I flew from tampa to dallas and then japan to cebu. I have the go pro case with that being said I had no issues with the batteries as i was in compliance with regulations as a carry on. Reminder that T47 are unlimited to carry and the T48 are limited to 3(1 being in your aircraft for tranport) other two have to be carried as carry on. Hope this helps
they recommend to tape up the connectors as a safety....as carry on..
