Caps in series act like resistance in parallel, you get something around half the value. Electrolytics paralleled back to front protect each other on AC, btdt, but generally not considered relaible. Btdt also, can you say explosive disassembly?

Not sure if capacitance doubles back to back. Does in parallel but if the electrolytic doesnt properly form, it doesn't produced "rated" capacitance.

Series
When connected in series, the voltage of the supercapacitors increases, but the amp-hour capacity remains the same. This makes them suitable for applications that require high voltage.

Parallel
When connected in parallel, the amp-hour capacity of the supercapacitors increases, but the voltage remains the same.

ie: Very similar to batteries in this respect, so a 4s4p or whatever pack would give similar results as the same in batteries, with the exception that power density (amps) is way higher and energy density is way lower.


I have started looking at DIY supercaps some.
So far they seem legit, cheap and easy and pretty powerful!..?
They can be flat, on car floors, roofs, hoods, door panels, or cylindrical or wrapped around chassis members.

In short:
Anyone buying supercaps might be considered something of an ignoramus with more money than tech sense.

I understand that for capacitors in a series, it's not as simple as that:
