Maximum 30-sec Discharge Pulse Current –The maximum current at which the battery can be discharged for pulses of up to 30 seconds. This limit is usually defined by the battery manufacturer in order to prevent excessive discharge rates that would damage the battery or reduce its capacity.
The battery discharge rate is the amount of current that a battery can provide in a given time. It is usually expressed in amperes (A) or milliamperes (mA). The higher the discharge rate, the more power the battery can provide. To calculate the battery discharge rate, you need to know the capacity of the battery and the voltage.
The charging conditions of the battery: charging rate, temperature, cut-off voltage affect the capacity of the battery, thus determining the discharge capacity. Method of determination of battery capacity: Different industries have different test standards according to the working conditions.
There is no generic answer to this. You read the battery datasheet. Either it will tell you the max discharge current, or it will tell you the capacity at a particular discharge rate, probably in the form C/20 where C means the capacity. You know the current you need : 4.61A.
As the rate of discharge increases, the battery's available capacity decreases, approximately according to Peukert's law. Manufacturers specify the capacity of a battery at a specified discharge rate.
The faster a battery can discharge, the higher its discharge rate. To calculate a battery’s discharge rate, simply divide the battery’s capacity (measured in amp-hours) by its discharge time (measured in hours). For example, if a battery has a capacity of 3 amp-hours and can be discharged in 1 hour, its discharge rate would be 3 amps.
A C/2 or 0.5C rate means that this particular discharge current will discharge the battery in 2 hours. For example, a 50Ah battery will discharge at 25A for 2 hours. A similar …

For a typical 6f22-form factor battery it is something 2-20 ohm for a new battery at room temperature. It gets higher as the battery gets discharged, rises with discharge current …
We can also calculate the maximum current we can draw taking the cell down to the minimum voltage: 2.5V = 3.7V – I x 0.025Ω. Rearranging this we can calculate the current: I = (3.7V – 2.5V) / 0.025Ω = 48A. These …

To choose a minimum capacity battery use the 1C rate on small cells ie. Ah capacity remaining/ 1h and worst case impedance e.g. Vmin/IMax=3.2V/0.3A=≈10ohm load …
A C/2 or 0.5C rate means that this particular discharge current will discharge the battery in 2 hours. For example, a 50Ah battery will discharge at 25A for 2 hours. A similar analogy applies to the C-rate of charge.
The internal resistance of the battery increases with the increase of the discharge current of the battery, which is mainly because the large discharge current …
Standard discharge current is related with nominal/rated battery capacity (for example 2500mAh), and cycle count. If the battery is discharged with a higher current, the real …
