kyradawg - A resistor will slow the discharge rate of a capacitor, but at a cost. Part of the energy of the capacitor will be lost as heat in the resistor. The key is to balance the resistance against the rate of discharge, so that the most gain can be achieved with the least loss of energy. But in the case of the battery/supercap combination, the relative internal impedances of the two provide a good balance already, so the addition of an external resistance will usually mean overall energy loss, with little gain in rate of discharge. It can be done, but since the internal impedance of the battery depends on its state of charge, age and temperature the balancing act would be tricky indeed. And one needs to remember that a shorted battery is nasty, but a shorted supercap is nasty squared. My 2600 farad supercap can generate over 30,000 amps if only for microseconds when shorted. This demands respect and caution at all times. As I mentioned earlier, trying to explain away the end of a wrench turned to a molten blob as normal wear and tear is a tough sell.
