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
Direct Customers
Victron Energy provides the following warranty to any direct customer (OEM, distributor or dealer) in relation to any products that Victron Energy has directly sold to the direct customer. This warranty is not an end-user warranty between Victron Energy and an end-user, and end-users shall not have any rights or remedies under this limited warranty towards Victron Energy directly. The direct customer shall, in turn, ensure that the end-user is provided with a warranty identical to this warranty, subject to applicable local mandatory law.
End-Users
Victron Energy may also provide a warranty directly to end-users, in which case the below warranty conditions equally apply to such warranty. In that case, end-users shall claim their warranty at their place of purchase or through the original direct customer of Victron, which can be found through the support section on Victron’s website https://www.victronenergy.com/support. Hence, the direct customer shall on behalf of Victron Energy deal with any warranty claims made under any warranty that Victron Energy may provide directly to end-users. This support section on Victron’s website https://www.victronenergy.com/support will provide further guidance on the procedure for end-users to make a claim under this limited warranty.
If the end-user is a consumer – a natural person who is acting for purposes which are outside that person's trade, business, craft or profession – the following applies. The rights and remedies granted to the consumer under this limited warranty are without prejudice to the consumer’s statutory rights. Furthermore, the consumer is entitled by law to remedies from the seller free of charge in the event of a lack of conformity of the goods (such as repair, replacement, price reduction or rescission), which remedies are not affected by this limited warranty.
Warranty
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 original 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 original end-user, with a maximum of 30 months from the Victron Energy invoice date, Lithium batteries: 3 years from date of purchase by the original end-user, with a maximum of 42 months from the Victron Energy invoice date. In addition to this, proof of correct battery usage is required when making a battery warranty claim.
For a 10% surcharge on the current net price for products that came with a 5-year warranty, an additional 5 years of warranty can be purchased by Victron’s direct customers, bringing the total warranty to 10 years. Warranty extensions need to be applied for ultimately one year before the expiration of the original term. Victron may ask proof that the product was still functional at the time of purchase of the extended warranty.
