per this post, you're supposed to be getting SE cells with some 0.6 mR internal resistance, or 24 mV/C. That's radically different to what has been measured above.
Our cells are at Brisbane port, so yours may not be far off.
I don't suppose you've actually got yours and had a chance to make an IR measurement, have you?
I have an arrival notice that says they should be available for collection next Tuesday.
The QC report they sent quotes internal resistances of around .55 - .6 milliohms and capacities of 47 - 48 AH measured at .1C discharge.
I'll be very interested indeed to see if those figures stack up!
They also quote an open circuit voltage of 3.3v at the state of charge the measurements were done at (and 20 deg C ambient).
That means that if I suck 200A out of one, the voltage drop should only be .12v ie the terminal voltage will be 3.18! Believe it when I see it....
