The Victron BMV battery monitors are highly accurate, incredibly easy to install, and very reasonably priced. The BMV-702 monitors multiple parameters for one battery bank via a 500 amp shunt. In addition, it will read midpoint voltage from a multi-battery bank, or the voltage of a second bank, usually the starting battery. Since there are inefficiencies in charging, and variability in the power available from the battery depending on the rate of discharge (Peukert's law), the monitor performs sophisticated calculations to correct for these factors. * * * Installation is a snap. The monitor display comes with both a round and square bezel, and fits a 52mm (2-1/16") hole. The shunt attaches between the battery and the ground connections, and a provided network cable connects the two. * * * An improved menu makes navigating the display easy. Displays include: battery voltage, real-time current, consumed amp-hours, state of charge, time to go, and with the second connection, either a battery #2 voltage or midpoint deviation of the main bank. There are also user-programmable alarms.

The only issue I have is that I have a two battery bank that are wired independently (not in a string) so it only gives basic monitoring of the second battery ( voltage reading). I still give it a five star rating as this unit is very useful, very accurate and gives me real time monitoring of my battery health. I am thinking of buying another unit to have the full array of monitoring of my second battery.
Great instructions and fairly easy to install. (Full disclosure: I have an advanced engineering degree)
One gripe/request: the app should show time until full charge, which I could have sworn it used to but doesn't with the recent update.
