Battery Expansion Cable

I’m sorry if this has been asked and answered. I have an AC200PL and two B300K batteries. The batteries came with a connection cable but they don’t connect to the AC200PL - just to each other. The user manual shows an optional cable with “B210P Expansion Cable” as the description. Amazon has a battery expansion cable called " BLUETTI P090A Battery Expansion Cable". Is that the cable I need to connect the power station to the first battery?

Yes the P090A cable is what you need to connect the AC200PL to the first battery. N.B. The cable isn’t long enough to stack the AC200PL on top of the batteries with all three units facing the same way, due to the power station and the batteries having their connections on different sides.

So I can stack the batteries, but the power station will have to be set to the right of them. I think I can plan ahead for that. Thanks.
