Can a Li-ion battery be discharged in CV mode?
A step change of just 5mV difference to the terminal voltage would produce an instantaneous current of 1A, and 500mV would cause an instantaneous current of 100A to flow. The very low source impedance produces large variations in current for small variations in voltage - it is better to control the current until the voltages have stabilised.

In this case, the discharge rate is given by the battery capacity (in Ah) divided by the number of hours it takes to charge/discharge the battery. For example, a battery capacity of 500 Ah that is theoretically discharged to its cut-off voltage in 20 hours will have a discharge rate of 500 Ah/20 h = 25 A.
