1. A system comprising:
- a plurality of galvanic cells having electrical cell connectors, the electrical connectors each having;
a planar base section extending longitudinally and having first and second opposite longitudinal edges;
a planar, first connecting tab connected to the base section on the first longitudinal edge thereof, a plane of the first connecting tab being aligned at a right angle to a plane of the base section; and
a planar, second connecting tab connected to the base section on the second longitudinal edge thereof, a plane of the second connecting tab being aligned at a right angle to a plane of the base section, wherein the first connecting tab and the second connecting tab are arranged offset with respect to one another in the longitudinal direction of the base section in a stacked formation of the galvanic cells,wherein the first connecting tab and the second connecting tab define an overlapping region in the longitudinal direction of the base section.
