Battery question, I am building a 7s 20p battery. The box I have requires me to use two modules. What is the best way to connect the modules?

Battery question, I am building a 7s 20p battery. The box I have requires me to use two modules. What is the best way to connect the modules? Each module contains 7 series rows. Would it be better to connect each series row together and if yes what is the recommended method or would it be ok to connect both modules in parallel and add a second BMS?
thx

Assuming 3.7V nominal
7S for "24V" system.

You would take 10 cells, put them in parallel to make one big 10P cell, do this 14 times. Then build two 10P7S batteries with a BMS on each one.
