As of January 1, 2009, lithium ion batteries over 100Wh are classified as Class 9 Dangerous Goods. RED BRICK batteries are 140Wh and therefore fall into this category.
If you are going to be traveling with your RED BRICKS, you are allowed one larger lithium ion battery installed in a device, plus up to 2 spare larger lithium ion batteries. These are in addition to any smaller lithium ion batteries.
