Well now you've just made me an engineering scenario of aircraft equiped with drop tanks full of heavy batteries used to extend range. Drop tanks that they let go mid flight 'bombs away!' as they discharge.

So all we need then is parachutes, some kind of GPS based glide guidance control, and a network of aviation battery collection stations :)
I guess overseas flights will just have to absorb the cost, unless it happens to be economical somehow to operate floating stations for the purpose of collecting dropped batteries.

Rocket Lab's Electron rocket actually does this with the batteries that power its electric turbo pumps.
> The electric pumps are powered by lithium-polymer batteries. The second stage uses three batteries which are "hot swapped", two of the batteries are jettisoned once depleted to shed mass.
