So today I got my laser and I was ecstatic to pop in my freshly charged 3.6v (running at 4.2v, that's a .6v increase over stock batts that charge up to 3.6)batts and get ready to go. I tried burning stuff, but it was horrible. It couldn't go through a cd case, plastic, and it barley popped balloons from 1cm. So i was like "wtf This dilda should be running around 250mw with 2x 4.2v batts and hand picked form o-like." Then I realized that maybe I was focusing it wrong. I left it on what appeared to be the smallest dot from 20feet away, but I didn't realize that I should change it when I'm burning stuff 1ft away. So I got 1ft away and omg stuff just started smoking up on contact and it was crazy.
