Then I have no idea why they don't work like they're supposed to. If you've wired them correctly (like in the picture and the battery+ to the center of the bottom and battery- to the outside), and with an 18650 the boards should work.
You know that switching modes is just a little press on the switch, right? Very quickly off and on.
The only thing I can think off, is that these boards aren't programmed correctly. I have read in a thread here that that can happen.
When did you receive the boards?
