My battery level just read 44% & my IQ was 54.
I unscrewed all the tubes and cap as I was in 18650 mode.
It now reads 64% battery and 84 IQ!
Seems a little sensitive to me.
I discovered that sometimes after swapping batteries, my IQ would be low and simply rescrewing the tubes and end cap raised it.
When I analyzed what I was doing, it became clear. If I was pushing as I screwed the tube or cap on, it would tighten but then would loosen up VERY slightly when the clearance in the threads allowed it to after I stopped pushing. If I PULL while screwing it on, it can't do this--it's at the tight side of the thread tolerances. Yes, it is sensitive to that.
