I've been building a rear, lower, "luggage" carrier for my Sparrow.
This is to carry a small generator as a range extender. (Kipor KGE 3000).
One thing I realized was that I might be able to get the same range
extending with a lightweight battery pack. Since this is in addition to
the normal Sparrow Optimas, I don't have to worry about fitting the
odd-sized battery boxes. I'll have something like an 18" cube of space
to work with.
I don't need Power for acceleration, 2KW continuous draw should be ok.
Pretty much any voltage is ok, as I'd be using my PFC40 as the DC-DC to
transfer the power to the Optima pack.
So, is there any battery that could store at least 2 kwh, fit in about
3+ cu ft, and put out 2 kw of power?
And how ridiculously expensive would it be?
