New MMM V3 from RCM

I bought a MMM form RCM. last month.
I expected to receive an V3 esc with battery wire directly soldered to pc board.
However, what I received is with bullet connectors on pc board.
I though the bullet input is in early bench of MMM esc and should not appear in this time. (Maybe I do not remember correctly.)
Anyone has the same situation?
My esc works well, just out of curiosity.
