Need some more detailed information about the battery

Hello,

I'm in need of some more detailed information about the built in battery. The main info I could find was 40Wh or 5.313 mAh not much more.

What I need to know is, how many cells the battery gas. If it's for example 2x20Wh or a different configuration.

I wasn't able to find any information or data sheet about it.

Kind regards,

Thoscho
