The Victron Energy BMV-702 is a high precision battery monitor. The essential function of a battery monitor is to calculate ampere hours consumed and the state of charge of a battery. Ampere hours consumed are calculated by integrating the current flowing in or out of the battery. Features of the BMV-702Battery ‘fuel gauge', time-to-go indicator, and much more The remaining battery capacity depends on the ampere-hours consumed, discharge current, temperature and the age of the battery. Complex software algorithms are needed to take all these variables into account.Next to the basic display options, such as voltage, current and ampere-hours consumed, the BMV-700 series also displays state of charge, time to go, and power consumption in Watts. Bluetooth Smart Use the Bluetooth Smart dongle to monitor your batteries on Apple or Android smartphones, tablets, macbooks and other devices. The BMV-702 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 (10m) and battery cable with fuse (2m); no other components needed.Also included are a separate front bezel for a square or round display appearance, a securing ring for the rear mounting and screws for the front mounting. Easy to program (with your smartphone!) A quick install menu and a detailed setup menu with scrolling texts assist the user when going through the various settings.Alternatively, choose the fast and easy solution: download the smartphone app (Bluetooth Smart dongle needed) Standard features of the BMV-702Battery voltage, current, power, ampere-hours consumed and state of chargeRemaining time at the current rate of dischargeProgrammable visual and audible alarmProgrammable relay, to turn off non critical loads or to run a generator when needed500 Amp quick connect shunt and connection kitShunt selection capability up to 10,000 AmpsDirect communication portStores a wide range of historical events, which can be used to evaluate usage patterns and battery healthWide input voltage range: 6.5 – 95VHigh current measurement resolution: 10 mA (0.01A)Low current consumption: 2.9Ah per month (4mA) @12V and 2.2Ah per month (3mA) @ 24V BMV-702 additional featuresAdditional input to measure voltage (of a second battery), temperature or midpoint voltage, and corresponding alarm and relay settings. Other battery monitoring options Lynx Shunt VE.Can More about midpoint voltage 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 batteries. Looking to mount the BMV-702 Smart, why not purchase the wall mount.
