Victron RJ12 UTP Cable for BMV Battery Monitors (0.3m–30m)

The cable that connects your Victron BMV battery monitor to its shunt. A factory RJ12 ships in the box with every BMV-700, BMV-702, and BMV-712 — this is the replacement when the factory length is too short for a long shunt-to-head run, or too long and you want to tidy up the slack behind the panel.

• BMV-700 / BMV-702 / BMV-712 only. The RJ12 carries the proprietary BMV head-to-shunt signal. It does not work with the SmartShunt (self-contained, no head unit) or any VE.Bus / VE.Can / VE.Direct device.
• Eight lengths, from 0.3m (head unit directly above the shunt) to 30m (nav station to engine room on a larger vessel). Per-length picking guidance shows below when you select a variant.
• Plug-and-play replacement. Drop in for the factory cable that shipped with your BMV — no tools, no adapters.
• Genuine Victron Energy cable — full 5-year Victron warranty.

Most buyers reach this page because the factory cable doesn't fit their install — the shunt is sitting on the negative bus near the battery bank while the BMV head unit is panel-mounted at the nav station or RV main panel. Measure the actual routed distance (with a little slack) before ordering.
