When you check the cells, you will find the "8V cells" are actually 2x regular Li-ion cells in series.
You use a regular 3.7V BMS like Batrium & have to wire to each 3.7V cell.
So you would end up using a 7S BMS

In that case you will use 4 "8V cells" of which u use 1 only half.

See this image showing a system with a 6P arrangement & Batrium "leafmons":

If you do a search on this site (top right) for "leaf" you'll see how others have used & connected them :-)

Exactly how you connect them depends on how many of the 2cell-in-1 block units you have.

Like RikH says, odd cell numbers might not be the best use of your packs, maybe consider a 48V system = 14S (use all the cells)
