Victron EnergyVE.Direct Smart Dongle (Bluetooth) - Wireless Data for BMV & MPPT - View on iOS & Android with VictronConnect App

Useful addition for the Victron MPPT controller to enable efficient battery charging based on voltage and temperature.By measuring voltage at the battery bank terminals, errors arising from voltage-loss due to cable resistance are avoided - guaranteeing the correct charge-voltage. For lead batteries, battery temperature data is used to adjust the charge-voltages: cold batteries require an increased charge-voltage, whereas hot batteries require a decreased charge-voltage. For lithium batteries temperature data is used to disable charging when they are too cold: charging lithium batteries near or below freezing causes permanent damage to the cells.No additional wires needed between the two unitsVery easy to set-up and connect to both the app and the Victron MPPT via their VE.Smart Networking:1) Start by connecting to the newly installed battery sense in the App (it will automatically suggest to update firmware if required (If you have an active 4G or WiFi on your device).2) clicking on the cog and the VE.Smart Networking allows you to either create or join an existing network3) If MPPT is not already on a network, you then just go back into the MPPT controller, to the cog icon then to VE Smart Network and then join this product to the network.Hey presto! all done!No issues with the Bluetooth range and you are left with a tidy setup

Great wee gadget. Very easy to install and use. Gives you great information on what's going on with your power.

Great functional addition to the Victron Blue solar range. This range doesn't have bluetooth inbuilt. This dongle allows this functionality. East to install and comes with a long lead

I liked that there is clear instructions provided. Temperature and Voltage values are added to the Bluetooth Network App. Although the voltage is already given in the solar charger information, which on my set up is the same.So for me the only thing it brings to the party on my set up is the temperature reading.It would be better if there was a battery charger % indication, which I was hoping for. I guess Victorian want me to spend even more money to get that.

Expensive but works.

Very good range much better than standard 👌

Easy to install on a motorcycle, voltage matches what a multimeter reads.However - no onboard storage so every time you connect to it you're left with a big gap in your graph. A lot of the very cheap competitors on here seem to store a month's worth, but I wanted the peace of mind of a reputable brand and a reputable app.Edit - I was wrong - it does store previous measurements, the app was just behaving a bit funny but it works perfectly now.

Having lost a pair of batteries in my Land Cruiser when the Alternator went on the frizz I wanted to make sure that the charging system and new batteries and alternator were all working ok. The Sensor was simple to install as the eyelets bolt directly to the battery terminals. Once I connected the Victron Connect app on my phone to the Sensor, the app immediately downloaded new firmware for the Sensor. It rebooted and connected to my phone app at once, displaying the voltage and temperature of the battery (or pair of batteries in my case).I've included a screenshot showing the background voltage of my batteries (12.7v ie 100% charge), the voltage dip as the starter motor turned the engine over, and then the initial charge voltage when the engine started, a perfect 14.2v from the new alternator.Exactly what I needed to know, everything is working perfectly in the LC.The story doesn't end there. I also have an old campervan and I'd like the same confidence in its charging system and starter battery, the battery being at least 6 years old. My solution was to buy some industrial velcro on Amazon and put the bluetooth sensor in a tight pouch of female velcro. With a strip of male velcro stuck to the top of the battery, the sensor can be moved from vehicle to vehicle as required, once unbolted of course.
