> Don't you gain some battery life (and thus range) by having a gearbox? Automatic or manual. Yes, but that's traded for more weight (thus less range), as well as increased complexity and maintenance. And at "normal" speeds, you gain very little efficiency, the second gear is for cruising on unlimited autobahn segments. At which point you're getting hosed by aerodynamics anyway. If it was so valuable every EV manufacturer would use them, but that's not the case, if anything they're getting scaled back (e.g. the original Formula E had 5-speeds).
