@RCW, have your school board contact STL (St Louis ?) city bus depot ! ALL 40(?) of them are DOA,lots of problems the least is not enough electrons to recharge in a timely manner. I'd have to figure out where I saw the info. They need the power to feed a small town JUST to recharge 1/2 the fleet.
battery busses should be great on hills, lots of bottom end torque, if the computer was programmed right
BTW keep eye open for when the old diesel busses get sold off ! Might be real cheap and you can sell them back in 2 -3 years, or rent them out when the batteried busses go DOA !!!
