Are you saying the FCC writes one thing in the regulation, but will enforce something different?

The language I see there now is unambiguous, "batteries". Lithium-ion battery for my impact driver can be used to fly an FPV drone. It does not have an FCC certification because it does not emit any RF, and the FCC never required it to be certified before. Now looks like it can no longer be imported, at least not until either Department of War or Department of Homeland Security deems it not a threat.
