What is the 'voltage sag' at max amps ?

[Mark77a]

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).

260 volts is what my 1525 amp P85DL makes at 30% and 110F. So you're right on the money.
