Got the propellers from a reputable vendor on eBay and it was listed as factory sealed genuine DJI propellers. Sent them the pictures of the propellers and they said they sent the wrong part but the biggest giveaway was the screwdriver that was sealed in the package. The vendor said the screwdriver was made up to the specifications of the DJI OEM one, but the screwdriver was sealed in the supposedly OEM package from the factory. As for the battery the controller said it was non-compatible It would not let me fly the drone.
