Battery density is only half the issue. The other one is efficiency. Half-century-old cessnas fly like a brick. State of the art aerodynamic performance can allow you to get two or three times the range you'd get just swapping out their engine for battery+electric.
This aircraft can probably do about 400km range. With reserves, maybe 350km. That's not nothing, about Bakersfield to San Jose. And this thing is not fully optimized. If you REALLY wanted distance, you'd pressurize the cabin, use even higher aspect ratio wings, retractable gear, blend the body into the wing a bit, etc, and you could do up to about 1000km range with today's batteries (you'd be mostly battery by weight).
