Hi Guys,

This site really rocks. I've found lots of useful information already. I'm new here, so forgive me if I'm saying crap.

I'm about to try buy some 18650 batteries (http://www.dealextreme.com/details.dx/sku.5776) and was wondering if there was a way to connect them together in parralel to increase capacity?

Is this dangerous?
Do you know some good and easy battery holders that could do (better if can be found on DealExtreme)?
Ultimately, I would like to use those to drive 2 or 3 seoul SSC-P4 LEDs. Possibliy using this regulator: http://www.dealextreme.com/details.dx/sku.6190
Any advice?

I'm also looking for good heatsinks, but heaven't found good ones yet on DX. Have to go to local store and look-out for copper or such parts, looks like it's the best option.

thanks for your help
