Why not? They're shipped with airplanes from the US to Europe etc.

As long as you won't keep the battery in your pocket together with your keys just like I did with a nicd cell you won't get hurt

Yes, but the planes they ship on are pressurized to at least 5000 ft. If you are flying in your own private job above that then I might look into that. After all they are just bags of polymerized metals.

This will be a regular commercial airliner with the Batts in the under carriage baggage.

It will be fine, many people transported electrics to Vegas a few weeks ago and there was no problems.

Personally, I would not carry or allow anyone to carry them on my plane. Remember the oxygen cannister in Value Jet? I know that they are in computers and phones...there they are not easily damaged. Loose cells can be ruptured...turning them into flares!

Just my procedure...

I would declare them at check-in. They are going to seriously impress the x-ray systems and your luggage will likely be opened and hand inspected. It might be helpful to include a note with the batteries stating exactly what they are.

However if your batteries are valued at $500ea and combined with the potential possibility that security personel are going to confiscate them, you might try mailing them to the destination. Mail them to general delivery at a post office near your destination. The post office will hold your package for 30 days or so while waiting for you to pick it up.

Here are some links I found:
They refer to non-rechargable lithium batteries.

Mark...
Got this one from the third link in the first paragraph.

If you fly your heli on the airplane, does that make the airplane lighter?

"put together a Temp Foamie while im out there."
Oh so we are talking about 2000mah or less. Just put them in any uncrushable box and forget it. You just want to make sure that they don't short or sustain any physical damage.

"LiPos in a small pyrex dish with a sandbag over them"
Uhh.. that's pretty much a textbook explosive tamping system. Don't do that. You may actually get arrested for creating a simulated bomb. (Yes, I'm a little paranoid of the resulting effects of the PATRIOT act.)

When preparing a good explosion, you need to hold the explosive medium in a confined space so that it builds up a great deal of pressure before being allowed to expand. Some C4, wrapped in a sandbag, in a pyrex dish would be just the ticket. If I were watching the x-ray, this is what I would be looking for. Don't make it look like that.

I'd just protect them by putting them in a thick sock, or a box.

Reading my previous post, I may have overstated the risk of creating something that looks suspicious. But I read stories about weird injustices all the time. So I guess it's worth it to try to think ahead about these things.
