ZPB: OK, but 140F will make one hell of an arc! Current would be theoretically infinite, only limited by the battery capacity and wire gauge. IIRC, last time this came up, I suggested that you permanently wire a cap to each pack to avoid arcing from the initial connection. Just use a resistor on initial charge to force a lower charge. This would definitely let you use much lower C-rate batteries since the cap will take care of just about all current pulses. And you'll get closer to the actual Ah of a battery since it won't be running as hard. However, will the price and weight increase be worth it? I say you try it and see - I'd MUCH rather spend your money ;)

Are you sure those are the ones that Quark uses? If so, I'll probably wire an extra two on the Quark and a couple on the MM.

suicideneil: Running a capacitor at lower voltage is perfectly fine, it will actually extend the life of the internal insulator since it's not running close to its max. The only downside is the slightly bigger physical size. It'll be better for your batteries, but not sure if you'll see a noticeable increase in performance. But it sure won't hurt - just make sure you hook it up right. :)
