Word, I run 7s2p pack on a 1512/3D for 38,000rpm and the truck has moe nuts! I then made a 7s pack and geared it for slightly slower, at 40mph it still has lot's of power (~1250 watts), and the truck was little over 9 lbs, it was so nice and agile.
There is a new battery tech i just found today that looks VERY promising. It can discharge 50C continuous and only reach 34*C (93F) in the lab tests. They compared it to an A123 (or at least I think), the A123 cell at 13C (30A) continuous and it reached 66*C (150F).... that has got to tell you something about these cells.
