Hello guys. I'm planning a new 445nm build and I don't wont to put money on a driver. I want to use an LM317 driver with an 1ohm 2 watt resistor. I don't want to power my laser from a pc's power supply because it is not stable and I have destroyed 2 445nm diodes in the past with this power supply. So what batteries can I use to power my laser? Can I use 2x 18650 batteries at 2500ma each (3.7 volt 4.2 full) or it will be two much and will destroy my diode???
