The "4S" in a 4s lipo battery signifies that the battery pack consists of four individual Lithium Polymer lipo battery cells connected in series.Each of these cells has a nominal voltage of approximately 3.7 volts.When connected in series, their voltages combine, resulting in a total nominal voltage of 14.8V (4 x 3.7V).This is a significant jump from the more common 3s battery, which has a nominal voltage of 11.1V, or a basic lipo battery 3.7 v.

Depending on their properties and manufacturing methods, photovoltaic glass can be categorized into three main types: cover plates for flat-panel solar cells, usually made of rolled glass; thin-film solar cell conductive substrates, coated with semiconductor materials typically just a few micrometers thick on the surface of flat glass; and glass lenses or reflectors used in concentrating photovoltaic systems.
