Wow! Thank you! That adds a lot more variables than I realized. I'll do another test now that I have the battery fully charged.

Yes, I understand that part, I was wondering about the voltage drop under heavy loads.

Thanks for this - so, at 135 A the drop was to 12.5 volts, so (13.3-12.48)/135 = 6mOhms. Is that a typical internal resistance for 280AH LFE battery? Connections are nice and tight. I'm measuring right at the battery terminals. I didn't try to measure at the inverter inputs, as I know that there...

I am just starting out with a 280AH LiFePO4 battery, after having used some flooded lead-acid for a couple of years. I've looked online to see if I could find some info on how low the battery terminal voltage should drop under load, but haven't found anything other than generalities. With a...
