This is the first time I’m taking a bike with me on a flight, and I’d like to know what the correct procedure is.
United Airline says no loose lithium battery may be in checked baggage. Does the loose lithium battery rule apply to either my Di2 battery (3.7 Wh, housed in a Shimano-made external housing) or my power meter (2 x 2.7 Wh, whose battery is fully enclosed).
I previously checked with a power meter, though that one used a coin battery.
I usually pop the coin cell battery out of a power meter just so it’s not constantly waking up from vibrations while in transport. No other battery-related issues traveling by air, personally.
