We now have many cars that have a large amount of these batteries driving around every day charging and discharging more than probably happens on these aircraft. Fix the over heating problem and its no big deal. Put it in a fire proof box and we're all the better.
AERO - 787 No-Bleed Systems

Pretty interesting decision making process that they went through for 3% burn. As I see it, there are no bleeds on the 787. All electrical. Have no idea how it works, but that is right off of Boeing's website. Must hit the batteries pretty hard to require the switch from more traditional battery technology where all the batts have to do is start the APU and be ready for a backup role should everything else (including the RAT) fail.

As an aside, I have a small business in the radio control hobby world, and use both Li-Ion and Li-Po batteries extensively. We treat them like a ticking time bomb. Stored, transported and charged in a firesafe. I also charge them on a concrete floor away from any combustibles. I know of at least a dozen garage/house fires as a result of this technology being abused. I also have some experience with faulty cells and Lithium fires. Very hot fire and no way to put it out. Not a good thing on an airplane.
