BMV-712 Smart Battery Monitor with Shunt - 6.5-70 VDC - Display, Bluetooth and Detailed in-App insights- Grey

Great bit of kit ~ value for £ and good delivery time

Easy to install, and works perfectly, data cable is very long and in my case I only needed about 4’ so it means a large bundle of cable in battery compartment so I’m looking for a shorter cable which would be great if this was an option on purchase, apart from that I’m happy with it

A great improvement on our previous method of working out what our batteries were doing. Not easy to fit, and not a staightforward job with a lot of adjustment needed to the wiring layout in our case at least. Having got through it and installation complete, I would be without it for its clear information on what our charge state is.

I had this fitted during a narrowboat battery replacement. It was a surprisingly simple installation. Once in, the unit worked first time (including Bluetooth app and link to starter battery) and I am now officially obsessed with the state of charge of my batteries. To the point of ad nauseum!

I do not think the display provided is worthwhile so I did not install it so it was visible. Luckily the telephone app is good and reliably connects over Bluetooth over a fair distance. The only disappointment with the app is that it only records whilst it is active and the information is lost when you leave the app. Because the negative connections are in my case many and smaller than the victron connection you need a go between such as a “bus bar” but I used a connection piece that connected to the victron but had two smaller connections. I also needed to purchase a battery cable. As well as the connection to the leisure battery I was going to add the connection to the starter battery but have not done so yet as it is difficult to route a cable to it.

This was part of a new battery installation on my boat, fitting and setup was incredibly simple and everything worked perfectly 1st time. Shunt is in a particularly difficult position in my installation so I pre programmed everything before installing it physically. It all networked easily with the other Victron components and immediately after switching on, the new charger was using information from the BMV-712 in its charging profile. Excellent piece of kit, I do however recommend using the app from Victron as it is much easier than scrolling through the menu on the little screen. Would definitely recommend this.

After installing a brand new expensive AGM battery bank in my camper , I was at my wits end for a few weekend trips worrying about keeping my state of charge above 50%. When I installed this it gave me peace of mind. I don't know what the other reviews are fussing about Bluetooth coverage for.....I have no problems....i can check it from GREAT distances. It can be tricky to get connected at the start, but bear with it and keep trying and checking you're doing everything correctly, because when you do , you won't believe how accurate and functional it is. Highly recommended quality product.

Easy install, works straight out of the box without faffing, great product

Vraiment très pratique pour le surveillance d’un système de batterie dans un camping-car. Il est ainsi possible de surveiller les paramètres des batteries cellule et de la batterie porteur. Ces batteries peuvent être de technologie différentes (lithium / plomb) sans que cela pose de problème. Enfin grave à l’application et à la connectivité Bluetooth toutes ces informations sont disponibles sur son smartphone, un vrai plus

I’ve been running a full Victron setup in my RV since 2021, including the MultiPlus inverter/charger, the SmartSolar 100/30 charge controller, the BMV-712 battery monitor, and the Digital MultiControl panel. After years of use across various climates and conditions, I can confidently say this system has been absolutely rock solid. Each component was easy to install and configure, and the integration between devices is seamless. The MultiPlus handles all of my AC needs flawlessly, switching between shore power, generator, and battery without a hiccup. The SmartSolar charge controller keeps my solar system optimized and running efficiently, even on cloudy days. The BMV-712 gives me precise battery monitoring at a glance, and the MultiControl panel makes managing the inverter simple from inside the RV. What I appreciate most is how this system has given me real freedom. I can boondock for days without stress, knowing exactly how my batteries are doing and trusting that the system will just work. It’s added reliability and convenience that truly changed how I RV. Highly recommend Victron to anyone serious about upgrading their mobile power setup. Worth every penny.

Foolproof robust Battery condition readout with Bluetooth functionalities. You can not go wrong . In my case for Lifepo4 Battery bank 4x paralel 12V DIY Camper.

Das ist ja ein cooles Teil. Präzise kann man hier den Ladezustand des Akkus beobachten, entweder per Display oder App. Einzige Kritik: es sollte besser beschrieben werden, wie die vielen Parameter für den verwendeten Akku-Typ einzustellen sind. Ich kenne mich doch nicht aus- welchen Wert für Schweifstrom oder Peukert-Exponent. Da gibt die Anleitung nicht viel her, das Internet hilft dann aber. Wenn es einmal eingestellt ist, liefert es beste Ergebnisse.

Works with my mppt solar controller via single cable But you need to buy this VE direct cable separately Gives you data and fine tuning options for charging via solar controller Latest display unit as well Overall it's a great buy
