Can you supply a URL? While I strongly discourage people from making up
their own Li-ion battery packs for their glider due to potential safety
problems, a _production_ battery pack with it's dedicated charger would
likely alleviate most of the concerns I have about using a large Li-ion
battery in a glider. I don't worry about the little ones in my PDA, cell
phone, or camera.


Sometimes Froogle doesn't find the same things on successive searches. Here
is an example of what I'm talking about.

Specifications:
- Rating: 14.8V == DOUBLE CAPACITY 8800mAH (8.8AH)
- Capacity : 132 WHR 16CELL
$149.00 @ LinkExpressPC

I think this style would be much more suitable than a laptop battery:

Essentially the same ratings and price ($169 with charger), it has a
standard output connector and a easier to mount shape. Google "external
laptop battery" without the quotes. There is a wide range of price and
power in this style. Something like this might be very practical for
gliders, though I still want to know more about maximum ambient
temperature and altitude allowed, and built-in safety features.
