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...

I am not sure what your obsession with this is, but as we have tried to explain before, you cannot use voltage to determine the SOC for a lithium battery. Anyone who with experience with lithium batteries knows this.
The only successful device that used voltage to determine state of charge for lead acid batteries (smartgauge) doesn't work for LI chemistries. It probably never will, even though it checked voltage 60 times per second. So other than that "one" device, voltage is a pretty poor way to "guess" at state of charge for most battery chemistries.
All the other meters 'drift' over time because capacity is a "moveable feast" being affected by temperature, load and age.
What is your experience with Li?
