I have a couple of MT-G2 direct drive P60 dropins. These Kinoko 18350’s work perfectly providing about 5 amps without killing the led. AW’s 18350 killed one in about 5 seconds. So maybe a little internal resistance is a good thing sometimes. I bought eight of these about a month ago and have been very happy with them. I’ve run a few to cut off and they do hold voltage close together to the very end.
