Not really. The A123 Systems batteries are HD Nanophosphate
technology which is allegedly better than conventional Li-Ion and LiPO
batteries. Although commonly used in overpriced battery operated
power tools, there's really not enough field experience to predict
reliability and lifetime.

Sounds a bit vague to me.
Fast Charging:
That's high luxury compared to taking a shower with a rooftop solar
water heater. I got introduced to those in the 1970's in Israel.
Israel has lots of sun, lots of rooftops, and isn't insterested in
wasting power heating what water it pulls out of the Jordan River.
Haifa was literally covered with apartment buildings. The ground
floor was reserved for businesses. The rest were apartments which
were sold, not rented. Every apartment had its solar water heater on
the roof (along with multiple TV antennas at the time) which made
things rather crowded.
Anyway, when you first turn on the water, you get the somewhat warm
water that was sitting in the pipes. About 15 seconds later, you get
scalded by maximumly hot, near boiling, water directly from the solar
water heater. That slowly tapers off in temperature as the rooftop
heater slowly empties. I learned to take a shower with one hand on
the valves.
I've done the same with flash water heaters. They do a somewhat
better job of temperature regulation, but without a ballast tank,
constant adjustment is required. Still, it's more energy efficient
than a tank type water heater. Sacrifices must be made.
