Would this work?

I have this module if I used this plug and cut the end of the plug off then put one wire on the spring and another on the module would the module work? I do not know if it works this way but lazerer says it needs 350ma which the plug has and I use 16340 batteries which have 3.7V so the plug also meets that requirement so would it work? :thanks:

Yes, but this one is cheaper, more efficient, and would probably last longer.
