hello there.. i tried looking for answers to these questions and can't seem to find them, so i apologies if these have been asked already! just received my refreshed model s 70d. was curious where i can find out if my car has 48v or 72v charger? i know it's currently standard as 72 and needs to be "unlocked" to get to it, but my delivery specialist said something about mine being equipped with 72, but i can't seem to find out where to find that info in my car? any clue? i'm assuming he was just letting me know that mine was indeed delivered with that option, if i wanted to pay to unlock it. secondly, does having 72 "unlocked" allow superchargers to charge my car faster too, or just overnight home charging? lastly, my delivery specialist recommended that i charge it to the highest point in my "daily" usage (90%).. i'm curious: since it's shipped with a 75k battery that i have not "unlocked", does that mean i have less reason for concern to have it charge to 90% daily of 70k? not sure if this question makes sense, but hopefully it does! want to make sure i'm treating this beautiful new car right, as it's my first electric! thanks!!
