Victron Energy Temperature Sensor for Victron Energy BMV-702/712

I was adding a shunt to know my charge level on my travel trailer batteries and found this option to include temperature. The product arrived quickly, was easy to install, and works as expected.

Works great. Be aware that you need to splice the wires of the temperature sensor into/with the sensor wire of the 300 amp shunt. I think it plugs in directly to the bigger shunts. Don't know for sure about that

Very easy to install and works great. The wires are very sturdy. Only took a few minutes to put on. Seems like excellent quality but a little pricey.

There are no problems with these sensors, in general, but the one I received had a blown fuse in it. I had a spare 1.0 Amp fuse from another connector wire that came with my 712 Smart meter, and the sensore worked immediately. It was quite a surprise when it did not work first time. I am willing to bet this was a return by someone who does not know about fuses.

If you have a SmartShunt and want to keep track of the temperature near your battery and send it to VRM then this is a handy item to have. It includes a heavy duty lug and connection to the IP65 SmartShunt 500A was relatively easy. For my connection I simply split the red/black wires, removed the red wire at the fuse then used my existing connected red wire on the shunt to connect this lug, cut the grey wire ring terminal off the shunt and tied it into the black wire on this sensor. But for what this is, the price is a bit up there and that leaves a little bit of a bad taste in my mouth. The temperature sensing is also taking place near the positive battery terminal which could be a good thing for high temperatures, but could be a bad thing for detecting LOW temperatures as that area is more likely to be a bit warmer than ambient air, especially if you're pushing a decent amount of current. I don't expect it to be a huge problem as you can set your charging cutoff voltage a little higher and the cells will be inside a case likely being warmed up so it may all equal out in the end. Considering the low cost of temperature sensing, it would be nice to see sensors integrated into more Victron equipment directly or having ports for a simple NTC to be plugged in allowing you to monitor whereever you want.

This item works well with my Victron Energy Smart Shunt. I just followed the instructions and plugged things in and I have my battery temperature at my fingertips!

Except for no specific instructions on the best way to splice this temperature sensor into the existing wires. It was pretty straightforward.

This is the second unit I got on Amazon. The first was from Pike Industries The unit not only didn't have a fuse holder, it didn't provide +v to the shunt. Pike Industries didn't answer my questions.I was told by Victron to contact Pike. That is not typical, I suspect maybe it was a knock off.The new unit looks like an actual Victon product that was sold by InvertersRUs. It came with the required fuse holder and works as expected.
