I still want to try those 140 farad Maxwell Ultra capacitors, it appears as thought they have better ESR than these low-ESR caps. Even factoring in the frequency coefficient for ESR

DC ESR: .0072ohm

1KHz ESR: .0036ohm

It looks like to me they would do a better job with such low esr, and very large capacitance available. Plus you would have extremely high power on tap. Batts would only deliver the average current draw. They are rated for 530 amps with a short circuit, and 15,000 watts/kg. $5 a cap, you would need 8 for 4s LiPo.
