serious professional UAS pilots who fly with large collections of batteries specifically choose battery packs that are approximately 99Wh per pack, which fits within common IATA requirements for carry on luggage. on really big UAS such as for cinematic filming purposes these will commonly be connected in series for a 12S string. An interesting loophole which is applied differently, by different airlines, is that you can have multiples of 99 watt hour battery packs individually carried into the cabin, as long as they are discrete units. another interesting note is that a number of $2000-3000 (USD) gaming laptops are also equipped with 99Wh nominally rated battery packs so that they're still legal to take on an airplane. I was recently shopping for a new gaming laptop and ran into this while evaluating the specs of 11th/12th gen Intel series things from the usual Taiwanese vendors (asus, msi) and their ryzen 5xxx based offerings.
