Victron EnergyBMV-712 Smart Battery Monitor with Shunt - 6.5-70 VDC - Display and Bluetooth - Grey

Very easy to set up. this is an expensive accessory with cheaper option on the market. but the Bluetooth and quality make this one stand out. It is real nice to be able to make adjustments on my phone and monitor the batteries without scrolling though the readout on the display. The Victron app in easy to use. In addition. This meter also comes with a longer data cord then the cheaper battery monitor kits. I mounted the display with the other camper controls which are in the opposite end of my 25' trailer from the batteries that are mounted on the tongue. It was nice to not have to track down a longer data cable and have the extra cost.

I installed this battery monitor in my RV. Victron makes great stuff and this monitor gives me all the information needed to monitor my 300 AH Lithium battery including State of Charge, AMPs going out, hours left at current rate, and much more including history and trends. Much better than the inexpensive Chinese monitor I installed on my sailboat. I'll be upgrading that one soon.

Have bought two before for previous RV's and boats.All worked great

Arrived on time. Pretty easy to install. Bluetooth works well.

Compact and reliable. Used to monitor aH in motorhome couch batteries

Easy to install and setup

I have tried several cheaper battery monitors, but they all lack the features to accurately track a battery's state-of-charge. I decided to try overpriced Victron units because of the excellent reviews. These stand out because they are relatively easy to set up and have all the parameters needed to accommodate for losses in the charging and discharging of the battery.Positives:1) Accurate, once properly programmed.2) Good Bluetooth range. The BMV-712 unit has the Bluetooth circuit and tracking logic in the meter itself which can be located a good distance from the shunt. They supply a very long cable which allowed me to locate the meter on the other side of the garage, close enough to the living area to provide a good signal in my office a couple of rooms away.3) Decent, but limited App.Negatives:1) Expensive. Victron products are way overpriced.2) You can view the real-time and historical (trends) data in the App, but there is no option to download the data. Seems like it would be a very simple feature to allow downloading a CSV file.3) The display is small, cheap plastic and not very visible. Since I got it for the Bluetooth, this is not a real problem for me, but it might be for other applications.4) Can't access through a PC, so you are limited to your phone.
