  First never believe anything  Pike says as they are mostly wrong. Not sure who is paying them off or if they are just incompendent.  Likely getting paid to give a customers viewpoint/bias.

  Next as an EV designer, builder and driver one should never design a larger battery pack without cooling.  Cars get 60C just sitting in the summer sun turned off.  Just ask anyone in the south.

   EV's shouldn't have more than 100-150 mile range as after that a ICE generator is far more cost effective and gives unlimited range.  All my EV's have or will have a 40lb generator giving unlimitede range. 80 mile range is probably the sweet spot.

A123's have so little resistance they put out huge amounts if specific power with little heat generation.  I agree this is just a small improvement mostly gained by higher battery weight/kwhr.  This means more material though as they said, Iron, alum, Lithium, plastic, etc is cheap with most under $4/lb and averaging about $6/lb.  Most Lithium batts are about 22 lbs so it's just not that costly.

I buy complete A123 battery pack systems/BMS, etc for about $700/kwhr custom made from cylinder cells that can and has done 170mph and 7.9sec 1/4 mile though that was recently broken to 200mph and 6.9sec EV  IIRC.

Beth, you are right there.  Time is an issue.  It takes time to prove a technology does in practice what it does in the lab.  I think they have something here, and it is a good trend.  Let's see if investors think so too.

On paper, or maybe even in limited testing, it seems like A123 has made a big leap with its lithium-ion cells in terms of reducing cooling requirements. Nevertheless, there is still a lot of skepticism that the company will have to over come. Commercializing these efforts will take a lot of time and money, which is something A123 and its battery maker competitors don't necessarily have.
