Thanks everyone for the thoughtful replies. I'm very hopeful that the
problem is something external that I have control over, rather than
internal, which I don't. I'll be putting lots of attention into that
terminal, strap and hardware tomorrow. It will be embarrassing if it
turns out to be som
Thermal imaging is amazing!
I was playing with one in the basement, looking at pipes and then I saw a
big white spot in the area of the stove up in the kitchen. Worring that
something was wrong (no heat source should be there) I ran upstairs to
find a cat asleep on the rug in front of the stove.
If you had a proper BMS like the Elithion system that I have, it would
show you the exact temperature of each cell and warn you of over
temperature.

Yes. Heat is going to conduct better through the metal plates of the batter vs
the electrolite. Therefore, the heat if generated at the connector is going to
conduct along the metal plates. Assuming that the plates in that battery are
vertical, I would expect something similar to what is bein
Wow, hat's a great observation. Question: is it significant that the IR

uniform ?

Carefully check the connection on that cell tha
I have always thought temperature could be used in this way.

I had a loose connection on my pack. It heated the cell to failure before I

I agree with Marco that it is quite likely a dirty/corroded connection
between the strap and the cell. This is more common than most folks realize.
Remove the strap. Clean both surfaces with Scotchbright. Apply a thin
coating of NoAlOx to the terminal and to the bus bar. Reassemble.
