40 ah vs the porsche's 18, and only 13 pounds (6kg for you beedub)

I have no idea if they will fit however, do not quote me on saying they will. What are the dimensions of our battery box?

EDIT: here's one that's already in series: http://www.electricmotorsport.com/st...f_gbs_40ah.php

Probably more pita than it sounds. This one's 11lbs for $160
