## Main Question or Discussion Point

Hi. How would you calculate the total electric potential energy of a battery containing two cells (just an example), with for instance 20 V (cumulative, if cells are in series) and runs on a 60 A circuit.

Is it required to have the charge of the battery to calculate total energy in joules?

The whole point of this is to calculate how long a 100 W motor would run on a certain combination of batteries.

(By the way, these are all hypothetical situations)

Thanks
