ShockLi IMR 18650 3100mAh

Hi,

I am interested in the ShockLi IMR 18650 3100mAh battery. I just wanted to know if anyone has this battery, and what if it is everything it claims to be?
I am wondering if it can really do 40amps continuous max discharge?

18650 & 21700 battery internal resistance cold testing

edit 23.1.2019: added 18650 results at the end of the post

Many people report that lights can’t sustain their turbo modes in freezing temperatures. I tested four 21700 batteries and one 18650 after they had been outside in (-12°C) for an hour. Their surface temperature was at -1 to -3 degrees Celsius when I started the internal resistance (Ri) measurement. The test was done inside. I did a similar test previously on some 16340s.

What's under the wrapper (Sofirn + Thorfire 18650s)

Decided to remove the wrapper from some of my Sofirn and Thorefire branded batteries. I did a search and found speculation as to what was underneath but not definite answers.

Three different batteries (all buttontops)
-Thorefire 3000mah protected 18650 (came as part of a Thorefire C8S kit with batt and charger)
-Sofirn 3000mah unprotected 18650 (purchased from AX seller E-battery Store)
-Sofirn 3400mah protected 18650 (purchased from AX seller E-battery store)
