I use two of these to hold my 18650 lights: http://www.dealextreme.com/p/univers...cle-mount-8274

The light I bought from dealextreme only lasted a few months, but these are still holding up years later.

And to make it easier with two lights, I currently have them mounted on one of these: http://www.minourausa.com/english/ac.../sg300s-e.html

I also use the $7 charger a1 posted, but the dealextreme batteries eventually died. I bought some 2400mah batteries from Solarforce and I've never had to worry about them.
