Of course, such a bank should not be built by paralleling strings, imbalance issues are inherent in such layouts.
3.2V cells at the target Ah capacity, all in one string is preferred, each cell gets monitored and balanced properly by the one master BMS. In this case 16* 100-150Ah cells in series.
If not possible (why not?) then put the lower-Ah cells in parallel groups at the bottom level, then connect in serial to get to the desired voltage, e.g. 2P16S, 2*60Ah *16 in series.
But then you're not able to monitor at the per-cell level.
Having multiple "sub BMS" connected without central coordination increases the complexity geometrically, unreliable may even be dangerous.
What are the exact batteries used? BMS? Links please.
Who advised you these units could be used this way?
Also a more detailed diagram of the wiring layout. For example are these BMS common-port type, or separate ports for charge vs discharge?
