I finished a build today for a friend. His module is an 800mw or .8w, 445nm that calls for up to 7.5v power supply. So I opted for two of the 18650 li-ion cells. Whic is a 7.4 pack. Now Im starting to worry about wheather or not that was such a good idea. That 7.4 s nominal voltage, right? They are like 8.4v charged up good and hot arent they? Should I instruct him not to firethe LASER until I can install a resistor or two in line?
