Default BMS Wiring for my Leaf Pack

I have a 57V 120AH 14S Leaf battery pack pictured below.
I am adding a chargery BMS to it. The BMS supports up to 24 cells, but I am using 14 cells.

I am hoping for guidance on the BMS wiring. Please be gentle, I am doing my best.

Starting from Right to Left in Picture.
BMS Bank #1:
BMS -1 --> Module 1 - Bottom Post (Main Negative Out)
BMS +1 --> Module 2 - Center Post
BMS +2 --> Module 3 - Top Post
BMS +3 --> Module 4 - Center Post
BMS +4 --> Module 5 - Bottom Post
BMS +5 --> Module 6 - Center Post
BMS +6 --> Module 7 - Top Post
BMS +7 --> Module 8 - Center Post
BMS +8 --> Module 9 - Bottom Post
-----
BMS Bank #2:
BMS -9 --> Module 9 - Bottom Post
BMS +9 --> Module 10 - Center Post
BMS +10 --> Module 11 - Top Post
BMS +11 --> Module 12 - Center Post
BMS +12 --> Module 13 - Bottom Post
BMS +13 --> Module 14 - Center Post
BMS +14 --> Module 14 - Top Post (Main Positive Out)

Thank you for the reply Sir. I did review that diagram carefully, but it appears to be a different pack configuration (4s+4s+6s), which is why I choose the other diagram showing it in series.

You have 14 cells and this is the drawing they provide with the BMS 24 for 14 cells. Wiring wound be different if this were a BMS 16, and would be better suited here.

My apologies Sir, I did misspeak. My BMS is the 16, NOT the 24. I was confused as the manual is for both. My BMS only has the two ports. Is my diagram correct for the 16?

It makes no difference if there is a buss-bar or a piece of cable connecting the modules, all of those diagrams posted and referenced are exactly the same.

You always start with the first connector and don't go to the next one until all ports are connected.

The reference on the next connector (first tap) goes to the same location as the last tap on the previous connector.

Your connection description in the first post is correct.

I am with Sergio completely and that your connection description was correct. My reference was for the 14S connection diagram.

I know this post is a few months old, but I'm having trouble wiring my BMS. Can you tell me whether this is correct? I based it off his description in the first post. [IMG][/IMG]

That looks correct, I assume You are splitting it into 2 separate packs correct?

If so keep that cable that connects the packs as short as practical and make sure both of the BMS wires 8+ and 9- connect to the same terminal as You have it drawn.
