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. See the full cables collection for RJ45, VE.Direct, and other Victron comm cables, or book a system consultation if you're building a fresh monitoring system and want our ABYC-certified Advisors to spec the parts list.
