This definitely looks like an interesting project.
Wow - do I understand this correctly? -
You're setting up 48 pairs of 3V, 100AH cells, so each pair is 200AH.
Putting the 48 pairs in series gives (nominally) 144V.
That's a lot of cells! And they're not small. Should be a very nice pack.
I suggest you post your offer in our "Fossil Fuel Free" sub-forum.
I would guess that anyone on this site interested in battery projects of that size will go there regularly.

Good luck with both building and selling!
I used a pack of 4x 3.2V 40AH LiFePO4 cells in series, to power headlights and fans on my gas powered Civic and Accord. It weighs in at 16.2 lb. including a small BMS. Looks like your 96-cell pack will weigh in at something like 700 lb!
