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...

Trillium has a sort of SOC gauge. (Rustofer said he has 110AH LFPs, so maybe these?) I don't know if it uses voltage and if it does, whether it can tell it is a loaded voltage vs resting voltage.
Using the Trillium's gauge, and wanting to know if it safe to start a 10 minute or so 100a load (on one batt) you would not run it if the yellow blinking lamp is on at 35% SOC and you wanted to be above about 32%.
With two of those batts with 220AH, now your 100 amp load is much less of a C rate, so you could pick a lower zone, but that 35 -20 is the same lamp. Solid red indicator to start off would be for the brave or desperate I guess. :)
IMO, I would rather have an AH counter to get a better idea of SOC.
