Because supercaps are very lightweight in comparison to additional batteries, the numbers might work out differently than simply adding a battery. But I see the point.
Actually, the reverse is true. Supercapacitors are *bigger* and *heavier* than batteries for a given amount of energy storage... by a huge factor (like 10:1 or worse).
The only merit that capacitors have over batteries is that they can be charged and discharged faster. If you need X watts for minutes or more, batteries are clearly better. But if you need X watts for *seconds*, then supercapacitors are just the thing!
