This is a most excellent place for technology news and articles.
Idk about renting, sounds like ass.
A core charge would make more sense, like swapping propane tanks you get a discount for having the empty core with you.
Wpuld you rather purchase an 80 kWh battery, alrhough you need most of the time only 20 kWh or purchase only 20 kWh and rent/swap some batteries when needed?
I'm no talking about renting all battery capacity the whole year, just the extra capacity for the 2-4 weeks in the year when long-distance rides are in the mix.
