I just found out that Transport Canada does not allow LiPO batteries with a rating of more than 160 Wh to be taken on a plane. They also can't contain more than 2 grams of lithium. So the standard Phantom battery is rated at 2200 mAh (2.2 Ah), and produces a 11.1 volt current, which means that it has 2.2 Ah x 11.1 v = 24.4 Wh (correct me if I'm wrong). This means I should be able to take it on an airplane- but only as carry on baggage. Note that unless the battery is in a device, it can't be taken as checked baggage. But the Phantom battery does not state how much lithium it contains- so does anyone know if it meets the 2 gram rule? Has anyone had much experience carrying the Phantom and spare batteries on airplanes and, if so, have you ever experienced any hassles?
