1. An internal combustion engine, comprising:
an engine block including a cylinder; a piston positioned within the cylinder, wherein the piston is configured to reciprocate in the cylinder along a cylinder axis; a crankshaft configured to be driven by the piston; a fuel system for supplying an air-fuel mixture to the cylinder; and an electric starting system including a starter motor, a battery receiver, and a lithium-ion battery removably attached to the battery receiver, wherein the lithium-ion battery is configured to power the starter motor to start the engine, wherein the lithium-ion battery includes at least one lithium-ion cell having a cell axis, and wherein the battery receiver is positioned so that with the lithium-ion battery attached to the battery receiver, the cylinder axis and the cell axis are not parallel to one another; wherein the crankshaft is a vertical crankshaft and the battery receiver is positioned above the crankshaft; and wherein the battery receiver comprises a receptacle for receiving the lithium-ion battery and an air intake for allowing air to flow to the engine block.
