Battery Monitor BMV-702

Features

Bluetooth® Inside: With Bluetooth ®built-in, the BMV Smart is ready for the Internet of Things (IoT) era. With Bluetooth® 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 Bluetooth® 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:
