A diode, such as 1N5817, is recommended to prevent the solar module from draining the battery when the solar panel is in the dark. No diode is needed for a battery free electrical device. The recommended connector wire size is 24 gauge. Before use connect the solar module to a digital multimeter for polarity identification.
DO NOT CONNECT A CHARGED BATTERY BACKWARDS OR REVERSE POLARITY TO THE SOLAR MODULE, THIS WILL DESTROY THE MODULE AND MAY CAUSE THE BATTERY TO EXPLODE RESULTING IN BODILY INJURY OR DEATH.
