Andrew after reading this list and the EVDL, you'll quickly find out you can't 
use automotive or marine starting
batteries. The other bad news is the DOD problem. Most people report that very 
roughly more than 50% DOD ( depth of
discharge) shortens the battery life unacceptably - see the endless pages of 
discussion on DOD on the EVDL archives.

I am interested in building series hybrids with very small clean gensets, if 
you want to talk about that. Its probably
the only way I can go with my long-term project as large-enough lithium packs 
are still out of my budget. I have even
been mulling over electric road-racers with tiny gensets, if anybody wants to 
chew that idea.
