Wow, there are some really good developments in Li-Ion recently....145Wh/kg?!?!
$7000 per pack is not bad at all, let alone $4000. I had calculated that for about the same range, or less, I'd need $32,000 of Thunder-Sky batteries (with no quantity-price-reduction). I am probably off somewhere, but still, these new Li-Ion technologies look like they'll end up in my next/current EV. NiMH doesn't seem to be quite as good as originally planned, at least compared to the cost. Maybe we all could order some together and get a discount? Some federal/state/university funding wouldn't hurt either. I think the best choice for me now would be (100) 50Ah 3.6V units. It should give about 60-70 miles of range, and I wouldn't need any power supplies to step up the low PbA-configuration voltage I have now (96->360), to drive my 15HP AC motor.
