I want to build a short green laser pen with a 150mw module and was wondering if I can run it with a single 10440 Lithium battery at 4.2 volts. If the voltage is too high, is it possible to turn the pot down a little to reduce power to the diode? Or will the higher voltage burn out the driver? I've been using this configuration with the 405 laser pens and really like the compact size. Any other thoughts on how it could be done?
