ABSTRACT:
A lighting system is provided that includes at least one lighting device, at least one connector, and a plurality of external power sources. The external power sources are adapted to be electrically connected to the lighting device by the connector. One of the external power sources is an energy storage system having a plurality of battery cells. A first charging method is utilized when a voltage potential of first and second battery cells is less than a voltage potential threshold, a second charging method is utilized when the voltage potential of the first and second battery cells is equal to or greater than the voltage potential threshold, and the first charging method is utilized to charge the first battery cell prior to charging the second battery cell when the first battery cell voltage potential is below the voltage potential threshold and greater than the second battery cell voltage potential.
