Maxwell Ultra-Cap's/Lithium cells hybrid pack

Yeah, if you are set up for that kind of thing and understand the possible risks if not done right, it should work great. Doesn't seem to be something that will be available for the masses anytime soon though.

The bursts doen't last very long; basically however long it takes for the motor to reach the rpm of the signal it's being fed, which is mostly on take-off out of the hole, and any hard acceleration. I'm sure there are a couple graphs of an EagleTree plot around here somewhere.

150uA delf discharge; not bad. According to my calculations, it would take about 3.5 years to totally drain a 4.6Ah pack not including the self-discharge of the battery itself.
