Unfortunately it seems me and little boards do not seem to get along that well. Perhaps my soldering skills or my attitude needs some improvement. I killed one of George's VIP 750 boards and now I killed a GD1000.
Enter the Micropuck SHO.....500mA of guilt free power in an incredibly small package. However, for the solder challanged, it's perfect.
On it goes to a heatsink, although not necessary, I epoxied it to the bottom of the heatsink. Put it into a 4 D M@glight with 4 Accupower Evolution 10,000mAh Low Discharge batteries and topped it with a Cree Q5 (I forgot how dissappointed i was with the Cree vs. the bright white Seoul P4).
It has been 5 full hours and the thing has not dimmed, not gotten hot, it has just plain been running incredibly well. I need to switch it to a Seoul and compare it to my other Seoul lights to see what differences in brightness I can see.
LESSON LEARNED: If you want a simple way to mod a flashlight with zero soldering skills needed, use a Micropuck that has wonderfully long lead wires.
LESSON LEARNED #2: If you need extreme runtimes, use NiMH D cells in a 4 D flashlight (Yes I will throw this together with some Emoli "big" batteries and see what happens, the Micropuck takes 4 to 8VDC as a buck driver, so I hope resistance in the M@glight eats up the say 0.2VDC that my Emoli have when charged to 4.1 VDC)
If 2 Emoli batteries will work, then a cutdown 3 D should be a perfect host for them and it will be interesting to see how long the Emoli batteries last compared to the 4 Evolution D cells. If I can get the good runtime, how incredible would that be?

At 500mA and around 3.25V, with an efficient buck driver and four 10Ah NiMHs, I'd be surprised if you got less than 20h.
