Standards for what batteries you can bring on planes is clear as mud. I recently brought our Scarlet from Vancouver, Canada to Prague, Czech Republic and had no issues bringing 2 160wh GMP batteries in my carry on. I called the Canadian Air Transport Agency beforehand in Vancouver and they weren't clear on the matter themselves... they just pointed to the online info regarding batteries on linked from
www.YVR.com (
http://www.catsa.gc.ca/Page.aspx?id=...=1&mode=list):
"Each spare battery must not exceed: - for lithium metal or lithium alloy batteries, a lithium content of 2 g (i.e.digital/film camera); or - for lithium ion batteries, an aggregate equivalent lithium content of 8 g (cell phone/gaming device/camcorder/laptop). Lithium ion batteries with an aggregate equivalent lithium content of more than 8 g but not more than 25 g (professional A/V equipment) may be carried in carry-on baggage if they are individually protected so as to prevent short circuits and are limited to two spare batteries per person."
There is some weird distinction between batteries for consumer electronics and batteries for personal use. Personal use batteries can be checked. ???
So how much lithium does a GMP 160wh lithium-ion battery have? No clue. There is no info on the battery itself, and no information on the GlobalMediaPro website.
In all honesty, your luck at bringing larger batteries through customs (at least in Canada) depends on how much the border guy thinks he knows about your batteries (this is usually the case in all obscure non-mainstream customs matters). If he's convinced that a 160wh GMP battery has more than 25g of lithium, you're screwed. Personally, I would just assure all border people that the batteries have less than 25g of lithium. What evidence can they find to the contrary? I couldn't.
I just taped the contacts of the batteries (to ensure no chance of shortcircuit... which I believe is how these batteries can explode). The security people didn't care at all about the 2 large batteries I was bringing in my carry-on, even when I had to take everything out of the bag to show the Scarlet brain itself.
