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.
