Then we might as well ignore DC generators. If a generator is the answer, use an AC generator and:
a) a transformer to up/down the voltage so that you can rectify it to a few volts above pack and add capacitors
b) rectify it, run it through a DC-DC that will give you a few volts above pack.
If charging the batteries is not going to happen, you can use a diode between the generator's massaged DC output and the battery pack. It will draw from the generator till it can't keep up, then draw from the batteries. When load is low, the generator will ease up.
