Battery constant power discharge diagram
A 1C rate means that the discharge current will discharge the entire battery in 1 hour. For a battery with a capacity of 100 Amp-hrs, this equates to a discharge current of 100 Amps. A 5C rate for this battery would be 500 Amps, and a C/2 rate would be 50 Amps. Similarly, an E-rate describes the discharge power. A 1E rate is the discharge

Education
Some guesswork is involved, so a good rule of thumb is to add another 5% or 10% as a design safety margin. For a constant power discharge, you could use the current at the end of discharge; this is the most conservative approach. Or you could use the constant power discharge curves, if the manufacturer provides them.
