The BMV-712 Smart is 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 are needed.
Also included is 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.
A Battery Balancer is recommended to maximise service life of series-connected lead-acid batteries.

Very low current draw from the battery
Current consumption of the BMV: 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.
