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...

otrfun,
Using a 12 volt form factor rather than twin 6 volt batteries improves greatly on voltage drop under load, simply because there are twice as many cells.
Some LI battery management systems limit discharge rate to 1 C.
There are a host of other hoops to jump through with LiFePo4.
That said, the LI chemistries behave much like the old Nicads--where they supported the voltage well and then dropped off a cliff.
My next battery bank will be SiO2 chemistry because they meet my needs, do not sulphate and there are many fewer hoops to jump through.
Any battery type can be designed to fit the needs of a particular end user.
Please wire your new bank in a balanced manner.
