Hopefully, because if they were wired in series that's a nasty failure waiting to happen as they'll get imbalanced and then one will go overvoltage and let the magic smoke out.

Also, it's generally not a good idea to connect supercaps directly to a power source with no current limiting because their internal resistance is low enough that they behave like a short when first connected.

There are many ways to solve this problem that are easily found via googling. EEVblog etc.
