I've let my 12V lead acid discharge thru a 50 ohm 10 watt resistor, it dropped pretty fast, but i only needed it to discharge it down to 10V. You can use a resistor size suitable to your battery voltage and current size. Lithium batteries are not "recycled" because they are hazzardous waste and might blow up or catch on fire.
The simplest option is a resistor of a few ohms. Even before the nominal 0% voltage, the battery's output voltage will collapse rapidly once it is nearly discharged, so I don't see any benefit in a more complicated solution. Do be aware that even fully discharged, the chemicals in a lithium cell can be pretty nasty stuff.
The internal resistance of the battery pack is made up of the cells, busbars, busbar joints, fuses, contactors, current shunt and connectors. As the cells are connected in parallel and series you need to take this into account when calculating the total resistance.
Resistor value for discharging the battery to 11V. It is given 25 C rating You need to show some effort in calculating this yourself and people will comment and help you refine that method. Otherwise this site becomes a homework answering service. I already did some calculations but I am confused whether the value are correct or not.
You should NEVER fully discharge a lithium battery. It ruins it. You should also NEVER discharge them fast as that will create internal heating which could cause them to explode or catch fire. I knew that question was coming!!!!
