I got you Electric eels have three sets of internal organs that produce electricity. The organs are made up of special cells called "electrocytes." Electric eels can create both low and high voltage charges with their electrocytes. Electric eels generate their electric shocks much like a battery. Like the stacked plates of a battery, the stacked electric cells can generate an electrical shock of 500 volts and 1 ampere. the brain sends a signal through the nervous system to the electrocytes. This opens the ion channels, allowing sodium to flow through, reversing the polarity momentarily. By causing a sudden difference in electric potential, it generates an electric current in a manner similar to a battery, in which stacked plates each produce an electric potential difference.
