the experiment I would suggest

temperature sensors are never sitting at hottest spot and in this case they are sitting far away of this hottest spot I would expect in the middle of the cell.

now provoke a rapid thermal runaway by eg provoking short circuit in the center of the cell.

compare real temperature in the center of the cell with temperature measured at now given location to find out difference of these temperatures.

if measured temperature at given position eg shows 80 degrees when real temperature runs through critical tmperature adjust charging soft- or hardware and figure out how much energy content the battery still has compared to minimum required.

fly if still sufficient or go for bigger batteries...
