Phil,
This is wonderful to watch.
Thanks

If you are interested and have the time, there is a 75 min video from June
2010 about how LiFePO4 batteries really work.

Here is the description:

Jay Whitacre, a Carnegie Mellon professor with a joint appointment in
Materials Science and Engineering and Public Policy, gives a quick overview
of Lithium-ion batteries. Starting at the chemical level, he explains the
properties and mechanics of the battery which give rise to macroscopic
behavior, especially focusing on issues relevant to electric vehicles and
other high-power systems. He then fields questions about the batteries
themselves, ongoing research at Carnegie Mellon, and tricks for improving
long-term performance, such as pulse-charging and pairing batteries with
similar defects.
