Victron Energy BMV-712 Smart Battery Monitor with Shunt – 6.5–70 VDC, Bluetooth & In-App Insights

Smart, scalable battery monitoring for diverse systems

Designed for demanding power setups, the Victron Energy BMV-712 Smart Battery Monitor with Shunt provides clear visibility into a battery bank's health and performance across a wide voltage range from 6.5 to 70 VDC. It tracks essential metrics such as the percent state of charge, voltage, current, and the remaining energy or time, helping you anticipate needs and plan charging strategies without guesswork. The built-in display, combined with in-app charts in Victron Connect, offers a straightforward snapshot of live conditions and historical trends, so you can see how your system behaves over time.

Core capabilities that fit your system

• Wide voltage coverage supports everything from compact 12 V setups to larger 48–70 V configurations.
• An additional programmable input can measure battery temperature, midpoint voltage, or the voltage of a second battery, while a programmable relay lets you automate devices like fans or chargers.
• Integrated Bluetooth enables wireless monitoring on phones and tablets; for global access, pair with a GX device and VRM via VE.Direct (sold separately).
• The on-device display shows SOC, voltage, current, and energy remaining; Victron Connect expands view to historical data and charts.
• Setup is flexible and approachable, either directly on the display or through Bluetooth pairing, with caution about high-voltage usage.

Connectivity, data, and real-world relevance

• Bluetooth keeps essential readings at your fingertips during maintenance, travel, or daily use.
• VRM remote viewing provides peace of mind when away from the installation site, with secure access via GX devices.
• Historical data and charts help you identify patterns, peaks, and opportunities to optimize charging windows.

Real-life use cases you might consider

In a recreational vehicle or sailboat, the BMV-712 helps you gauge when to charge or conserve energy, aligning with solar production or generator use. For off-grid cabins or tiny homes, it supports energy budgeting by offering a clear read on remaining energy. In multi-battery installations, the second-battery input and chosen sensors give you deeper visibility into balance and health, while the relay offers a simple way to trigger ventilation, cooling fans, or charging racks when thresholds are reached.

Safety, installation, and professional guidance

Because high-voltage systems are involved, proper installation matters. Avoid hazards by following applicable electrical codes and, when needed, consulting a licensed technician. The shunt is housed in a dedicated enclosure designed for protection in demanding environments.
