Tord, thanks very much for carefully documenting the greater hazards of Li-Po 
batteries, relative to standard lithium ion batteries.  I always learn from 
exchanges like this, and your careful work on this most recent post has 
accomplished that.

The problems with standard (i.e., non Li-Po) lithium ion batteries remain in 
the same league as NiCad or NiMH battteries, in my opinion.  As with any 
device employing high-energy density material, there is substantial potential 
for an unfortunate accident.  This is not a reason to abandon their 
appropriate use.

I'm keeping my standard lithium ion battery, and I plan not to abuse it.  It 
is a risk I have decided to accept.  OTOH, the cautions you cite on Li-Po 
batteries, particularly those from the AMA, will keep me from owning one of 
those until the problems are worked out (if that happens).

Regards,
