[ausev] Trike conversion: Circuit Question.

[Carey King]

I also like the idea of figuring how to include the ultracapacitors. In 
addition to possible boost power, they can also get recharged quickly. 
The rate of discharge should also be better from them. Don't know if you 
can store enough energy in them for what you need, but by knowing the 
mass of the trike, and the speed you'd like to go from and get to 
(1/2*m*(V2^2-V1^2)), that's a good start. Also the recharging of them 
could be very simple and separate from the batteries. I don't know if 
this is much simpler or worse, but an interesting idea.
