4w 445nm 14500 Mini Laser Pointer

I have successfully finished prototype of my 4W mini laser.
This is a C3 chinese flashlight host, with custom brass insert like all my other lasers (jlasers.org)

It uses a 3.7v 14500 li ion battery and pulls a whopping 6A !
The boost driver on this thing is insane..

I was able to get 4W out of this guy even with a cheapo acrylic lens!
This little guy only weighs 115g.

I will sell them soon on my store in the coming weeks when I receive my drivers from the PCB manufacturer.
