The Victron Energy BMV-702 is a high precision battery monitor with the essential function to calculate amp-hours consumed and the state of charge of a battery. Amp-hours consumed are calculated by integrating the current flowing in or out of the battery.

Product Features

The BMV-702 LiFePO4 battery monitor is highly accurate, incredibly easy to install, and very reasonably priced. The BMV-702 monitors multiple parameters for one battery bank via a 500 amp shunt. In addition, it will read midpoint voltage from a multi-battery bank or the voltage of a second bank, usually the starting battery.

Installation is a breeze. The monitor display comes with both a round and square bezel and fits a 52mm (2-1/16โ€ณ) hole. The shunt attaches between the battery and the ground connections, and a provided network cable connects the two.

An improved menu makes navigating the display easy. Displays includes battery voltage, real-time current, consumed amp-hours, state of charge, time to go, and with the second connection, either a battery #2 voltage or midpoint deviation of the main bank. There are also user-programmable alarms.

Now you can even connect your Smart Phone to the BMV-702 LiFePO4 Battery Monitor to view BMV or MPPT information on iOS and Android devices with the help of the Bluetoothยฎ Smart dongle and application (not included).

Tested and approved for use with Battle Born Batteries.

Features

Bluetoothยฎ Inside: With Bluetooth ยฎbuilt-in, the BMV Smart is ready for the Internet of Things (IoT) era. With Bluetoothยฎ being implemented in most other Victron Energy products, wireless communication between products will simplify system installation and enhance performance.

VictronConnect App: Use a smartphone or other Bluetoothยฎ enabled device to:

  • Customize settings
  • Monitor all important data on single screen
  • View historical data
  • Update the software when new features become available

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: RJ12 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. We recommend a Battery Balancer to maximize service life if you’re utilizing series-connected lead-acid batteries.

Low Current Draw from Battery: Current consumption of 0.7 Ah per month (1 mA) @12 V and 0.6 Ah per month (0.8 mA) @ 24 V. 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 100 Ah battery capacity. The battery will be damaged if the remaining capacity reserve is drawn from the battery. A residual current of 10 mA for example may damage a 200 Ah 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.

Other 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 โ€“ 70 V
  • High current measurement resolution: 10 mA (0.01 A)
  • Additional input to measure voltage (of a second battery), temperature or midpoint voltage, and corresponding alarm and relay settings
