Battery Monitor BMV-712 BLACK Smart - 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. 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. 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.
