DESCRIPTION

Victron VE.Can to CAN-Bus BMS Type B Cable 1.8m: Reliable Communication for Your Energy Storage System

Purpose-Built Cable for Seamless BMS Integration

The Victron VE.Can to CAN-Bus BMS Type B Cable (part number ASS030720018) is a dedicated 1.8-metre communication link designed to connect compatible lithium battery modules to Victron GX devices. Engineered for precision, this cable ensures stable data exchange between your battery management system (BMS) and the monitoring platform, enabling accurate state-of-charge readings, charge/discharge control, and system protection. Without a properly configured connection, the battery may not appear on the GX device display and could shut down unexpectedly, risking power loss to critical loads.

Why a Dedicated Cable Matters

Generic network cables often lack the correct pin-out and impedance matching required for CAN-bus communication at 500 kbit/s. Using an incorrect cable can lead to intermittent data errors, battery communication dropouts, or even system instability. The Victron Type B cable eliminates these risks with a factory-defined wiring scheme: GND on pin 3 (Victron side) to pin 2 (battery side), CAN-L on pin 8 to pin 5, and CAN-H on pin 7 to pin 4. This precise configuration is essential for batteries such as Pylontech US2000, US3000, UP2500, LG Chem Resu, AXIstorage, BMZ, BSLBATT, Solar MD, and Freedom Won eTower.

Key Features

  • Correct Pin-Out for Type B Batteries: Pre-wired to match the CAN-bus BMS interface of specific lithium models, avoiding the need for custom crimping or guesswork.
  • 1.8-Metre Length: Provides flexibility in equipment placement without excessive slack that could introduce signal noise.
  • Clear Labelling: "CAN-bus BMS" on the battery end and "VE.Can" on the GX end prevent installation errors.
  • Durable Construction: Blue PVC jacket and RJ45 connectors built to withstand typical installation environments.
  • Plug-and-Play: No software configuration needed on the cable itself; simply connect and set the GX device port profile to CAN-bus BMS (500 kbit/s) if using a VE.Can port.

Installation Guidance

Connect the end labelled "Battery BMS" to the CAN port of the master battery. On the GX device, use a dedicated BMS-Can port if available; otherwise, assign a VE.Can port to the CAN-bus BMS profile. Insert the supplied VE.Can terminator into the remaining VE.Can socket on the GX device. Note that the standard Pylontech communication cable cannot substitute for this connection between the master battery and the GX device. For systems with multiple battery modules, inter-battery linking still uses the manufacturer-supplied RJ-45 cables via the link ports.

Compatibility and System Confidence

This cable is specifically listed for use with AXIstorage 7S/9S, BMZ, BSLBATT Lithium Battery, LG Chem Resu, Pylontech US2000/US3000/UP2500, Solar MD BMS EX, and Freedom Won eTower. Always verify compatibility with your battery’s documentation. A reliable BMS communication link is critical for preventing unexpected shutdowns and ensuring that firmware updates or settings changes on connected devices proceed safely while the battery remains online.

Secure Your System’s Communication

Add the Victron VE.Can to CAN-Bus BMS Type B Cable to your installation kit today and maintain uninterrupted visibility and control over your energy storage. A stable BMS connection is the foundation of a dependable off-grid or backup power system.

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. 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 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.

Life Support Policy

As a general policy, Victron Energy does not recommend the use of any of its products in life support applications where failure or malfunction of Victron Energy's product can be reasonably expected to cause the failure of the life support device or to significantly affect its safety or effectiveness. Victron Energy does not recommend the use of any of its products in direct patient care. Victron Energy will not knowingly sell its products for use in such applications unless it receives in writing assurances satisfactory to Victron Energy that the risks of injury or damage have been minimized, the customer assumes all such risks, and the liability of Victron Energy is adequately protected under the circumstances.
