I see your discharge/temperature graphs handle up to 50° ΔT. What is your cell temperature cutoff? Is it absolute or relative? Seems relative absolute to me, to ≈75°C. Is this right?

Cheers :-)

Yes, I started at 85°C, but have adjusted it down due to melted battery holders.

Keystone make an aluminium 18650 / 20700? holder. Might not work well as a test fixture.

I need the 4 terminal connection and it is inside the plastic connection it melts.
