Default water resistant extended battery wtih NFC?

Does such a battery exist? I have been looking through several reviews of batteries and I don't see any that keep the water resistance. Not sure if this is a deal breaker for me or not.

Also in the past I have liked the Seidio set up since it seemed to be the only/best option for a protective case that fit an extended battery. It doesn't look like they have one for the S5 yet. anyone know if they are planning on introducing one?
