The cap. back would weight in at 480 grams and has a peak voltage of 20 volts at 38.75 farads, which equals to 5275 Joules of energy. This 'type' of power in combination with the battery discharge capability, the output power of this hybrid pack would be phenomenal. It would also get rid of erratic voltage fluctuations...
The voltage under hard acceleration would stay almost at nominal state (16.5v) and would have very, VERY flat discharge curve (that is bursting power). You would have to use 8 cells in series for 20 volts peak (2.5 volts/cell), capacity goes down by C/Sc
The specs for the cap is:
Capacity: 310 farads
Voltage: 2.5 volts
Current: 1500 amps
Length: 62mm
Diameter: 33mm
There is also smaller cells,
120 farads
140 farads
and a 350 farads capacitors

I am in the process of testing 58F version... :)
