Thanks for your quick response.
I'm pretty confident that the IR gun is accurate, cause I've tried two with very similar results. Also, if the pack is too hot to touch, yet the sensor only reads 110F, that's definitely not right.
The sensor is snug, but it is having to fight through shoe-goo for its heat reading. It's not wide enough to go over a cell, so it has to fit between two cells in a pack. I'll rip the shoe-goo off between two of my cells and see if that helps. Of course, even if that helps it's highly less than practical.
I'll let you know what I find out.
Thanks again.
