Continuous discharge is very important. Actually one of the most important parameters, more so than Ah, not less so.

Up until recently this has been the case with LiFePO4 batteries but as the cells improve, the discharge current has been increasing compared to the capacity rating.
The relationship between capacity (Ah) and continuous current rating (A) is known as the “C rating”. A 1C rating is fairly common for cheap cells. Better (read more expensive) cells may have a 3C or even 5C rating. A 100Ah 5C battery can discharge at 500A continuously.
