Hi, I am relatively new to raspberry and I need my raspberry to run on batteries for a project Im working on. After looking online for solutions I found many different batteries that run on different voltages with a variety of additional boards, if anybody could give me an explanation about the differences or just a link to a know good product, that would be fantastic.
Short version.... The Pi wants a steady 5v at up to 2.5A. There are no 5v batteries that I know of, so you will need a voltage converter from whatever the battery puts out to the 5v the Pi requires. Some battery systems (such as "powerbanks") have the voltage conversion built into the battery case. Nominal battery voltage (voltage goes down as the battery discharges) is determined by the cell chemistry and the number of cells.
