Here is a picture of the mods I did this last week I don't think any of
them took me more than 45 minutes to put together. On the left is my 10 dollar chuck, I put this one together with a cheap flashlight a radio shack switch, a scavenged 510 battery connector and last but not least a little "Billy Mayes" wonder putty. That one takes a 18650 or two 16340 ultrafire protected batteries. The one on the upper right takes 3 off the shelf nimh AA rechargeables and the lower right is the standard nico stick with one 14500 ultrafire protected.
