BK 12020 esc wires ques

When I purchase my new 12020 esc, I saw that there are four battery leads, 2 black and 2 red. I have batteries that also have 2 Black and two red (this is 2 3s2p packs in SERIES)). Can I just match the leads of the batts with the leads of the controller and get a SERIES electrical setup?

Thanks!
