Ok let me chime in one more thought.... I assume the battery "process" is the same across the line.
If you get a 160 mile pack, that would equate to roughly 125 miles on a standard charge as range charges are not recommended. So as long as your anxiety level is low, you'll be fine. But, if you're needing to make any one way trip around 50 miles, you're gonna get anxious. Especially if you are using a lot of juice (70 mph, a/c, lights at night).
Just my .02 cents.
