Victron EnergyBMV-702 Battery Monitor (Black)

Although installation requires very heavy wiring as needed by the battery circuit that it is monitoring, setup of the remote display is very easy. Appears to be very accurate for discharge and charge reporting in the single 100Ah battery loop it is installed in. Easy to follow instructions.

This is a must have for an electric boat so you know how much power you have used and have left. Easy to hook up and you will be mad at yourself for not doing it sooner.

This has got to be my favorite piece of equipment on the boat. The accuracy of this unit is amazing. I tested this by watching the amps that were being drawn from the batteries with my original standers bulb running lights on my sailboat. I then swapped the running lights to all LED. It went from drawing 1.5 amps with the old lights to drawing 0.25 amps with the new LED lights. I performed this test with many of my electronics on the boat and compared the readings with the specs for each peace of equipment and this thing is accurate to the fraction of an amp,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.

BMV 702 stopped working a couple of weeks after installation. Has B+ voltage at the shunt but unit won't power up.

easy to install

If you have a camper/RV with a house battery based electrical system, you need this tool. It tells you exactly how much current is being drawn and what the condition of the batteries are. A fantastic tool and very easily installed.

The meter did everything it advertised and was fairly easy to install. The hardest part was routing the wire. My only criticism is that I wish the numbers were a little bigger.

Well after just 2 yrs the shunt is broken. Not only did it rust pretty fast inside my storage of our motorhome, but the cat 5 connector broke right off. What's even worse is getting a hold of victron to replace just the shunt. Left emails and after a few days all I get is a link to some other company that might be able to help. When talking to the other company, they did not really know what I was talking about. They said we will call you back within a few hours, that was a few days ago. Anyone know of a different shunt or monitoring system out there that stands behind their product? We are fully off grid and need one fast.
