Victron Energy BMV-712 Smart Battery Monitor 6.5–70 VDC — Bluetooth & Integrated Shunt for Accurate State-of-Charge

The BMV-712 Smart combines a high-accuracy current shunt, a clear display and wireless communication so you can reliably track battery condition and consumption in boats, RVs, off-grid homes and industrial setups. It supports an extra input for temperature, midpoint or a second battery, plus a programmable relay for alarms or controls. The device pairs locally via Bluetooth to Victron Connect and can integrate with Victron GX systems for remote monitoring.

How does the BMV-712 Smart tell me the real state of charge?

This monitor uses precise current measurement through the included shunt plus voltage sensing and programmable battery capacity to calculate state-of-charge and energy remaining. It compensates for charge/discharge history so the displayed percentage reflects usable capacity rather than just voltage.

• Integrated shunt for accurate ampere-hour tracking
• Displays % state-of-charge and ampere readings
• Energy/time remaining estimates based on usage patterns
• Historical data logged and viewable in Victron Connect

What connectivity and remote monitoring options are available?

The unit includes built-in Bluetooth for smartphone and tablet monitoring via the Victron Connect app. For system-wide remote access, connect to a Victron GX device with a VE.Direct cable (sold separately) to upload data to VRM for worldwide monitoring.

• Bluetooth for quick local setup and status checks
• Compatible with Victron Connect for charts and configuration
• VE.Direct integration enables VRM cloud monitoring when paired with GX hardware
• Data logging lets you review historical performance trends

What extra inputs and outputs can I use with this monitor?

The BMV-712 Smart offers an additional configurable input to measure battery temperature, a midpoint voltage, or the voltage of a second battery bank. It also includes a programmable relay that can trigger alarms, control a contactor, or take other actions based on set thresholds.

• Additional input: temperature, midpoint, or second battery voltage
• Programmable relay for alarms or automated control tasks
• Customizable thresholds and behavior via display or app
• Flexible use cases: battery protection, charging control, remote alerts

How do I install the BMV-712 Smart safely and correctly?

Installation involves wiring the shunt into the negative battery line so all current flows through it; since the shunt handles high currents and voltages, follow local electrical codes and the product manual. If you’re not confident with DC high-voltage wiring, hire a licensed electrician or qualified marine/RV technician to avoid hazards.

• Mount shunt in its enclosure and route main negative conductor through it
• Place display within view and run the communication cable to the shunt
• Program battery capacity and parameters via display or Bluetooth app
• Consult a professional for high-voltage or complex multi-bank systems

Who is this for? The Victron Energy BMV-712 Smart is aimed at DIYers and professionals installing battery systems in boats, recreational vehicles, off-grid homes and light industrial applications who need accurate ampere-hour accounting, wireless access to battery data, and flexible integration with other Victron components. Choose this model when you want precise state-of-charge tracking, historical logging, and the option to expand monitoring with GX devices and VRM cloud access. Always adhere to safety guidelines and seek professional installation for high-voltage or multi-bank systems.
