receive the battery pack in at least two different orientations; and
couple the at least one battery cell of the battery pack to the electrical component of the power tool.
4. The power tool system of claim 1 , wherein the battery pack extends further in a first direction when attached to the power tool in a first orientation than when attached to the power tool in a second orientation.
5. The power tool system of claim 1 , wherein the battery pack distributes more weight toward a first side of the power tool when attached to the power tool in a first orientation than when attached to the power tool in a second orientation.
6. The power tool system of claim 1 , wherein the at least one battery cell comprises battery cells of a same diameter.
7. The power tool system of claim 1 , wherein the at least one battery cell comprises:
first battery cells of a first diameter; and
second battery cells of a second diameter that differs from the first diameter.
8. The power tool system of claim 7 , wherein longitudinal axes of the first battery cells are parallel to longitudinal axes of the second battery cells.
9. The power tool system of claim 1 , wherein:
the at least one battery cell comprises a first layer of first battery cells and a second layer of second battery cells;
each first battery cell has a first diameter; and
each second battery cell has a second diameter that differs from the first diameter.
10. The power tool system of claim 9 , wherein a longitudinal axis of one of the first battery cells is aligned with longitudinal interface between adjacent second battery cells.
11. A power tool system, comprising:
a power tool comprising an electrical component; and
a battery pack comprising at least one battery cell;
wherein the at least one battery cell of the battery pack is configured to supply electrical power to the electrical component of the power tool when the battery pack is attached to the power tool;
wherein a portion of the battery pack that comprises the at least one battery cell is configured to be inserted into a cavity of the power tool; and
wherein a footprint of the power tool and attached battery pack is adjustable via an orientation of the battery pack attached to the power tool.
12. The power tool system of claim 11 , wherein the power tool supports attachment of the battery pack in at least two different orientations.
13. The power tool system of claim 11 , wherein the power tool comprises a battery compartment configured to:
receive the battery pack in at least two different orientations; and
couple the at least one battery cell of the battery pack to the electrical component of the power tool.
14. The power tool system of claim 11 , wherein the battery pack extends further in a first direction when attached to the power tool in a first orientation than when attached to the power tool in a second orientation.
15. The power tool system of claim 11 , wherein the battery pack distributes more weight toward a first side of the power tool when attached to the power tool in a first orientation than when attached to the power tool in a second orientation.
16. The power tool system of claim 11 , wherein the at least one battery cell comprises battery cells of a same diameter.
17. The power tool system of claim 11 , wherein the at least one battery cell comprises:
first battery cells of a first diameter; and
second battery cells of a second diameter that differs from the first diameter.
18. The power tool system of claim 17 , wherein longitudinal axes of the first battery cells are parallel to longitudinal axes of the second battery cells.
19. The power tool system of claim 11 , wherein:
the at least one battery cell comprises a first layer of first battery cells and a second layer of second battery cells;
each first battery cell has a first diameter; and
each second battery cell has a second diameter that differs from the first diameter.
20. The power tool system of claim 19 , wherein a longitudinal axis of one of the first battery cells is aligned with longitudinal interface between adjacent second battery cells.
