Going 6s for the bulk of the packs will require 16 packs to get to 96p, and another 3s pack to make it up to 99s. Less connections that way... If 17packs in series could be considered less... Imagine the balancer?
I went with zippy flightmax 25c 5000mah cells
528 6s packs, $34320 and 866lbs
33 3s packs, $1221 and 27lbs
So 561 packs, 893lbs and $35,541
But that would be one helluva pack!
4125amps cont.... HAHAHAHAHA
25c at 5ah = 125amps times 33p....
I am guessing 10c cells would be plenty, and cheaper. Maybe lighter as well.

With the kind of money Tesla got, they could use some of the cells I'm planning on using for my race car. I think going 99S5P of a 14Ah 640g each (70Ah at 3.2Kg) that is capable of up to 250C would be enough. The cell holds 3V+ at 1000A using an 80% DOD. So at 5 of them in parallel, that's a nice 5000A, but if the Tesla under hard acceleration can pull 800A+, the voltage will be much higher. There are even more powerful cells that only weighs 1Kg.
