"Seems as if you could achieve a -2.4V (two 1.2V cells in series) bias with an internal resistance of less than 14 milliohms."
Maybe...
That 7 milli-ohm figure is a marketing number for electric vehicle
batteries. The other figure given in that chart (650 milli-ohms) is
very close to what I actually measure on 2 new AA NiMH batterise in
series in a battery bias circuit (1 ohm total). If you use these in
the cathode branch with 20 mA or so through them you will stabilize
at 2.8-2.9 volts in circuit.
These are all measured numbers
