Re: Highest energy cap that's available in hobby volumes .. maybe a few hundred pieces

like film caps, they just start leaking more.

That is only true if the useage currents and period allow the leakage
to self balance the, in this case I do plan to use them in my Corvair
EV conversion project, where the charge/discharge currents will be
paralled with the batteries, and modestly high.

For use in EV projects, the Maxwell caps MUST have an active balancing
network, as just the variance in capacitance will take the caps over
voltage if you attempt to use most of their capacity.
