I just picked up a second hand PV102 10000 lumen video light by scubalamp. It has a contained 7X18650 battery pack. I am trying to find if this is allowed on airline travel. I know lithium packs need to be carried in carryon luggage, but I am having a hard time finding if this battery pack meets all the TSA regulations. Does anyone have this or large sized batteries like this who can point me the right way?
