Thermistor question

[andreweb1]

This should be a simple answer but..
I am using an xlr connector for charging.
What should the circuit be for putting the thermister in a 36v nimh pack?
Where is the best place for the thermister to go?
Thanks

The thermistor should be taped/glued/etc to one of the cells in the pack, preferably in the middle of the pack where it will get hot when the pack nears full charge..

The 3 pin conector usually has .. +(red) -(black) and Temp(yellow)

Thanks. The thermister, goes to yellow from the positive tag?
