Man, I made changes to the post for Tesla's blog, but they still didn't didn't post it. What is wrong with them? I didn't say anything that violated their rules, did I? Can any of you copy and post it to see if they allow it? Here is the link:

Here it is again:
If Tesla uses higher rate of discharge batteries, they wouldn't need a pack that weighs 1000 pounds and you can get better performance out of it. Is it a price issue as why to use the lower C rated Energy type cells? I have access to similar capacity cells that has the capability of 60-100C rate of discharge and 10 second burst of up to 200C above 2 volts (Not A123 Systems). The Panasonic cells might not even be able to pull 10 or 20C rate of discharge. The datasheet only shows info of 2C rate of discharge, so the Tesla pack would realistic be only capable of 300A. Now lets give it the benefit of the doubt it puts out 5-8C rate of discharge at above 2 volts and that's around the 800A+ they claimed it made in a video I saw. Tesla (Elon Musk), try using better cells instead of Laptop cells and see how faster your Tesla will be (0-60), because it'll be able to hold its voltage higher while putting out more power. You can even get faster charging times as well due to the cells being able to accept a higher current. All you have to do if offer a more powerful charger for the clients who needs it.
