Since my Sparrow looks like it's killing the YT's I have, I'm looking into
possible alternate batteries. Preferably ones with more range! I
currently suck about 5KW out of my pack for my average commute. (This is
really hard on 13 YT's.)
Saft NiCd:
The problem I see here is their physical size. The extra 2.5" height of
the STM 5-100 over YT's is a real killer, as well as not being able to
stuff 156V worth of them into a Sparrow (even ignoring the height
problem.) I dug around on their web page, and found some info on other
sizes of NiCd, but the only one physically short enough is only 15AH (the
SBM 15). By the time you bundle 10 cells of those together to get 12V,
they are larger than an Optima YT - yet have 1/3 (or less) of the
capacity. This seems weird....
Evercell NiZi:
The new Evercell MB80-12-8 looks promising - but their availability is
very questionable.
Li-Ion:
Are any of these kinds of cells available to the hobbyist in the sizes
needed? I know they would be $$$, but I am looking at $/mile, not at up
front costs currently.
If my YT's only work for me for 2000 miles, that is 80c/Mile!
