Ok, that makes a "little" more sense. I was assuming that the buffer batteries don't do much except reduce ripple. Still to have batteries that can provide enough amps to support what the warp9 is capable of, you need 12 of them that can deliver 600ish amps, plus figuring out how to charge them without overcharging them from the generator but without undercharging them also. And the generator output needs to be efficiently regulated to ~162 volts. But battery recharge needs to be managed after the batteries are drained so that there is sufficient power for motoring.
The price on large generators does not seem to drop in proportion to power at these levels though, but at least it doesn't look so much like you have a locomotive engine in the bed
And the deeper discharge runs are going to affect automotive battery life.
