Victron Energy BMV-702 Black Battery Monitor

The BMV-700 is a high precision battery monitor. The essential function of a battery monitor is to calculate ampere hours consumed and the state of charge of a battery. Ampere hours consumed are calculated by integrating the current flowing in or out of the battery.

Battery ‘fuel gauge’, time-to-go indicator, and much more

The remaining battery capacity depends on the ampere-hours consumed, discharge current, temperature and the age of the battery. Complex software algorithms are needed to take all these variables into account. Next to the basic display options, such as voltage, current and ampere-hours consumed, the BMV series also displays state of charge, time to go, and power consumption in Watts. The BMV features an additional input which can be programmed to measure the voltage (of a second battery), battery temperature or midpoint voltage (see below).

Bluetooth Smart

Use the Bluetooth Smart dongle to monitor your batteries on Apple or Android smartphones, tablets, macbooks and other devices.

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 the rear mounting and screws for the front mounting.

Easy to program (with your smartphone!)

A quick install menu and a detailed setup menu with scrolling texts assist the user when going through the various settings. Alternatively, choose the fast and easy solution: download the smartphone app (Bluetooth Smart dongle needed).

Midpoint voltage monitoring (BMV-702 only)

This feature, which is often used in industry to monitor large and expensive battery banks, is now for the first time made available at a low cost, to monitor any battery bank. A battery bank consists of a string of series connected cells. The midpoint voltage is the voltage halfway along the string. Ideally, the midpoint voltage would be exactly half of the total voltage. In practice, however, deviations will be seen, that depend on many factors such as a different state of charge for new batteries or cells, different temperatures, internal leakage currents, capacities and much more. Large or increasing deviation of the midpoint voltage, points to improper battery care or a failed battery or cell. Corrective action following a midpoint voltage alarm can prevent severe damage to an expensive battery. Please consult the BMV manual for more information.

Additional input to measure voltage (of a second battery), temperature or midpoint voltage, and corresponding alarm and relay settings.

1000A/50mV, 2000A/50mV and 6000A/50mV shunt

The quick connect PCB on the standard 500A/50mV shunt can also be mounted on these shunts.

Interface cables

VE.Direct cables to connect a BMV 70x to the Color Control (ASS030530xxx) VE.Direct to USB interface (ASS030530000) to connect several BMV 70x to a Color Control GX or to a computer.

VE.Direct to Bluetooth Smart dongle

With the VE.Direct to Bluetooth Smart dongle real time data and alarms can be displayed on Apple and Android smartphones, tablets, macbooks and other devices. Also use your smartphone to adjust settings! (the VE.Direct to Bluetooth Smart dongle must be ordered separately).

Colour Control

The powerful Linux computer, hidden behind the colour display and buttons, collects data from all Victron equipment and shows it on the display. Besides communicating with Victron equipment, the Color Control communicates through CAN bus (NMEA2000), Ethernet and USB. Data can be stored and analysed on the VRM Portal.

Battery Balancer (BMS012201000)

The Battery Balancer equalizes the state of charge of two series connected 12 V batteries, or of several parallel strings of series connected batteries. When the charge voltage of a 24 V battery system increases to more than 27 V, the Battery Balancer will turn on and compare the voltage over the two series connected batteries. The Battery Balancer will draw a current of up to 1 A from the battery (or parallel connected batteries) with the highest voltage. The resulting charge current differential will ensure that all batteries will converge to the same state of charge. If needed, several balancers can be paralleled. A 48 V battery bank can be balanced with three Battery Balancers.
