I have the following 26s bms:

I believe it's the same as this:
http://www.szsmartec.com/EN/productsview.asp?PID=833
It only has 26 balance leads (the full board is populated) for a 26s bms, and looks like it takes the first negative from the main B- port. Then the balance leads all go to the +ve side of the cells, but there's one more set of pads on the bottom right that I haven't figured out yet. Traces underneath (I'll get a picture later) look like it connects to the 26th cells +ve, so is this maybe the pack +ve or charge +ve or perhaps not even needed as the 26th cell +ve is connected?
Any advice my gurus of electrons?
