Battery Monitor BMV-712 Smart

High-precision battery monitor with Bluetooth built-in. 500A shunt. VE.Direct port. Midpoint voltage monitoring.

Know Your Battery at All Times

The BMV-712 Smart is a high-precision battery monitor that measures voltage, current, and state of charge. It calculates remaining time, tracks historical data, and gives you complete visibility of your battery bank's health — so you never face unexpected discharge.[citation:1]

Bluetooth Built-in — No Dongle Needed

With Bluetooth integrated directly into the unit, you can monitor your battery via the free VictronConnect app on your smartphone or tablet. Customise settings, view all important data on one screen, access historical records, and update software when new features become available.[citation:2][citation:3]

VE.Direct Port for Full System Integration

Unlike previous models where the Bluetooth dongle occupied the VE.Direct port, the BMV-712 keeps this port free. Connect to a Cerbo GX or other GX device for local monitoring and remote access via the VRM portal — without sacrificing Bluetooth functionality.[citation:3]

Midpoint Voltage Monitoring

One bad cell can destroy an entire battery bank. The BMV-712 monitors the midpoint voltage of series-connected batteries, providing early warning of cell imbalance or failure — helping you protect your investment before it's too late.[citation:2][citation:8]

Auxiliary Input for More Data

The secondary input can monitor a second battery (e.g., starter battery), measure battery temperature with an optional sensor, or track midpoint voltage — giving you a complete picture of your entire electrical system.[citation:1]

Programmable Relay for Automation

Use the built-in programmable relay to turn off non-critical loads, start a generator when battery voltage drops, or trigger an alarm. Automate your system for worry-free operation.[citation:7][citation:10]

VE.Smart Networking for Wireless Data Sharing

When connected via Bluetooth to other Victron products, the BMV-712 provides real-time battery voltage, temperature, and current data to solar chargers and AC chargers — enabling coordinated, intelligent charging without extra wiring.[citation:1][citation:9]

Very Low Current Draw

Consumes only 0.7Ah per month (1mA) at 12V — negligible impact on your battery bank. Perfect for long-term off-grid installations and vehicles in storage.[citation:2][citation:6]
