1. A system for state determination of a battery module configured for use in an electric aircraft, the system comprising:
at least a battery module, the at least a battery module comprising at least a battery cell;
at least a sensor configured to detect a physical change in dimension of at least a battery cell within the at least a battery module;
a processor configured to:
generate a health metric based on electrical data of the at least a battery module, and the physical change in dimension of the at least a battery module detected during operation of the electric aircraft;
compare the health metric to a threshold value of the health metric, wherein the threshold value indicates an ideal operating condition of the at least a battery module; and
determine, based on the health metric, a battery performance level of the at least a battery module relative to the ideal operating condition.
