Maximum Continuous Discharge Current – The maximum current at which the battery can be discharged continuously. 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.
To illustrate how this formula works in practice, let’s consider a hypothetical scenario where we have a lithium-ion battery with a capacity of 2000mAh (or 2Ah) and a C rating of 20C. Applying the formula I = Capacity x C rating, we can calculate that the continuous discharge current would be: I = 2Ah x 20C
The maximum continuous discharge current is the highest amperage your lithium battery should be operated at perpetually. This may be a new term that’s not part of your battery vocabulary because it is rarely if ever, mentioned with lead-acid batteries.
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.
Capacity represents the total amount of charge stored within a battery, while the discharge current dictates how quickly this charge can be released. The relationship with C rating lies in defining how much current can be safely drawn from the battery over time.
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.
