That’ll depend completely on the airline. Must likely you’ll need to bring it on as carry on, pretty sure you won’t find an airline who allows a lithium battery in cargo. Since it’s a huge piece of gear, it won’t fit in any carry on luggage, so you’d have to check it in as special carry on. For any travels at high altitudes it’s important to have less than 60% battery percentage to not get damage to it. So many people complain about their computers battery not lasting long, but most times it’s because they flew with fully charged battery or charged it to 100% during flight, and batteries chemistry doesn’t work the same at 35,000 ft in the air as on the ground.

Short answer, you need to ask your specific airline before traveling.
