Yeah it's not in there yet, but I'll get it there before too long.   
Gary Ellis and I are still working on some finishing bits, such as  
improved cooling for the Kelly controller.  It also needs some other  
small things and some cosmetic work done, and I don't feel it's quite  
ready for showing yet.  I'll be going to Fredericksburg for Saturday  
only, and don't plan to take the car this time.

Regarding batteries, I'd also say that if I do another conversion,  
I'll be highly inclined to go with Lithium Iron Phosphate, unless  
something even better comes along.  I think the performance and  
lifespan tradeoffs are leaning in favor of LiFePO4 now, even at the  
much higher cost.  The main downside aside from the cost seems to be  
the complexity of proper battery management to insure the lifespan.
