I agree, the problem is in the tailcap. I had my MTE SSC P7-C for about six months, when it started flickering. I opened up the switch, sprayed WD-40, and the problem was fixed. Three months have gone by, and the problem has not recurred.

I agree with the last two posts. I had to fix the head after cutting a wire in error, but the improvement was in the tail cap. There is a PCB with a copper circle around the edge that was not making contact with the disk in front of it. I had to get solder flux off of it and lower a few high points of solder so it would make better contact with the disk. After that a a good light.

Yes I know, this thread is old.
But this bugs me.
How do you get 3 Amps?
I only get 1,8A with a 18650 at 4,1V

Some of the early MTEs have a trio of dropping resistors which limit the current to ~2A. Many CPF members just short them out to get direct drive.
Many of the early 18650 cells are 1600 mAH and are in the explosion danger zone when pushed to 3A.
Also that is a small torch. Running in direct drive can make it too hot to hold in 15 minutes.
