To be clear, Metro intends to support 100% of its routes with EVs. The
"70%" refers to how many routes can be served by a bus with 140 miles
range. (Most routes are relatively short, I'll *guess* 10 miles urban,
20 miles suburban.)
Here's a publication on test results, from 2017. (I haven't spent the
time to read it.)

Very interesting, and fairly consistent with my post. They have about 70% of
routes that they think are applicable, though they base that solely on a 140
mile range, rather than their testing results.
It was odd that they didn’t have much info on their testing, and they still
hadn’t completed their cold weather testing.
I think that DOE collects and analyzes data from all the places that test
and/or zero emission technologies.

Here's some background info for you, Susan. Seattle (actually Metro of King
County) is in the process of converting to 100% electric by 2040. They have
been testing EV buses for a few years and plan the first roll-out in 2021. You
can get an overview here:
https://kingcounty.gov/depts/transportation/metro/programs-projects/innovation-technology/zero-emission-fleet.aspx
And here is a detailed report with lots of data that might be useful to you:

I'm pretty sure Metro has been testing on hills. Our area is full of steep
hills, narrow lanes, sharp corners, all kinds of route challenges. Plus our
climate is chilly for a good part of the year, though nothing like what the
northern plains and east coast gets. But certainly colder than Florida :) If it
can work for Seattle, I can't imagine an argument against in Florida !
If it would help to speak to someone in the program, I might be able to find a
contact. Not sure, though.

This is a question that can’t be answered on the basis of the information
given, and will likely vary by agency.
It suitability depends on a number of factors. Climate is one. The route is a
major factor, and whether or not the bus agency is able to or is willing to
change routes. The grades and length of the route is an important factor. I’ve
heard of some agencies that could run 80+ % of their existing routes on
batteries only, others less and others more.
Have a short route on a flat grade? Maybe it is suitable. Or, as happened in
California, try to put a battery electric bus in service in the mountains in
winter - a miserable failure (this was for some school buses).
