What planet is Panasonic on?

Discontinued before they even hit these shores, and desperately needed for the GX7 body given the low capacity.
I use a Wasabi aftermarket battery as a back-up but remain terrified of it given a Comment from one reader that a like battery trashed his SD card when it was near empty.
It might be that B&H has a new part number for the battery.
I am skeptical to after-market batteries too, as many of them don’t report its charge level back to the camera; so I don’t get an indication whether the battery is getting flat or not. Neither does the camera, so it will just shut off abruptly when the battery runs out of juice. I have only gotten a few thrashed files; getting a thrashed SD card is worse, but in worst case (theoretically), one could end up with a trashed camera.
