Yah, so preferably getting the smallest pack possible to take care of the spikes and bursts. Enough to keep the voltage up at nominal.

However, even a small voltage 'difference' from nominal voltage would equate to large currents, again, like you said, a cap of this size is basically a short circuit...

So you say 1/10 th of a second eh? :) That sounds good then...

Do you think 2300 Joules is enough, that is a 8s 140 farad (17.5 F.) cap bank. @ 232 grams with 500 amp

Or the larger one at 480 grams, 8s 310 farad (38.75 F.) cap bank with 5300 Joules with 1500 amp
