Taking a Spark on a plane - how many batteries allowed?

Hello mate
You need to check with the airline but I took 3 M2P batteries to Portugal recently and had no issues.In retrospect, don’t think I needed to bother with draining the batteries either

Draining batteries for a flight to Portugal

Hi all Does anyone know if you have to actually drain mavic 2 pro batteries before boarding an aeroplane? Same question for taping up the electrical terminals?
