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...

Appreciate everybody's inputs. Always learning something new.
Called LifeBlue (lifebluebattery.com) on Mon and inquired about the voltage drop with their 100ah LifePo4 battery while under heavy load. Surprisingly, he offered to test one and get back with me. Received an email yesterday with the results. With a fully charged battery, battery voltage was 12.8v at 80a, and 12.7v at 100a. Pretty impressive. Based on the graph FWC posted, I'd guess-estimate battery voltage while would drop to approx. 12.0v at 15% SOC with a 100a load.
