Stacked battery components and configurations

A battery, comprising:

• a first battery cell comprising:
• a first body characterized by a first length and a first width, and
• a first tab extending from an edge of the first body, wherein the first tab is characterized by a width less than the first width of the first body;
• and
• a second battery cell stacked below the first battery cell, the second battery cell comprising:
• a second body characterized by a second length and a second width, and
• a second tab extending from an edge of the second body, wherein the second tab is characterized by a width less than the second width of the second body, and wherein:
• the second tab is characterized by a width greater than the width of the first tab providing an extension of the second tab protruding from below the first tab;
• and
• wherein a first voltage sensor is coupled with a surface of the first tab, and wherein a second voltage sensor is coupled with a surface of the extension of the second tab.
