Pinebook Pro?

[brent.thierens]

1 - There is no such thing as a standard battery
2 - warranty nightmare and one of the reasons we don't sell DIY kits
3 - There are no resellers in parts of the world (e.g. EU)
4 - How does that make it easier? the legal requirement for high-risk goods shipping states 'lithium ion batteries or devices containing lithium ion batteries(...)' ; so shipping a battery from China wouldn't be simple or cheap either.

Yeah I know batteries comes in all sort of power and shape. I'd be thinking about an encased, rectangular shaped and sized that could be live fitted into a slot like a pcmcia card. Perhaps a bit larger for enough reserve, but you get the idea...

While I like the idea of a removable battery so we can fit a bigger one, the first link of 222Wh is maybe a bit overkill   Furthermore, this cell won't fit in the case. The other cells are way too small, or are really bare cells which you can't expect the buyer to fit themselves. Handling bare lipo cells can be dangerous for users who don't know what they're doing, so you would need a case where + and - can't be switched. Given the dimensions of the Pinebook Pro, it is physically too thin to provide a swappable battery
