Interesting, though in the first thread there were problems with the battery gauge because of the added capacity, so it might not be a completely smooth affair.

If all that's required is that it's a 3.7V Lithium Polymer that fits into the DR1000s then Amazon.de should have some suitable batteries. I don't know about any Polish shops though, so that's the closest that I can think of.
