This sucks. You can’t bring a battery through security (as carry-on luggage) unless it’s powering a device. So that eliminates replacement batteries for a device you aren’t carrying with you. And you can’t take a lithium battery as checked luggage in passenger aircraft. Period.
Nor does there appear to be any way (for a consumer)Â to ship stuff here on a genuine cargo plane.
Well. That throws a monkey wrench in my plans.
