It is better to use Wh. Assume about 200 Wh per mile.

But as some are stating here I could go 70 miles with a 120AH pack? Lithium is not some miracle battery, yes lighter weight, so there would be a distance gain there, but not 10 miles or more. Math is math and a battery rated at 100 ah is a battery rated at 100ah. Reminds me as a kid when you tried to trick someone and ask them what weighed more, a ton of bricks or a ton of feathers.
