A set of discharge plots vs. different charge voltages would be very useful.
Here is a good example.

I am using a CBAIII and testing some 160ah TS cells. What should the sag be if pulling 10amps? How about 20amps?

It's going to be tough to determine the internal resistance (Ri) data on a 200Ah cell if you can only load it at 0.05C or 0.1C. You are trying to measure a resistance in the milliohm range, and 10A across 1 milliohm results in 10mV of drop. You need a damn good meter to measure that accurately. If you can make the difference in testing currents at least 100A then even a crappy hardware store meter will let you make a decent Ri calculation.I am using a CBAIII and testing some 160ah TS cells.
