In case anyone is wondering, here are specs on some of the 3200mah Flightpower packs. Pretty impressive IMO.

Using 2S2P, a couple of these packs should make for a great 4S setup that will fit the E maxx and E Revo trucks.
2P yields some good discharge numbers: 192 amps continous, 384 amps Burst or 30C - 50C.
Please reserve for me a couple of the 2S2P packs.
