hello, pardon my lack of electrical knowledge ... we had a 2014 S60 that we charged every night in the garage. 40A got us about 29 miles per hour now we have a 2016 P90D that i've checked to make sure is pulling 40A and it's only getting about 25-26 miles per hour. i don't know if the volts have a lot to do with it, because i didn't compare the volts before/after ( although i might have some screen shots from that app in the early days i could go back to). but the app showed 231v last night. in any case, last night i started charging earlier just to watch it get up to speed and it took quite a while to climb up to 25 miles per hour and eventually maxed out at 26. is that normal?
