Eco mod my welder

My newest welder ecomod is to power my mig welder off a 2000 watt samlex pure sine wave power inverter and my 60 amp hour LiFePO4 battery.
I tested it on my 40 amp hour battery, then expanded it to 60 amp hours, a mod I have been sitting on for too long.

My 40ah AMP20 cell battery had just enough power to run the power inverter with the welder on it at full power for a shot time. Problem is the battery had to keep the voltage above 10.5v at the inverter.
