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...

Any idea what the under-load voltage during this flat period would be?
I would hope LifePo4's could easily maintain at least 12.0v while under .5C - .6C discharge down to 20% SOC.
I hear lots of discussion about LifePo4 high charge rates at a given charge voltage, but very little discussion about discharge voltage while under heavy load. Got to have both to make the battery productive.
To answer this question - yes they should be able to maintain 12V under a < 1C load down ~10% SOC. Here is a typical discharge curve (multiply by 4 for a 12V battery):
