Can the battery calculated internal resistance value (ESR) be read?

I know that later versions look at battery ESR (droop) when the system takes off, and uses that value to for compensation on the “BATT LOW” and “BATT CRITICAL” failsafes, but is that ESR value (millivolts/Amp) available somewhere that I can later read?


It is saved in the flash log. As far as I know, it is not transmitted via Mavlink.
