I found out the hard way that 3 AAA batteries is not going to fly for these diodes, especially with the micro flex drive cranked up all the way. Not enough juice. I came up with a last minute solution that saved the build, and make a kick-ass powerful laser out of that silly little 9 LED host. I reconstructed the 3 AAA holder from a series to a paralell by bridging the connections at the top and bottom, and attaching the single spring from the top, to the bottom so all 3 springs are on the bottom. I also added a pcb that came off a protected 18650. It was meant to be connected the same way, on the bottom where the spring in the cap with the clickity switch contacts. Now it will take 1-3 10440 lithium cells in paralell, and has a protection circuit to prevent overdischarging the batteries. This was actually pretty simple to build, it tool just a few minutes. The end resault was great, it was just as good as if it were powered by a 18650, just doesn't have quite the capacity is all. And it's a really compact unit, in the little 3 AAA host.
