How do I figure out max continuous discharging current of a battery?
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. If the battery data lists a continuous discharge current of 5A or more, you are good.
