Connector Deye RW-M6.1

I am looking for the spare connectors for the Deye RW-M6.1 batteries (first generation, not the B variant). See attached image.

These connectors are being used if you want to crimp your own cables.
I contacted some shops, but they don't have them.
I contacted Deye, but they don't answer.

Does anybody know where I can get them?
