I was under the impression by your photo that it was
a 532nm Green Laser module and not a 405nm Violet
Laser module.

Do you have a link to the exact Laser Module you have or
want...

In any case at 50mW output don't forget to get appropriate
Laser Safety Goggles...

A 18650 battery is fine, but note that when fully charge, it will be supplying 1 volt over spec... which will result in added heat for your module. Make sure to operate a reasonable duty cycle, or you can always use a 1N4xxx rectifier diode to drop your voltage slightly, and introduce reverse polarity protection.

You should also check with a multimeter, but your RED wire (+V) should be constant to the brass 'case' around your diode. This means you'll most likely have to wire your host to be case positive... with the + side of the battery facing the tailcap.

i have looked, but is there a thread or tutorial anywhere which shows how to make the host case positive? the modules which have a spring attached at the base are these already wired to fit it a case positive host?
