It is ridiculous to use MPG (Miles Per Gallon) to measure efficiency when referring to battery power. Also, we should start using metric system (MPL) like the rest of the world.
Batteries, especially LiFePO4, are not liquid, but both battery and gasoline produce energy. For each, how much energy produced can be converted to work? That determines efficiency.
