Controller in the suitcase?

Day everybody,

I come directly to my question. I'm flying to France for days, wondering where to put PS4 controllers. That's what I think lithium batteries, so they would belong in the hand luggage, right?

I would rather keep them in the suitcase, because I'm unlikely to use these controllers while I travel.

You can take out the battery pack and put it in your hand luggage.

The batteries must be in your hand luggage. The controller can be in the suitcase…
