BMV-712 Smart Battery Monitor 

The BMV-712 is the latest high precision battery monitor from Victron. The BMV-712 monitors voltage and current of a single battery bank and calculates power, state-of-charge and time-to-go. It also features an additional voltage input that can be used to measure an auxiliary or starter battery voltage, midpoint voltage or temperature with the optional temperature sensor. Data can be transferred to smartphones or computers with the inbuilt bluetooth module and external alarms can be triggered with the relay contact. 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.

Victron BMV-712 Smart Bluetooth Battery Monitor – Black (BAM030712200R)

The BMV-712 is a high precision battery monitor which is essential for calculating the Amp-Hours consumed and the state of charge of a battery by integrating the current flowing in or out of it.

Use a smartphone or other Bluetooth enabled device to:

• customize settings,
• monitor all important data on single screen,
• view historical data, and to
• update the software when new features become available.

EASY TO INTALL 

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.

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

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 – 70V
• High current measurement resolution: 10 mA (0,01A)
• Additional input to measure voltage (of a second battery), temperature or midpoint voltage, and corresponding alarm and relay settings.

In the diagram above, the negative of the Starter/Auxiliary battery doesn't use the shunt to get to ground/chassis earth so the shunt isn't monitoring the starter battery current drain, it's just monitoring voltage. (It's not the best way of illustrating the best application of the shunt use, you may want to design your system with the negative lead not connected to the shunt.  (You must make sure that they share a common earth point elsewhere). You dont have to route the starter battery negative all the way to the BMV shunt, just leave it as it is in its present location and connect the sensor wire to the positive pole of the starter battery to allow voltage monitoring. So long as both the ground connection (top) of the shunt and the ground connection of the starter battery share a common connection point (like the chassis of the motorhome) you're good to go.

LOOKING FOR A 12V LITHIUM BATTERY CHARGER ADD ARDENT 

DC-DC Charging For Lithium Batteries

Regarding DC-DC Chargers and solar controllers, you must change these to LiFePO4-specific models, which can charge your Lithium batteries to an entire 100% State of Charge.  **If you are charging from an alternator, you will need a DC-DC Charger that is designed to manage solar specific to lithium (LiFEPO4).

What is a BMV-712 Smart Battery Monitor ?

With the BMV-712, you can rely on precise tracking of your battery's remaining capacity. This advanced battery monitor considers variables like ampere-hours consumed, discharge current, temperature, and battery age. Its software algorithms work out these complexities to provide detailed information not just on voltage, current, and ampere-hours consumed, but also on state of charge, time-to-go, and power consumption in Watts. Moreover, the BMV-712 adds an extra input to measure a second battery's voltage, temperature, or midpoint voltage. These battery monitors require a shunt to be installed on the negative side of the battery terminal. The shunt measures the real-time voltage of your battery system as well as the current draw.

The BMV-712 monitors voltage and current of a single battery bank and calculates power, state-of-charge and time-to-go. It also features an additional voltage input that can be used to measure an auxiliary or starter battery voltage, midpoint voltage or temperature with the optional temperature sensor. Installation is simply a case of connecting the supplied shunt in the negative battery cable, mounting the monitor in a 52mm diameter hole and connecting the wires. An optional wall enclosure is available if surface mounting is preferred. 

Battery monitors do much more than just display the state of charge of your system. Your battery monitor also provides you real-time and historical information on voltage, power consumption, temperature, and more. This data allows you to make better decisions on how to optimize your battery usage and charging. Victron is a "go to" Battery Monitor especially when you are installing Lithium batteries. Easy to use - clear display and Phone App for even more details of Battery use. Built in Bluetooth for ease of programming and monitoring

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.

A residual current of 10mA for example may damage a 200Ah battery if the system is left in the discharge state during more than 8 days. 

• The shunt connects in the negative line to the battery.
• The left hand connection is labelled "Battery Only" and that should be the only connection to the battery. Everything else connects to the right hand terminal which is labelled "Load and Charger". 
• The socket is for the RJ12 connector that goes to the meter itself.  The supplied cable is 10 meters long (approx 30 feet) but  other lengths are available. 
• The two connectors with the orange tabs are for the temp sensor/power supply connections. 

One tip to remember is to make the connection to the battery last.  If you don't the other end of the power wire could come in contact with a negative connection and blow the fuse.
