Description
High-Precision Battery Monitor with 500A Shunt, VE.Direct, and State of Charge Display 6.5V to 95V, IP55, 0.01A Resolution.
Product Overview
The Victron BMV-700 (BAM020700000R) is a high-precision battery monitor that calculates and displays state of charge, time to go, voltage, current, power, and ampere-hours consumed giving a complete real-time and historical picture of battery health and usage in 12V, 24V, 48V, and higher-voltage battery systems up to 95V DC.
At the core of the BMV-700 is a 500A quick-connect shunt with a 0.01A (10mA) current measurement resolution capturing even small trickle currents that basic monitors miss. Complex software algorithms account for discharge rate, temperature effects, and battery age to deliver an accurate state of charge reading rather than a simple voltage-based estimate. Programmable alarms, a programmable relay output, and VE.Direct connectivity for Victron GX device integration complete the feature set. Installed via flush mount with a 63mm round or 69mm × 69mm square bezel, everything needed for installation is included in the box RJ12 cable (10m) and a 2m battery cable with fuse.

Features & Benefits
-
State of Charge with Intelligent Algorithm — The BMV-700 calculates state of charge using software algorithms that account for discharge current, temperature effects, and battery age — delivering far greater accuracy than a simple voltage-based reading, which cannot distinguish between a fully charged battery at rest and one that is merely recovering after a load is removed.
-
Time to Go Display — Based on the current rate of discharge and remaining capacity, the BMV-700 calculates how long the battery will last at the present consumption rate — one of the most practically useful readings for caravan, marine, and off-grid users managing daily energy budgets.
-
500A Quick-Connect Shunt — The included 500A shunt covers the majority of 12V and 24V auxiliary battery installations. For larger systems, the BMV-700 supports shunt selection up to 10,000A via the settings menu — the same monitor hardware covers everything from small camper trailers to large commercial battery banks.
-
0.01A (10mA) Current Resolution — The BMV-700 resolves current to 10 milliamps — capturing small loads such as LED lighting, monitoring electronics, and parasitic draws that coarser monitors miss. This fine resolution improves the accuracy of Ah consumed calculations, particularly in systems with many small intermittent loads.
-
Wide Voltage Range: 6.5V – 95V — Covers 6V, 12V, 24V, and 48V battery systems, as well as higher-voltage applications up to 95V — a single monitor for the full range of common battery system voltages.
-
Programmable Relay Output — A built-in programmable relay can be configured to shed non-critical loads when the battery reaches a low state of charge, start a generator, or trigger any other switched action. Pairs with the BMV-700's alarm functionality for a fully automated load management response.
-
Programmable Visual and Audible Alarm — Custom alarm thresholds for state of charge, voltage, current, and temperature can be set to alert the user before a critical battery condition is reached — providing advance warning rather than a post-failure notification.
-
Historical Data Logging — The BMV-700 stores a comprehensive history of battery events and usage patterns, which can be reviewed to assess battery health over time, identify unusual discharge events, and evaluate charging system performance.
-
VE.Direct for GX Integration — The VE.Direct port connects to Victron GX devices (Cerbo GX, CCGX, Venus GX) for system-level monitoring, data logging, and integration with broader Victron energy management.
-
Bluetooth Smart Option — The BMV-700 supports Bluetooth monitoring via the optional Victron Bluetooth Smart dongle (sold separately) — enabling smartphone and tablet monitoring via the VictronConnect app without a GX device.
-
Complete Installation Kit Included — RJ12 shunt-to-monitor cable (10m), 2m battery cable with fuse, round and square front bezels, rear securing ring, and screws are all included. No additional components are required for a standard installation.
-
IP55 — Protected Against Dust and Water Jets — IP55 provides full dust protection and resistance to low-pressure water jets from any direction — suitable for sheltered indoor installations in engine bays, caravans, and enclosed battery compartments. Not rated for outdoor or fully exposed installation.

Frequently Asked Questions
What is the difference between the BMV-700 and the BMV-702?
The BMV-700 monitors a single battery. The BMV-702 adds a second input that can be configured to monitor a second battery voltage, battery temperature, or midpoint voltage — making it the preferred choice for systems with a second battery bank or those requiring midpoint voltage monitoring for large series-connected battery banks.
What does "state of charge" mean and why is it more useful than voltage?
State of charge (%) is a calculated estimate of how much energy remains in the battery relative to its full capacity. Battery voltage is a poor indicator of remaining capacity — it varies with load, temperature, and recovery time. The BMV-700's algorithm accounts for actual current flow in and out of the battery for a far more accurate and stable reading than voltage alone.
Does the BMV-700 include Bluetooth?
No. Bluetooth monitoring requires the optional Victron Bluetooth Smart dongle, sold separately. Without it, the BMV-700 displays via its panel-mounted screen and connects to GX devices via VE.Direct.
Can the BMV-700 monitor a 48V lithium battery system?
Yes. The 6.5V to 95V supply voltage range covers 48V systems. Configure the battery type, capacity, and charge parameters in the BMV-700 settings to match your specific lithium battery specifications.
What does the programmable relay output do?
The relay output can be configured to activate based on any programmable threshold — such as disconnecting non-critical loads when state of charge drops below a set level, starting a generator, or triggering an external alarm. It provides automated load management without requiring manual intervention.
