Traveling overseas with Foildrive battery pack

Does anyone have experience traveling overseas with Foildrive travel batteries. I reached out to Qantas and they provided me a form covering me for a year to travel with jetstar and Qantas.
I’m particularly interested in owners experience in south east Asia, Vietjet said I couldn’t and air Asia said ask the airline.

check out this topic at FoilDrive Owners Facebook group. It’s well covered
