Theoretically 75kW, actually. 20-30C. Of course, if I actually took it to 30C there would be a large voltage drop (so wouldn't actually be 75kW) and it would severely shorten the cycle life....and it would completely drain it in 2 minutes...if it didn't burst into flames first..
But yeah, it is kinda crazy to think about the potential. You want crazy though? Once it's complete, the whole pack would theoretically be capable of a burst discharge of up to almost 375kW!
For craziness with lipo though, check out this build. 20kWh of this lipo in a Mazda MX-5 with a 300kW controller/motor combo!

For context for the petrol-heads in the audience, 1HP == 746W, so 300kW ~= 400HP. ...in a 2,000lb car....with 400+ ft-lb of torque from 0RPM...
