Pinebook Pro?

[PakoSt]

I still have 3 questions about the Pinebook Pro:
1 - I read that it is an 10Ah battery, but what is the voltage? Ah doesn't say much, unless the voltage is provided as well. I gues it is a single cell, so 37Wh? If this is the case, I guess it would be possible as well to connect more cells in parallel ourselves, if one is okay with the extra weight and wants longer battery life? Any chance you can provide us with pictures of the inside of the Pro?
2 - Excited about the NVMe storage option! However, does this NVMe port support SATA as well? (I currently don't have an NVMe SSD, but I do have an M.2 SATA one)
3 - Would the WiFi/Bluetooth chip be interchangable with a WiFi/Bluetooth/4G chip? This is not that interesting to me, since I have a very light data plan, but I think a lot of us would be very interested if this would be possible by swapping out the chip. I thought in the Pinebook this was a seperate Realtek chip, so any chance this might be possible?

Excited about this project!

You can check the FOSDEM 2019 post. At the bottom you can see the internals of the Pinebook Pro:

1 - From the image, you can see that it's 4.5V in the prototype unit. Not sure if there was confirmation that this is finalized.
2 - Not sure about SATA SSD. From the given info, there will be an adapter for the PCIe NVMe M.2 drive which will be used for the connector on bottom right of the main board on the image. From what I remember PCIe NVMe M.2 uses only M key so physically it should be possible to plug a SATA one (which uses both M and B key). Someone with more knowledge can say if it would actually function.
