What is Ah in Battery Capacity?
Battery clusters are used to increase the overall capacity and power output of a battery system. By connecting multiple batteries in a cluster, the Ah rating can be increased to meet the specific energy demands of the application. It represents the number of amps of current the battery can deliver over an hour before it is fully discharged
