Generic accessories almost always work across drones, things like bags and landing pads are straight-forward enough. The DJI FPV battery uses a new charger connector, but the Goggles and remotes all charge via USB Type-C. Officially, no older remotes work with the FPV, and the newer remotes do not work with the older drones. Propellers absolutely will not work across drones here either. The FPV Goggles V2 will work with a few other DJI products.
