xVictron Energy Battery Monitor BMV-700 | BAM010700000
The Victron BMV-700 is a precision battery monitor designed for 12V, 24V and 48V battery systems. It gives installers and off-grid users accurate, real-time data on state of charge, voltage, current and consumed amp-hours. Where a simple voltage reading is not enough, the BMV-700 provides the full picture of what a battery bank is actually doing.
Key Features
- Displays state of charge (%), voltage, current (amps), power (watts), consumed amp-hours and time remaining on a single backlit LCD screen.
- Compatible with 12V, 24V and 48V battery systems, including lead-acid (flooded, AGM, gel) and lithium chemistries.
- High-accuracy coulomb counting via a 500A/50mV shunt, supplied in the box, for precise amp-hour tracking.
- Programmable relay output that can trigger alarms or control external devices based on user-defined thresholds (e.g. low state of charge).
- Stores historical data including deepest discharge, average discharge, number of charge cycles and total amp-hours drawn.
- Compact display head with a 52mm panel cut-out, suitable for mounting in switchboards, caravans, boats and off-grid enclosures.
- Connects to the VictronConnect app via an optional VE.Direct Bluetooth Smart dongle for wireless monitoring on iOS and Android.
Product Overview
The BMV-700 works by measuring the current flowing in and out of a battery bank through a precision shunt resistor. By integrating this current over time, it calculates consumed amp-hours and derives a state of charge figure that is far more reliable than voltage-based estimation alone. This matters in practice because battery voltage is heavily influenced by load, temperature and recent charge history, making it a poor standalone indicator of how much energy is actually available.
The included 500A/50mV shunt is installed in the negative cable of the battery bank. The display unit connects to the shunt via a supplied RJ12 cable and draws its power directly from the battery, so no separate supply is needed. The relay output adds practical flexibility: it can be configured to switch at a set state of charge, voltage level or temperature (with an optional temperature sensor), making it useful for load shedding, generator start signals or audible alarms.
Historical data logging is stored on-board and covers up to 30 days of discharge records alongside lifetime counters. This is useful for commissioning checks, fault diagnosis and advising end users on battery health. The BMV-700 does not include Bluetooth as standard, but the VE.Direct port allows connection to a GX device (such as a Cerbo GX) for integration into a full Victron system with remote monitoring via VRM.

Installation Notes
The shunt must be installed in the main negative cable of the battery bank, between the battery negative terminal and all other negative connections. All negative loads and charge sources must connect to the load side of the shunt, not directly to the battery, or readings will be inaccurate. The display unit is powered directly from the battery via the shunt connection. Installation in battery systems above 48V or in complex multi-bank configurations should be carried out by a qualified electrician or accredited installer. For lithium battery systems, verify compatibility with the battery BMS before installation. The VE.Direct port allows integration with Victron GX devices; no additional configuration software is required for standalone use.
