We are going to Sorong in October (land in Jakarta, then to Sorong, return Ambon to Jakarta then to Tokyo) and started worrying about all my batteries, to have them confiscated would really suck. I will have many batteries with me, camera, strobe, video lights, laser pointer, about 20 in total. They are all rechargeable, carry on or checked? I will have weight problems but will worry about that later. Tanks! Bill
