There's no image link to your question here on ifixit
Are you sure that the 5V - 1A doesn't mean that it the specification required for the power adapter that is connected to the beatsX?
It's not unusual for the adapter voltage specs to be shown on a device near where it is plugged in.
Use this video to open it up and check what it says on the battery itself. Then use that information to search for suppliers.

Hi @jannekehart,
Post some images of both sides of the battery in your question.
Here's how to do this on ifixit Adding images to an existing question
All the batteries I've found for various BeatsX models use a 3.8V Lithium battery so 5V would be very unusual as it isn't a standard value for a Lithium battery, 4.7V is the closest

Hi Jayeff, thank you very much for your answer.
The battery is still inside but it writes it on the outside where the battery is in.
I made a picture but it is very difficult to get it sharp. If you enlarge the image you maybe can see it.
