I don't pretend to understand you guys tech speak, so I will wait for the layman's results, but I am glad this is being done. Thanks guys.
Maxing out the batteries and testing their max C ratings will give us much more information about their capabilities, failure thresholds and max temperatures achieved.
I disagree, it is only warm to the touch at 106F. My body temp runs about 99F, which is warm. Yes, battery life is cut down, but, my concern in testing isn't overall battery life, it's safety. Thermal runaway doesn't happen until 200+F. For example, Panasonic list the thermal runaway temp of their batteries at 212F.
We don't manufacture the batteries, we just test them so all we can say is our testing of a particular batteries output will meet the demands of X device. If you want someone to make legally binding statments for a particular C rating, you'll have to bring the manufacturers in like Panasonic, Tenergy etc....
AW LiFePO4 3.0/3.2V 16340 Results
AW's Listed C rating: 5C
I subjected them to max load ratings, way beyond what our ecigs draw. I tried to get 4 of them to fail by subjecting them to a 10amp continuous load (20+watts) and draining them down to zero volts. They reached 180F, but none of them failed or leaked.

So here is the problem....earlier you said that the cells are good for "10c", but you won't back that up with a legally binding statement. You just differ to the manufacturer. There is the problem....you can't say it's good for 10c and then not be willing to take some accountability for that claim....
So in reality it's possible to get 10c (we all know that is true), but no one will back that up with a legally binding statement about "safe at 10c"
I was under the impression that the purpose of the thread here was to get legally binding endorsements about specific batteries. I can see we aren't ever going to get there. Pity....
