New battery recharges in one minute

* charges 80% in one minute, tops off in just a few minutes.
* loses only 1% of capacity after 1,000 charge/discharge cycles

If it was safe to use it on an HT, and the recharging cost wasn't horrendous, it could be very very cool.

But man, it would take a lot of power to charge an HT-sized set of batteries that quickly.
