What is the 'voltage sag' at max amps ?

Tesla battery modules are good for 850Amps and as high as 1500Amps for a few seconds,
But at these currents what does the voltage get pulled down to ?

I've heard voltage sag of 2.7-2.8V per cell, ie 260v - 270v per 16 module S85/90/100 battery is acceptable in short bursts.
does anyone have any more information on this ?

Could the cells sag as low as say 2v ? ...... just for a few seconds, without damage (assuming SOC is above say 30% and temperature 15degC to 35).
