It seems like the most practical way to approach this as an airline passenger is to place your battery into superposition where the battery can be both within arm’s reach, but also stowed away. Warning, do not observer or interact with the battery while the flight is in the air lest you collapse the waveform and lose superposition.
Tldr:
Check with your airline before traveling.

That seems overly complicated. How about just bringing an extra arm in the carry-on?
If you just bring s whole other person in your checked bags, you save on ticket costs, too.
