Good job with that 18650 modification...

Remember that most 18650 batteries have a flat positive end, so you want to build up a little solder mound on the 3405 positive contact board at the bottom of the pill because the board is flat on these 3405's...

I am definitely going to do that for the best contact I can get. But my AW's do seem to work fine with the small bump that is in the host now. The AW's have the most recessed positive of any of the 18650's that I have.
