Yeah I wondered about the "real life" meaning of this draw down test and tried to ask but there was a lot of folks and distraction going on. since Dave Cloud's focus is racing, drag and endurance, I would guess it has more meaning/application to him than it does to us with our etraks... However I don't think a car battery is ever meant to be drawn down to 10volts is it?
For Drag racing it might make sense. That'll be a short run at high current all the way (hopefully).
10V on the battery, that will be 1.67V per cell. If that's while drawing 400A then It's not too much of a dip . Even at 5 milliohms 400Amps is a 2V drop.
At rest that would be a low voltage, but it would not be meaningful immediately after the current was removed. The battery will need some time to recover.
