Victron Energy VE.Can to CAN-bus BMS Type B Cable, 1.8m

Overview

The Victron Energy ASS030720118 is a VE.Can to CAN-bus BMS Type B cable for linking a compatible CAN-bus enabled battery to a Victron system. It is a 1.8 m cable, about 5.9 ft, used where the battery installation calls for the Victron Type B CAN-bus BMS wiring layout.

This cable is commonly used in marine Victron installations where a GX device needs battery data from a supported third-party lithium battery. On a boat, that communication link matters for monitoring state of charge, alarms, and system behavior from the helm, nav station, or electrical locker.

One end is labeled for the CAN-bus BMS side at the battery, and the VE.Can end connects to a compatible Victron GX device through its VE.Can or BMS-Can port. Battery brand and model compatibility should be checked against the battery installation guidance before fitting, since Victron Type A and Type B CAN-bus BMS cables use different pin layouts.

Key features

• 1.8 m cable length gives practical reach for nearby battery-to-GX installations in compact marine electrical spaces.
• Type B CAN-bus BMS wiring for battery systems that require the Victron Type B cable layout.
• Connects a CAN-bus enabled non-Victron battery to a Victron GX-based monitoring and control system.
• VE.Can side connects to a compatible GX device through the VE.Can or BMS-Can port.
• Battery side is labeled for the CAN-bus BMS connection, helping reduce mix-ups during installation.
• Useful for lithium battery installations where battery communication is needed for system monitoring rather than only basic voltage sensing.

Installation and setup

Install the cable with the CAN-bus BMS end at the battery and the VE.Can end at the Victron GX device. The Type B pin-out is specific, so it should not be treated as a generic straight-through network patch lead unless the battery documentation explicitly allows that wiring.

After connection, configure the GX device for the battery system being used. In many installations, a VE.Can terminator may also be required in the remaining VE.Can socket on the GX device, depending on the full network layout.

Compatibility and fit

This cable is for CAN-bus enabled batteries that call for the Victron VE.Can to CAN-bus BMS Type B cable. Examples commonly associated with the Type B cable include AXIstorage 7S and 9S, BMZ, BSLBATT Lithium battery, LG Chem RESU, Pylontech US2000, US3000, and UP2500, Solar MD BMS EX, and Freedom Won eTower.

It is a good match for marine systems built around Victron monitoring hardware, especially cruisers, fishing boats, and off-grid vessels using lithium battery banks where the battery BMS needs to communicate with the onboard power system.

Shipping
We ship worldwide from the United States. Rates are calculated at checkout based on destination and package weight. Some items include free shipping, which will show automatically. Not every product is eligible for international shipping; checkout will confirm eligibility. We do not ship to PO Boxes except through USPS, and not all packages qualify.

Delivery and tracking
Deliveries are handled by trusted carriers such as USPS, UPS, FedEx, and DHL. Estimated arrival times appear at checkout and depend on your location and the service you choose. These are estimates and can be affected by customs or carrier disruptions. A shipping confirmation with a tracking link is emailed when your order ships, and tracking may take up to 24 hours to update. You can also view tracking in your account.

Duties, taxes, and support
International customers are responsible for any customs duties, taxes, and fees charged by the destination country. If these charges are refused and a shipment returns to us, the carrier’s return cost and any re-entry customs fees will be deducted from the refund. If your order is late or you need help, contact cs@qualityboatparts.com and we will assist you.

Quality Boat Parts is a reseller. Many items include a manufacturer’s warranty, and all warranty service is handled directly by the manufacturer. We do not manage or administer warranty claims on behalf of customers.

Warranty terms, coverage, and duration are set by each manufacturer. Issues involving defects, repairs, or replacements must be addressed with the manufacturer’s support team. When available, the warranty period is listed on the product page. If it is not shown, contact us or the manufacturer for details before purchasing.

To start a claim, the customer must contact the manufacturer and follow their process. Keep your proof of purchase and original packaging, and register the product if the manufacturer requires it, as these are often needed for warranty service.

We are happy to help you find the right contact or documentation, but we cannot decide outcomes or intervene in claim resolutions. For guidance, email cs@qualityboatparts.com.
