LOL I actually have a 3.5F capacitor for automotive electronics on my test robot frame at home. It basically comes with it's own welder.

I was thinking something more like this:

I love that datasheet.
For tolerance it lists: -20%〜+80%
So I guess it's perfectly okay to send out a 15F capacitor instead of a 10F capacitor?
Might make the RC time constants *just a bit* longer.

BTW: With a capacitance this large one really needs to consider the currents that will flow if that capacitance is entirely discharged and someone connects a power source to it. Luckily with control system boot and robot setup times of at least 1 minute there's time to charge it slowly. Though I still doubt it is legal in FRC.
