It would help if you pasted the push output. For example, does it stop
at 20% at the "compressing objects" line or "writing objects". How
many total objects does it say?

Another question is how big are these binary files on average? Git
considers a file is "big" if its size is 512MB or more (see
core.bigFileThreshold). If your binary files are are mostly under this
limit, but still big enough, then git may still try to compare new
objects with these to find the smallest "diff" to send. If it's the
case, you could set core.bigFileThreshold to cover these binary files.
