Well I got a 10amp, 30v variable lab supply for Christmas! (early) It runs my laser pretty well as long as I keep the voltage at 24v... If I turn it up farther, the fire doesn't pop out when I turn it on. Im sure this is because Its only 11 amps at the most. Tomarrow, ill try it with the li-ions in parallel. (15 amps)
Does it draw more current if you turn up the voltage? I've been runing at ~ 24 to 26 volts with two big gell cells.
I'm getting ready to hook up 8 - 18650's in series. I figure I'll get voltage drop at near 15 amps.
well, its hard to tell, I think that it does try to pull more and the ps only allows it to pull 11 amps... so if the voltage is above 24v, the ps adjusts the power and causes it to drop to where its able to supply 11 amps... I am quite sure it will do more with the 18650s in parallel.
Reply #20 from NightStick says he has run his off 7 cells. I plan to use 8 because sure as hell, there is gonna be voltage drops and heat.

By the way -- here's the barrel and driver housing at present ------------ please excuse the mess on the bench ;D The driver will be installed into that alum housing under the barrel. Battery holders will be mounted to the sides.
