Hey guys, 100% new here, but I’ve got something fun that I’ve been working on for a little bit.

Single cell 18650 XHP50/XHP70 driver. Features include:

2.7-4.2VDC source, 6VDC output.

Low Voltage shutoff @ 2.7VDC

17mm Driver board size.

Should be 3A Constant Current.

Right now it is a 100% functional proof of concept, heat as you all know is what my next “job” is, it will run for as long as I keep the battery connected, but I have limited it to <30s. It is my first completed board, hand reworked 0201 packages. It sucked. So I don’t want to burn this one out (if it is destined that way).

I’ll add pictures and a video to youtube. No there is no trickery. Just though you would all enjoy it!
