It has turned chilly here in Portland, with nighttime temps in the 40's, and that turns out to mean that my batteries don't charge as well as they used to. My range is down to 30 miles now. I did go 30miles the other day with some 55 mph stretches and two adults and 150 pounds of equipment for work. When I got back I was pretty sluggish accelerating from stop lights and my battery back read 148V. (144V should be the lowest I could go)
To get back to normal battery behavior I am going to need to heat the batteries with some sort of electric blanket or wiring, or wait till spring. From asking questions on the EVDL.org forum, I need to keep the pack near 70 degrees, and my rear pack isn't well insulated.

What's the bus weight with the new engine and all the batteries ?
I don't really know th eexact weight, but I'm guessing 700 pounds heavier than when the bus was original. Someday I'll get it weighed.
Just wanted to say I really enjoyed reading this blog and look forward to the day when I have the money to convert my 78 bus. I just watched "Who Killed the Electric Car?" and now I want one!
