Sort of. One feature of fuels is that the planes gets lighter as you burn it. You can also choose not to fill it up in order to have more cargo (or passengers)

Batteries don't offer the same flexibility, so they will have to be pretty power dense to provide the same utility. I'm still rooting for electrification there too. I can't imagine an electric drive train to cost as much as a Lycoming/Continental engine overhaul.
