So I decided to run an older Chinese laser module straight off 2, 3.7V lithium ion batteries in series without any power supply. The power output majorly increased from 3.8 watts to 5.4 watts(Yes I have an LPM).
Though the module obviously gets hot much quicker, I haven't had any problems so far whatsoever after hours of run time(Of course not running much more than a minute per session). Everything seems fairly stable and the power output continues to stay the same.
So what's the big deal with using a PS/driver? As long as your batteries are supplying the right voltage and current it should be okay right?
