I got my four A123 20Ah pouch cells this weekend. I will be doing some testing and have already taken some pictures and shared some info. I am posting all my info here:

I'll be going over how I am going to assemble the pouch cells, showing charge/discharge curves at .5C, 1C, and 2C rates, and then probably put the battery into my Paseo for use as a starting battery. That is the current plan unless anyone else has any cool/fun ideas.
