VICTRON Battery Monitor BMV-712 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: RJ 12 cable (10 m) and battery cable with fuse (2 m); no other components 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. Please see the BMV manual, section 5.2, for more information.

We recommend the Battery Balancer (BMS012201000) to maximize the 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 shut down 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 a discharged state for more than 8 days.
