It's one of three or so connectors - no fan.

What connector? What do you connect there? I never saw anything like that on any of the pictures I saw about leaf batteries.

Pix does not show enough detail and it doesn't look like its a fan at all. Could be maintenance access port.

I found a better resolution pic:

Seems not to be a fan, but no idea what that could be, cause there are no such thing on battery packs which are dismounted from leafs on youtube. This should be something new on 40kWh pack?

Looking at the higher res pic it could be an emergency vent. I suppose a shrouded fan is also possible; if so it's a cooling fan for the BMS. It isn't big enough to be a fan to cool the modules.

Except that the BMS is on the other side of the pic after watching that video I linked. So that seems unlikely as well.

I thought the BMS was in the center rear...

Apparently not, These are both 24kWh packs & all have the BMS on the drivers side of the back corner of the pack. One is a 2013 & the other a 2011/2012

I have a white Vectrix VX-1 that was converted to Leaf modules by the previous owner. I didn't see the BMS mentioned in that first vid, but I'll take your word for it.
