Yes, I've been thinking that for a while, but it's true that this isn't usually how any brand operates. Personally, I like the idea that if Stark manufactured a battery with the exact same shape but a 10kWh battery we could install it in our first gen EXs, I'd buy it. But reality is different.@Karinshi : you keep asking if Stark would sell newer batteries for older models...
What I do believe will become a reality is an EX model with a 10kWh battery in the future; there's no reason not to. In fact, they'll probably wait until they can reach 10kWh, not 9. It's more impactful. I can already see the headline: "The new Varg EX 1.2 with a 10.8kWh battery, redefining the electric world once again."
And then you can prepare yourself to see thousands of secondmarket Vargs
I really believe this will be or at least must be the reality 3 years from now at max
