Hallo
its nice to have an 2cell accumulator. (selsect Power Supply-->Battery)
However, whats about 1, 3 and more?
That would be nice to let me choose how many cells are in
I wish a selextorbox to select 1,2, up to 10cells in row.
Thats would be a useful lib entry
thanks a lot

Hi lutzd,
If you open an schematic or symbol canvas and do:
Shift+F
and then search for "battery" or "cell" you will find several symbols such as you are requesting in the library.
If you can't find exactly what you are looking for, you can easily draw your own:
