Hi all. I had a p85d for awhile, but needed that extra 15 for a trip i take. It saves me ~30 mins or more (travel with 4 kids) and only 1 stop instead of 2. I was hoping i could upgrade my p85d (had 80 amp charger) to the 100 battery pack but that will not happen. So i bought a p100d. Unfortunately its only has the 48 amp charger. I thought we could upgrade it to the 72 amp charger, but I was told only the original owner can do that. This is a CPO vehicle. They are telling me I'm stuck. Is there anyone I can talk to. I use the car a lot and want the high charger to do quick charges. I do not charge just at home overnight. any advice?
