This is one of those annoying cases where the OP has vanished after
the initial post and is not answering questions. Without more info,
it's a wasted effort.

Something along the lines of Field's relay method post... maybe with
MOSFET's... is most likely to succeed... just needs the right
controls

Jim... I haven't vanished, just out of town. I don't quite understand
what clairification you require... 10 caps in series to give 27VDC total
operating voltage.. each with "something" in parallel to prevent over
voltage... overvoltage will cause "super capacitors" to short and fail..
that "something" must be such that it will not discharge the capacitors
when the 25 volts is removed, turned off, disconnected, not charging,
etc.

Bill

Do you know how much voltage is safe for those caps? Do you have a
voltage:current curve?

Do you have a clue? Not likely :-}

...Jim Thompson

You're repeating yourself, without content, as usual.

And if you want to design an elaborate protection circuit for an
expensive part that you don't understand, do that again, too.
