[Elecraft] KX2 batteries on airlines

[Bruce Nourish]

Just checking up on the rules...

The KX2 battery is a ~28 Wh lithium ion. Reading the chart, that means:

* Installed in the KX2, it's legit for carry-on and checked.
* Spares (not installed in the KX2) may be carried on in any quantity,
provided they are for personal use (not resale), and are protected from
short circuit and damage (e.g. tape on the terminals, carried in a
protective pouch).
* Spares may NOT be checked into luggage.

Note that plugging the battery into a charger doesn't make it "installed";
it has to be in the KX2, or it's a spare.
