I never removed my battery until a few years ago getting paged while waiting for my flight in Ho Chi Minh City and getting escorted to the bowels of the airport and being asked to remove my bike from the box and remove the battery. Was asked numerous times with the obvious language barrier why was there a battery in the seatpost? All turned out well as it usually does but what a hassle and slightly uncomfortable.
I now always remove my battery.
