How to connect the temperature sensor

Hello all,

I have the branded temperature sensor from victron. I am currently figuring out how to connect it to my battery bank. I currently have 4 batteries in series. I have the victron 702 monitor.

Now, in the manual, I see that I am support to replace the two probes with the temperature sensor. I do that and place the temperature sensor on the most positive terminal. When I do this, I lose my voltage calculation and the midpoint and I do not get a temperature sensor reading.

So I am coming to hte community here. What is the best way to connect the temperature sensor to a bank of 4 batteries?

Hi @phillip mobley

It's either measuring a second battery voltage, midpoint voltage or temperature for the auxiliary input of the BMV-702. Please check section 3.6.3. Auxiliary connection for temperature monitoring in the BMV-702 manual.

Make sure you have the correct sensor, the one for the battery monitor is model number ASS000100000 (5 zeros at the end).

The other type, model number ASS000010000 (4 zeros at the end) will not work with battery monitors.
