The only batteries I have in a checked bag are coin type batteries. And maybe AA or AAA NiMH batteries for my taillight flasher or camping headlamp. I do not have electronic shifting, so I am clueless on that topic.
Any form of compressed gasses have never been allowed on planes, that includes the CO2 cartridges. Get a good pump. Road Morph G or Lezyne Micro Floor Drive are my favorites.
