Discharging a single cell is not as easy as it would seem, well discharging it quickly at least. You could easily discharge one with a cheap lipo charger that also has a LiFe setting but they usually only discharge at 20-25W unless you pay $100+ for a decent one with either regenerative discharge or discharge+ feature. so at best your going to be looking at a 5-7amp discharge rate. even the element from a 1000watt space heater would only pull about 30watts from the cell at 3.3v. About best way i can think would be a high wattage, low voltage step up DC/DC converter to step it up to 12V, then you would have no problem pulling 20-30 amps out of it with the right converter.
Any more than 20-30 amps and then your looking at a lot of $$$ just for the discharger, i once watched a youtube vid of someone pulling 300amps from a single A123 20AH pouch with a massive resistor the size of beer keg, no idea where they got it from though.
