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...

If you did have BMS cut-off, don't forget you will need a way to get the battery bank going again by recharging it. BB suggests you have a charger that can do that. EG my Vector smart charger will not do anything until the battery voltage is above about 5 volts, so it would not work on a cut-off LFP.
So first you would need to use a "dumb" charger. I think the converter would work, not sure. it would need power from a portable gen. Your installed gen needs a starting battery, but the LFP is cut-off and it might be the gen's batt where they use the House batt for that. Your inverter/charger would not work. It needs some battery voltage to operate at all, so its charger would not work. Solar if it happens in the daytime. Jumper cables from another good battery is a way.
