Does the voltage affect the AWG wire size choice?
Wire gauge is determined primarily by current. For example, a wire at only one volt, but carrying hundreds of amperes would need to be quite thick. Conversely, a wire carrying 1000V but a miniscule amount of current can be a smaller gauge but would need insulation rated for 1000V, so the insulation would be thicker than the conductor.

DOE Explains...Batteries | Department of Energy
Batteries and similar devices accept, store, and release electricity on demand. Batteries use chemistry, in the form of chemical potential, to store energy, just like many other everyday energy sources. For example, logs and oxygen both store energy in their chemical bonds until burning converts some of that chemical energy to heat.
