Re: voltage-torque curve

Per Eric's comment, the most common model for this is that battery's output impedance changes as a function of charge state (and age). For example, the battery could have an output impedance of 25 milliOhms when fully charged and new but could increase by a factor of 2 or more (very common to be even larger) when old or less than fully charged.
