I've not yet set the modules up for testing, but I will have several tests to do by the weekend. The one module have already built is to be the 'spare' module, and it's just as well because the thermal epoxy doesn't have the sort of coverage I'd like it to have. It's probably 90 % as good as it needs to be.
However I found some Tesla pack data:

So this is a 1.2 C discharge on a Tesla Model S module. The measured internal resistance is about 100 mOhm per cell (remembering there are 74 in parallel and 6 of these in series - so the overall internal impedance of the pack is 0.0081 Ohm. At 297 amps it was generating 715 W of heat - for the first 30 seconds anyway. It dropped off as the voltage dropped.
The heat generation is plotted, as is the delta T in the coolant. From the delta T in the coolant we can infer the heat absorbed by the coolant.

It's rough, but should give some idea. Hope to have my data soon.
