I have used LiFePO4, CALB and Thundersky. LiFePO4 has been around for quite a while. It has been run without BMS (I do that) but that's not the discussion topic here.

From a bit of reading, the LiFeMnPO4 seems to be a LiFePO4 with Mn and other things used as an additive. Perhaps it gives more cycles, or prevents dendrite formation, or something like that.

Using EVTV as a comparison, 48 *100 a-h cells * $135 = $6480
straps at $10 each * 48 = $480

That's $6960, so $7990 is a bit higher but I don't know that the CALB cells are a good comparison.

The bms and charger are extra so you can get whatever you like for that part.
In THEORY there is no difference between Theory and Practice
