The best way to do a parallel setup is cell buddy-pairs if possible. There
is no problem doing it this way. Could also "cheat" with 2 separate
strings by tying the cell taps together as stiffly as practical.

Can't do in this case. Each module is a sealed box of 12s.

If it's sealed with no cell taps, how can you build a proper BMS?

I can get a cable in to do cell taps, but running a bunch of
cross-module interconnects that can carry high current is unlikely.
I'd need to use something like 16ga interconnects for between
module/cells. Then would I need to cross-connect with big cables at
each module pair, as well as cable t
Well, it depends on how closely matched the packs are. If they are good
quality and closely matched, then you don't really need the cell
interconnects between the 2 strings to be all that stiff. Consider that
most BMS balancing loads are 100ma or less, it's unlikely to have much more
than that f
Though, how will this setup works will depend on what kind of failure
happens.
One possible configuration would be with Big Cable cross connects at one
end of modules, and little cross connects between the 12 cells of the
module:
A) Single Cell Opens - in either module - All pack current com
