You are free to do what you like. I tend to take the advice of people who have more experience than I have.
Here is an excerpt from:

"Single 3.2V prismatic LiFePO4 cells can nowadays be obtained in huge capacity, as high as 10000Ah. Commonly available cells range between 40Ah and maybe 1000Ah. It should be pointed out that the larger sizes are intended for stationary applications where no accelerations, vibrations or shocks are ever experienced.
A sales manager at Sinopoly I was talking to was
adamant about using
100Ah or 200Ah cells only for assembling marine battery banks, with 100Ah being preferred and 200Ah acceptable. Large cells simply don’t have the structural strength-to-weight ratio required to be taken to sea on board small crafts and would exhibit shortened life due to internal mechanical damage arising from on-going vessel motion. It is common sense: as a cell becomes larger, its internal weight increases
much faster than the rigidity and surface area of the casing and the casing is all what holds the plates together in a prismatic cell."
