Lead-Acid Batteries Voltage Sag Formulas

Hi everyone, There seems to be a number of people responding to the Electric Car threads, so I wondered if anyone knows of some formulas that can be used to determine - ahead of time - how much the voltage will sag on a Lead Acid Battery, under some specific load or varying load?

While I have a PakTrakr - and a Woodward Enhanced PakTrakr Display - with Data Logging - I have a lot of empirical data, but no formula - maybe someone can look at the data and come up with a formula?

Electricfly - and NoGas96volts

Thanks for you help, ahead of time! Robert
