Victron Battery Monitor BMV-702 BAM010702000R

Warranty Option: Standard 5 Years Warranty
Sale price$302.00


The BMV-702 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-700 series also displays state of charge, time to go, and power consumption in Watts.

The BMV-702 features an additional input which can be programmed to measure the voltage (of a second battery), battery temperature or midpoint voltage.


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.

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.

Standard features:

Battery voltage, current, power, ampere-hours consumed and state of charge
Remaining time at the current rate of discharge
Programmable visual and audible alarm
Programmable relay, to turn off non critical loads or to run a generator when needed
500 Amp quick connect shunt and connection kit
Shunt selection capability up to 10.000 Amps
VE.Direct communication port
Stores a wide range of historical events, which can be used to evaluate usage patterns and battery health
Wide input voltage range: 6,5 – 95V
High current measurement resolution: 10 mA (0,01A)
Low current consumption: 2,9Ah per month (4mA) @12V and 2,2Ah per month (3mA) @ 24V

BMV-702 additional features:

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

Other battery monitoring options:

VE.Net Battery Controller
Lynx Shunt VE.Net
Lynx Shunt VE.Can
More about midpoint voltage:

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.
Victron recommend their Battery Balancer (BMS012201000) to maximize service life of series-connected batteries.
