E-Moli IMR-18650E cell have nominal voltage of 3.8 volt and 1400ma this give a 5.32w/h, output 20Amp discharge
dischage rate give you the torque possibility of battery,but the real workhorse is the watts/hour it give you the real capacity of the cell,the power output in the time.
you can make the cost per w/h of battery yourself
have a nice day
