24 V, and 48 V systems
- Low power consumption—maximum pull-down current approximately 30 mA, with short-circuit protection
Engineered for Demanding Mobile and Off-Grid Applications
This remote cable is essential for installations where the Orion-Tr Isolated DC-DC charger 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 caravan, motorhome, marine, and 4WD dual-battery systems.
Typical use cases include:
- Connecting a Victron smallBMS or third-party BMS to an Orion-Tr Isolated charger
- Enabling automated charge control based on cell voltages, temperature, or state of charge
- Retrofitting existing systems where the remote signal must be referenced to the secondary battery
Installation Simplicity
The 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. The compact inline junction can be secured with cable ties, and the pre-crimped ends save time and ensure reliable connections. No additional components or complex wiring are required.

WARRANTY
Victron Energy Limited Warranty Policy
Victron Energy warrants its products to be free from defects in workmanship and materials for a period of 5 years from the date of purchase by the end user, with a maximum of 66 months from the Victron Energy invoice date. Exceptions on this are: lead acid batteries; 2 years from date of purchase by the end user, with a maximum of 30 months from the Victron Energy invoice date, Lithium-ion batteries; 3 years from date of purchase by the end user. In addition to this proof of correct battery usage is required when making a battery warranty claim.
During this period, Victron Energy will, at its option, repair or replace the defective product free of charge. The warranty does not include performing or reimbursing de‐installation, transportation and re‐installation. This warranty will be considered void if the unit has suffered any physical damage or alteration, either internally or externally, and does not cover damages arising from improper use like: • Reverse of battery polarity. • Inadequate connection. • Mechanical shock or deformation. • Contact with liquid or oxidation by condensation. • Use in inappropriate environment (dust, corrosive vapor, humidity, high temperature, biological infestation...). • Breakage or damage due to lightning. • Connection terminals and screws destroyed or other damages, like overheat, due to insufficient tightening. • For any electronical breakage except due to lightning (reverse polarity, over‐voltage due to external cause), the state ofthe internal control diode and of the inputs/output X and Y capacitors determine the warranty.
This warranty will not apply where the product has been misused, neglected, improperly installed, or repaired by anyone else than Victron Energy or one of its authorized Qualified Service Partners. In order to qualify for the warranty, the product must not be disassembled or modified.
Repair or replacement are our sole remedies and Victron Energy shall not be liable for damages, whether direct, incidental,special, or consequential, even caused by negligence or fault.
Victron Energy owns all parts removed from repaired products. Victron Energy uses new or reconditioned parts made by various manufacturers in performing warranty repairs and building replacement products. If Victron Energy repairs or replaces a part of a product, its warranty term is not extended. In case of replacement the new component has a warranty of 6 months, without effect on the initial warranty period. All remedies and the measure for damages are limited to the above. Victron Energy shall in no event be liable for consequential, incidental, contingent orspecial damages, even if having been advised of the probability of such damages.
