Revisiting this thread as I completed my build, top balanced and now testing capacity. This is a 8s2p build with dual BMSs.
During testing, I realized I must have had a bad bms connection on one of the batteries (low voltage indicated on the bms application). I had issues initially with bad connections, but thought I had fixed everything. Apparently not.
Anyway, the BMS did its job and shut down the bank with the low voltage cell. Testing continued so the remaining bank in parallel took the load.
I just was working on the drawing today, so I'm open to comments. The fusing is kind of confusing, so I think the green arrows clears this up:

What Shunt are you using in this setup? If it is a Victron Smartshunt 500A,did you use "mid-point Wiering" (Vbat+ Aux) ? Oronly one the Vbat tomain possitive?
