Please see
http://www.iata.org/whatwedo/cargo/dgr/ ... rFlyer.jpg for current airline restrictions that allow both VML™ and VLX™ portable battery power sources to travel globally.
The VLX™ LiFePO4 battery has been re-certified to meet IATA standards for global passenger travel worldwide. Note that IATA regulations now allow complete VLM™/VLX™ packages, with batteries installed, to be placed in checked baggage, and up to 2 spare batteries per passenger must be carry on luggage.
There is an IATA notation indicating "Operator Approval" which means certain airlines to certain countries may still impose their own restrictions on Lithium Batteries. We suggest you call your airline ahead of travel to make sure they don't have special restrictions beyond the IATA regulations.

Also note that several hundred VLX™ fast recycle/long battery life power supplies have been delivered, but we have yet to see any actual-use reviews or complaints except that some don't like the VLX™ colors. Come on guys and girls, tell us you experiences here.
VLX™ should be a must-have for power shooters.
