They don't need to be removed.
Per their FAQ
Is the battery allowed on planes?
Your suitcase battery is compliant with FAA, TSA, and DOT regulations and meets UN/DOT 38.3 requirements. It can be checked or carried onto any flight other than flights originating in Asia, where it can only be carried on. You can find more details here.
If you need to take out the battery for any reason, we’ve included a screwdriver for quick removal. When flying out of Asia, remove the battery before going through security (they’re sticklers there).
