Dude, please, I now don't even know what your problem is about. That guy in the video powers one GPU with an extra power supply, just as I mentioned above it's possible. It's still a big "be careful!" and a stronger power supply is still more than recommended
A battery btw. is electrically completely different to a PSU. Each battery has a closed curcuit and no shared negative pole.
Just read this FAQ if you're still thinking about it:
