[chbot] 18650 battery sources

[Andrew Errington]

Ok.  That's a good answer.

I haven't used 18650 batteries yet, so I am interested in what people are
using them for, how they are using them, and why.

I generally buy my prized Chinese artifacts from DealExtreme (dx.com).  I
have never bought 18650 cells, but in general I have had no trouble with
the company.

Good luck with your quest.

Andrew
