I was seaching the net for lithium batts last night and found that the
lithium polymers are in production and available for Nokia cell phones.
Not cheap, $89 for 3.7v cell that is about 600mah and weighs less than 10
grams.
There are a number of free plans for chargers that would only cost $10 to
$15 to build, but I remember seeing a site somewhere with a kit for about
that much.....
The Magellan site (magtech.com I think) has a $45 Li charger that is
reconfigurable.
I can't find the $7.50 800mah tadirans anymore, they were on the site with
the cheap charger kit which I have lost the URL for.
Anyway, I have some feelers out to MFG's for Li poly's and may be able to do
a group purchase if there is any interest.....
