GH13 Generic batteries working with GH13 ?

[Fukurou]

So, yeah, I'm looking for a generic battery working with the GH13.
I heard about some firmware problems, some generic battery not working if you do not have the right firmware, so I'm wondering if there's any available battery working with a GH13 displaying "version 0.0".

I founds this.
Anyone heard about it, or something better ? (knowing that it should ship to Europe)

Edit : oh, and while I'm at it, the seller have this cheap charger too :

Any feedback on this one ?

Oh well, never mind, I ordered and got them, and both seems to be working perfectly fine.
Of course, at this price, I'm guessing problems could occur in the future, but heh, for now, that's hell of a good bargain.
