Victron BMV Battery Monitor (700 or 702 or 712)
Victron BMV Battery Monitors
Knowing exactly what’s going on with your batteries is the difference between guessing and having true confidence in your off-grid power system. Victron’s BMV series battery monitors are designed to give you clear, accurate insight into your battery’s state of charge, usage, and health. At Autarky Expedition Vehicles, we recommend the BMV line because it keeps you in control, whether you’re running a compact camper van or a full expedition truck.
BMV-700
The entry-level classic. The BMV-700 covers the essentials: real-time battery voltage, current draw, state of charge, and time-to-go estimation. Perfect for smaller systems or anyone who just wants the core data without extra complexity.
Best for: Van conversions, smaller off-grid systems, or budget-conscious builds that need solid battery monitoring.
BMV-702
Everything the 700 offers, plus the ability to monitor a second battery or midpoint voltage. This makes it ideal if you want to keep an eye on a starter battery alongside your house battery, or track midpoint balance in larger banks.
Best for: RVs, expedition trucks, or marine applications where monitoring both house and starter batteries is important.
BMV-702 Black
Functionally identical to the BMV-702, but with a sleek black finish. It’s a great choice if you want your monitoring system to blend seamlessly into a modern interior or dark control panel layout.
Best for: Style-conscious builds or anyone who prefers a clean, modern look without losing functionality.
BMV-712 Smart
The top of the line. The BMV-712 adds built-in Bluetooth, letting you view your system directly on your phone through the VictronConnect app. No need to wire extra displays—everything is wireless, simple, and customizable.
Best for: Advanced off-grid systems, remote monitoring, or anyone who wants maximum convenience and real-time data on the go.
At a glance:
- BMV-700: Core essentials
- BMV-702: Adds second battery/midpoint monitoring
- BMV-702 Black: Same as 702, modern black finish
- BMV-712 Smart: Bluetooth-enabled, mobile monitoring
Whichever model you choose, Victron’s BMVs give you the insight to protect your batteries, extend their life, and power your adventures without worry.
Victron BMV-712 has Bluetooth inside
With Bluetooth built-in, the BMV Smart is ready for the Internet of Things (IoT) era. With Bluetooth being implemented in most other Victron Energy products, wireless communication between products will simplify system installation and enhance performance.

Victron BMV-712 is Easy to install
All electrical connections are to the quick connect PCB on the current shunt. The shunt connects to the monitor with a standard RJ12 telephone cable. Included: RJ 12 cable (10 m) and battery cable with fuse (2 m); no other components needed.
Also included are a separate front bezel for a square or round display appearance, a securing ring for rear mounting and screws for front mounting.
Midpoint voltage monitoring
One bad cell or one bad battery can destroy a large, expensive battery bank. When batteries are connected in series, a timely warning can be generated by measuring the midpoint voltage. Please see the BMV manual, section 5.2, for more information.
We recommend our Battery Balancer (BBA000100100) to maximize service life of series-connected lead-acid batteries.
Very low current draw from the battery
Current consumption: 0,7Ah per month (1mA) @12V and 0,6Ah per month (0,8mA) @ 24V
Especially Li-ion batteries have virtually no capacity left when discharged until low voltage shutdown. After shutdown due to low cell voltage, the capacity reserve of a Li-ion battery is approximately 1Ah per 100Ah battery capacity. The battery will be damaged if the remaining capacity reserve is drawn from the battery. A residual current of 10mA for example may damage a 200Ah battery if the system is left in discharged state during more than 8 days.
Bi-stable alarm relay
Prevents increased current draw in case of an alarm.
