Note: You really do NOT need to tie the center posts to anything other
than a BMS. Even with cells in parallel.
In my leaf pack I had a 3 Parallel x 16 Series battery pack.
I tied each of the 3 "sense" center posts together for each set of 3
cells. [The only thing these tied together center posts were connected
to was my BMS....but I did tie the 3 center posts together.]
How would your BMS work if it was not connected to the center posts?
Did you connect to only 1 of the 3 center posts in my example? (I was
worried that if I did this the bms itself would draw more current from
one of my 3 leaf modules than the other two, causing them to get out of
balance with each other.
