Victron Smart Battery Monitor - BMV 712 Bluetooth 

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.

- monitor all important data on single screen,
- view historical data, and to
- 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: 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 rear mounting and screws for front mounting.

Option - Battery Temperature Sensor

This temperature sensor can be used with the auxiliary port of the Victron BMV-702 or BMV-712 to monitor battery temperature. Overheating a battery can drastically shorten it's life, and monitoring your battery's temperature can let you take action to extend it's useful lifespan. It can also alert you to equipment failures, or the failure of the battery itself. An audible alarm can be activated when the temperature reaches a threshold that you set.

The BMV-702 and BMV-712 supports either a secondary voltage input or the temperature sensor, but not both.

All Victron products come with a 5 year worldwide warranty, supported by an international network of service points and dealers.

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. Please see the BMV manual, section 5.2, for more information.
We recommend our Battery Balancer (BMS012201000) to maximize service life of series-connected lead-acid batteries.

Very low current draw from the battery
Current consumption: 0,7Ah per month (1mA) @12V and 0,6Ah per month (0,8mA) @ 24V
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 100Ah battery capacity. The battery will be damaged if the remaining capacity reserve is drawn from the battery. A residual current of 10mA for example may damage a 200Ah 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.
