delta for first graph was 20 deg F and 2nd was 50 deg F (125 deg F max) ]
The battery should really be able to be pulled a bit harder and will be a nice 12-15 C constant battery. It would be unrealistic to expect the full capacity at the full current. Full capacity shall be listed at very low current. sorry, that's the way it is.

2nd graph is 14.2 C (not 7.5 c)
The third graph is now up at 120 amps and 28.5C and forced cooling on cell so it doesn't overheat. It looks pretty good at 3.1 volts average and the discharge isn't flat yet.
It's a shame not many are currently testing cells anymore to compare them.
