What kind of performance would the Tesla have

[Lauri]

lutach - higher C-values make batteries A LOT HEAVIER also! This is not 5 or 10% but can be up to 30% or even 50%! This is from RC. I have places where 1C LiPos would be ideal. Sadly it is hard to get those low-C batteries. And on my 1/8th buggy I want to have 30-40C battery. Don't have the figures with me at the moment but the difference is big.

If Tesla's or any other electric car's battery weighs X with slow-charge battery that gives out enough energy. Then the weight would be 1.5x with fast-charge battery that gives out a lot energy (high-C). Because we don't have the infrastructure for fast charging "sockets" I'd go with the first just like Tesla has.
