LifePo4 Voltage at .5C - .6C Discharge
Our two GC2's (with 100% charge) drop below 12v while under a 100a - 125a load. When they reach 50% (at 100a - 125a), voltage drops into the low 11's while under-load. What kind of under-load volt...

That voltage drop is from a combination of wiring and battery. How much of the drop is due to the wiring? When you go to LFP that will help reduce the battery part of the drop AFAIK, but is there any change to the wiring when you swap them?
Besides the wiring to charging and loads, on the battery bank now there is the one series link this is part of the loss. The LFP cells have low R, but are connected with lots of wiring. Apparently some LFPs have better wiring than others that could affect voltage drop. You might have to specify which LFP to make an accurate comparison--not sure--that came up in the video where the guy rook apart an LFP and was commenting on its wiring.
