Victron ASS030720150 VE.Can CAN-Bus Type B BMS Cable 5 Metre

Connect Third-Party CAN-Bus Batteries to Your Victron System VE.Can to CAN-Bus Type B, 5 Metre.

Product Overview

The Victron ASS030720150 is a 5-metre VE.Can to CAN-Bus BMS cable Type B designed to connect a third-party CAN-bus enabled lithium battery to a Victron power system. Type B is compatible with LG Chem, AXIstorage, BMZ, and Pylontech batteries, enabling direct communication between the battery's BMS and the Victron GX device or VE.Can network for integrated state of charge reporting, cell protection, and charge control.

This is the correct cable for systems pairing a Victron GX device (Cerbo GX, CCGX, Venus GX) with one of the above-listed battery brands. A Type A cable is available separately for BYD battery compatibility. If you are unsure which cable type applies to your battery brand, consult the Victron manual referenced in the product description before purchasing the compatibility list is brand-specific and using the incorrect type will result in a non-functional connection.

Features & Benefits

• Direct BMS-to-GX Communication — Connects the CAN-bus interface of a supported third-party lithium battery directly to the Victron VE.Can network, enabling the GX device to read battery BMS data — including state of charge, cell voltages, temperature, and charge/discharge limits — and use this data to coordinate charging from Victron solar controllers, inverter/chargers, and DC-DC converters.
• 5 Metre Length — The 5m cable length allows flexible mounting of the battery and GX device in installations where proximity is not guaranteed — suitable for larger systems where the battery bank may be located in a separate compartment from the GX control hub.
• Type B — Confirmed Compatible Battery Brands — Specifically designed for LG Chem, AXIstorage, BMZ, and Pylontech batteries. These are among the most widely used third-party lithium battery brands in Australian caravan, off-grid, and marine Victron installations.
• Genuine Victron Accessory — Manufactured to Victron's interface specifications, ensuring correct pin assignment and signal levels for reliable BMS communication without requiring custom wiring or third-party adaptors.

Frequently Asked Questions

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

Type B (this cable) is compatible with LG Chem, AXIstorage, BMZ, and Pylontech batteries. Type A is required for BYD batteries. If your battery brand is not on either list, consult the Victron VE.Can BMS cable manual for current compatibility information before purchasing.

Is a 5m cable the right length for my installation?

The 5m cable suits installations where the battery and GX device are not in close proximity — for example, a battery bank in a separate compartment from the GX control hub. A 1.8m version is available if a shorter run is sufficient. Measure your installation before ordering to avoid an unnecessarily long or short cable run.

What does this cable actually enable in a Victron system?

This cable enables the Victron GX device to receive BMS data from the connected third-party battery — including state of charge, cell-level information, temperature, and charge/discharge current limits. The GX device uses this data to coordinate the behaviour of connected Victron chargers, solar controllers, and inverter/chargers to protect the battery and optimise charging.

Does this cable work with all Pylontech or LG Chem models?

Compatibility is confirmed at the brand level for Pylontech, LG Chem, AXIstorage, and BMZ. Specific model and firmware compatibility within each brand should be verified against the current Victron VE.Can BMS cable compatibility documentation before purchase — Victron updates this list as new battery models are tested and supported.

Can I use this cable without a Victron GX device?

The VE.Can to CAN-Bus BMS cable is designed for use with Victron GX devices that have a VE.Can port. It is not a standalone solution — a compatible Victron GX device is required as the host system for the CAN-bus BMS communication to function.
