Victron 5m VE.Can to CAN-Bus BMS Type B Cable

DESCRIPTION

Victron VE.Can to CAN-Bus BMS Type B Cable: Reliable 5m Communication Link for GX Devices

Purpose-Built CAN-Bus Cable for Victron Energy Systems

The Victron VE.Can to CAN-Bus BMS Type B Cable (5m) provides a dedicated, plug-and-play communication pathway between your CAN-bus enabled battery and a Victron GX device. Engineered to exacting specifications, this cable ensures stable data exchange, allowing your GX system to monitor battery status, state of charge, and critical parameters in real time. Without a properly connected BMS cable, the battery may not appear on the GX display and could shut down unexpectedly, risking power loss to connected equipment.

This 5-metre cable is ideal for installations where the battery bank and GX device are positioned at a distance, such as in larger off-grid power systems, marine setups, or vehicle-based energy solutions. The flexible blue jacket and moulded RJ45 connectors with clear labels simplify routing and identification, reducing installation time and the potential for wiring errors.

Type B Pinout for Specific Battery Compatibility

This Type B cable (part number ASS030720050) is designed for batteries that require a specific CAN-bus pin configuration. It is compatible with a wide range of lithium battery models, including:

  • Pylontech US2000, US3000, UP2500
  • LG Chem Resu
  • AXIstorage 7S/9S
  • BMZ
  • BSLBATT Lithium Battery
  • Solar MD BMS EX
  • Freedom Won eTower

Using the correct cable type is essential. The Type B cable differs from the Type A variant in its internal wiring, matching the CAN-H, CAN-L, and GND pin assignments required by the listed batteries. Connecting an incompatible cable can prevent communication, leading to system faults or battery shutdown. Always verify your battery model against the compatibility list before installation.

Key Features

  • 5-metre length provides flexibility for installations where the GX device and battery are not adjacent
  • Clear labelling on each connector: "Victron VE.Can" and "CAN-bus BMS" to prevent misconnection
  • Moulded RJ45 plugs ensure secure, strain-relieved connections that resist vibration and corrosion
  • Flexible blue jacket allows easy routing through conduits, cable trays, and tight spaces
  • Precise Type B pinout guarantees compatibility with specified battery models, eliminating guesswork
  • Plug-and-play installation – no crimping, soldering, or custom wiring required

Why a Dedicated BMS Cable Matters

In a Victron Energy ecosystem, the GX device (such as a Cerbo GX or Color Control GX) acts as the central communication hub. It relies on accurate battery data to optimise charging, manage loads, and protect the battery from over-discharge or over-voltage conditions. A generic network cable may not have the correct pinout or shielding, leading to intermittent data, incorrect readings, or complete communication failure. The Victron VE.Can to CAN-Bus BMS Type B Cable is purpose-built to maintain signal integrity, reducing the risk of system downtime and protecting your investment in premium energy storage.

Installation Guidance

Connect the end labelled "CAN-bus BMS" to the CAN port on your master battery. Plug the "Victron VE.Can" end into a VE.Can or BMS-Can port on your GX device. If using a VE.Can port, configure it to CAN-bus BMS (500 kbit/s) in the GX settings. Install the supplied VE.Can terminator in the second VE.Can socket on the GX device. Once connected, the battery should appear on the GX display, confirming successful communication.

For systems with multiple battery modules, use the manufacturer-supplied RJ45 cables to link the batteries together via their link ports. The master battery is the one with an empty link port 0. No DIP switch adjustments are typically required; the batteries will auto-detect and synchronise.

Built for Demanding Environments

Whether installed in a marine engine room, a remote off-grid shed, or a vehicle subjected to constant movement, this cable is designed to withstand harsh conditions. The robust RJ45 connectors resist corrosion, while the durable jacket protects against abrasion and UV exposure. This ensures long-term reliability and consistent performance, even in high-vibration or high-humidity settings.

Complete Your Victron System with Confidence

Ensure seamless communication between your battery and GX device with the Victron VE.Can to CAN-Bus BMS Type B Cable (5m). Order today to maintain full visibility and control over your energy storage system, and avoid the downtime that comes with unreliable connections.

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.

During the warranty period, Victron Energy will, at its discretion, repair, replace or (partly) credit 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:

  • Reversed battery polarity.
  • Inadequate connection.
  • Mechanical shock or deformation.
  • Contact with liquid or oxidation by condensation.
  • Use in an inappropriate environment (dust, corrosive vapour, humidity, high temperature, biological infestation, etc.).
  • Breakage or damage due to lightning.
  • Connection terminals and screws destroyed or other damages, like overheating, due to insufficient tightening.
  • For any electronic breakage except due to lightning (reverse polarity, over‐voltage due to external cause), the state of the internal control diode and/or the input/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 other than Victron Energy or one of its authorized Repair Centres. In order to qualify for the warranty, the product must not be disassembled or modified.

This warranty and our warranty obligations thereunder (repair, replacement or credit) are the direct customer’s and, if applicable, the end-user’s sole rights and remedies and our sole obligations with respect to any defective and/or non-conforming product or breach of warranty and is subject to and without prejudice to the limitations of liability in this warranty.

Victron Energy shall not be liable for damages, whether direct, incidental, special, or consequential, even caused by negligence or fault.

As a product requires service, it must be brought back to the place of purchase. In case no contact can be made with the merchant, or if he is either unable or not allowed to provide service, direct contact should be made with Victron Energy through the support section on Victron’s website.

In case Victron Energy replaces a product, it will own the replaced product. Victron Energy owns all parts removed from repaired products. Victron Energy uses new or reconditioned parts made by various manufacturers when performing warranty repairs or building replacement products.

If Victron Energy repairs or replaces a part of a product, its warranty term is not extended: the warranty will apply for the remaining term of the original warranty term. For example, if Victron Energy replaces a product with a 5-year warranty after 3 years, the warranty of this product will apply for another 2 years, with a minimum of 6 months.

All remedies and the measure for damages are limited to the above. Victron Energy shall in no event be liable for consequential, incidental, contingent or special damages, even if having been advised of the probability of such damages.

The foregoing limited warranty provided by Victron Energy is in lieu of any other warranties, express or implied arising by law, course of dealing, course of performance, usage of trade or otherwise, of any kind whatsoever including, without limitation, warranties of merchantability or fitness for a particular purpose, with respect to any product. The above is without prejudice to the arrangement for consumers detailed above.
