You can wait a month or two and find out once mine arrive. Otherwise it seems like it will fit in the snes controllers, not 100% sure on the pro. Like all things, I don't expect a bigger battery to just fit in with no modifications required.
I have the SNES30, and it's fine. Wii mode and Wii U mode were a bit awkward, and have some input lag, but every other mode is fine. The D-Pad is slightly stiffer than a real controller, but that's about it. Battery life is still fantastic here after several months of ownership.
