How is everyone attaching cell temperature sensors?

I am using LG pouch cells (from a Chevy Bolt) and Barium BMS.

I was thinking of using hot glue at first, but realize that is likely an insulator.


How about something like this:

How about something like this:

I used that kind of heat sink plaster. And then i have covered the opposite exposed side of the sensor with packaging foam so that it only gets into contact with the cell side.
 
These are pouch cells preassembled in a frame/support, I can't really get to the side of the cells. So I'll be attaching the sensors to the end tabs/terminals.

6 sensors in total. 3 for each 14s pack.
They are small bulb(?) sensors.
You can see two of them in this image below the shunt.
 
The terminal end works with maybe one on the side on the center of the pack.

Later floyd
 
I'll be stacking 4 packs, so I can't use the sides as there will be another cell block right on top.

The terminals are copper and go straight into the cell. They should be the same temperature (or close to it) from the center of the cell to edge where it connects to the next cell.
