Just imagine what kind of motor/compressor you could power with 48 volts?

I think the key piece of information is that these batteries have lower internal resistance. That lets them dump harder, faster, and recover quicker.

I follow your logic on this, but isn't there a point at which the controller or motor can no longer make use of the available current? To increase the current, either you have lower internal resistance batts, or double up on the batteries(parallel), either should provide the added current. Just going from memory, the 1.5 provided an extra ~.5psi at 7000rpm. I started with dual dumps and was logging comparable boost numbers to the 1.5. Then Rob came out with the 2.0 setup which was just a battery substitution that was supposed to produce the same performance as the 1.5, only less complicated and in a smaller package with maybe a bit less capacity. If I understand you correctly, you are saying that either the SHURiKEN produces higher current than the 2.0 (which the controller can make use of), or the 2.0 is inferior to the 1.5, or even my dual 1.0 setup doesn't produce enough current to fully "saturate" the controller/motor, or finally that I may be misunderstanding the nature of the controller and/or motor.
