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.
