Product Information

Full details

The Victron Energy ASS030720050 VE.Can to CAN-bus BMS Cable (Type B) is an essential integration tool for off-grid and marine enthusiasts who need to bridge communication between third-party lithium batteries and a Victron Energy system. This 5-meter cable ensures your battery management system (BMS) can reliably report state-of-charge and health data to your Victron monitoring hardware. While it simplifies complex setups, users must carefully verify that their specific battery bank requires a 'Type B' wiring configuration to avoid communication errors or potential system faults.

Extended Product Information

FAQs

How do I know if I need Type A or Type B?

You must check the documentation provided by your battery manufacturer. They will explicitly state which pinout configuration is required for communication with Victron equipment.

Can I use this cable with any brand of lithium battery?

No. The battery must have a CAN-bus communication port that uses a compatible protocol. Always verify compatibility on the Victron Energy website or the battery manufacturer's support page.

Can I extend the 5-meter length if it is too short?

It is generally recommended to use the cable as supplied. Extending it may introduce signal degradation or noise, potentially interrupting the CAN-bus communication.

Does this cable provide power to the battery management system?

No, this is a data communication cable. It is intended for transmitting digital signals only and does not supply power to the battery's internal systems.

What should I do if the battery shows an error code after connection?

Disconnect the cable and check the battery manual to see if a specific handshake or communication sequence is required upon initiation.

Troubleshooting

Battery is not detected by the Victron GX device

Verify the cable is securely plugged into the correct ports and confirm the battery brand is listed as compatible with your firmware version.

Intermittent communication drops

Check the cable for physical damage or sharp kinks and ensure it is not running alongside high-current power cables that could cause electromagnetic interference.

Pros and Cons

Pros

  • Ensures accurate data reporting from third-party BMS
  • Long 5-meter reach allows for flexible component placement
  • Enables advanced charging protocols for non-Victron lithium batteries
  • Rugged construction suitable for marine and mobile environments

Cons

  • Requires specific knowledge of battery communication protocol (Type A vs Type B)
  • Not compatible with all battery brands without prior verification
  • 5-meter length may require cable management in tight spaces

Setup, Compatibility & Care

Before installation, ensure your Victron GX device firmware is updated to the latest version to support third-party BMS integration. When connecting, locate the RJ45 CAN-bus port on your battery and the VE.Can port on your Victron device. Use the provided 5-meter cable to establish the link.

Crucially, consult your battery manufacturer's documentation to confirm if they support the 'Type B' pinout configuration. Using a 'Type B' cable on a system requiring 'Type A' can result in a failure to communicate or even damage to the ports. For care, avoid bending the cable at sharp angles or placing it under tension, as this can damage the internal conductors and lead to intermittent signal drops.
