Yes, this is the exterior charging port for charging the main battery. In the pictures, you can see tape holding the charge port door closed. Without the port, the battery cannot be charged by using the normal connector. I see no reason to believe that installing the charging port would be time-consuming. It's should be a matter of wiring in the port. And yes, the battery would have a charge because there's no way to test the vehicle without a charged battery. It would be absurd to wait until a charge port is added - in the field - before charging the battery and then testing the drive train - in the field.I’m curious about the charging port mentioned. Is everyone talking about the main charger port used to charge the main battery? If that’s missing, what good is the car? Like buying an ICE vehicle without a gas tank. I’m sure installing the charger port is a bit time consuming requiring the shop (instead of at your house). Would the battery even have a charge if there’s no charging port (Pre charged prior to installation?)
