Smart Battery Sense, Voltage and Temperature Sensor, Long Range (up to 10m)

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 units Very 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 network 3) 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

This is the second one of these I have purchased, one for my caravan and the other a camper van. Both work perfectly and allow one to keep track of your battery’s state of charge over extended lay ups. They also effortlessly connect to my other Victron accessories via the free Victron Connect App. One minor criticism is the size of the ring terminals fitted, they are huge! However easy enough to snip them off and replace with, in my cases, a 6mm ring terminal.

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.

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.

Works great stops the lithium batteries charging below 5 degrees.

Brilliant product.

Wow this solved my issue of the solar controller thinking my lithium battery was full due to the caravan wiring and backing off the solar input. Very easy to set up on the Victron App small and inexpensive.

Works very well
