Why usable capacity is a better planning number than advertised battery size.
Advertised battery size is not the same thing as energy you should plan on using. Depending on chemistry and system design, the useful planning number can be much lower.
Once you bring efficiency and battery health into the picture, runtime estimates become less exciting but much more useful. That shift alone prevents a lot of trip friction.
Usable capacity is where marketing ends and practical planning starts.
