[Elecraft] Flying with K2

[Ignacy]

I travel with K2 and installed Li-Ion battery. Never a question. There is an
official document by IATA on dangerous goods (search for DGR) and it states
that built in Li-Ion batteries up to a certain power are allowed. EXternal
are fine to 160Wh and  afew limits. Asking is more trouble than help as most
personnel is ignorant of rules and they could create some to appear
competent. 

I would never carry SLA as it is heavy. That Li-Ion batteries are dangerous
is to a point a myth as almost every passenger flies with a laptop. 

You can go to a batterspace.com and search for packs that are NDGR (not
dangerous). This are officially approved for travel. For K3 I would choose
11.1V pack of 3-4AH. Would weigh < half of SLA.  These packs have internal
circuits against overcharging, short circuits, etc.

I think there are no limits on NiMH batteries. batteryspace.com sells many
packs. I don't like them as much as Li-Ion because they are harder to charge
and a single failure means the pack is dead.
