General Advice:
Under 100Wh Lithium Battery Regulations
Allowed in Carry On Baggage in Equipment or as Spares
Allowed on your person
No Airline Approval Needed
Not allowed in Hold Luggage
100Wh – 160Wh Lithium Battery Regulations
Allowed in Carry On Baggage in Equipment or as Spares
Allowed on your person Airline Approval Needed
Not allowed in Hold Luggage
Over 160Wh = Forbidden!!!
