1. A battery management and monitoring system integrated in a battery pack configured for use in electric aircraft, the system comprising:
a sensor suite configured to measure a plurality of battery pack data, wherein the sensor suite is further configured to detect a cell failure of a battery cell of the battery pack;
a battery monitoring component, the battery monitoring component configured to:
detect, during a flight of the electric aircraft, as a function of the plurality of battery pack data, a first fault in the battery pack; and
produce a first fault detection response notifying a user of the first fault in the battery pack;
a battery management component, the battery management component configured to:
detect, when the electric aircraft is grounded, as a function of the plurality of battery pack data, a second fault in the battery pack;
a second fault detection response configured to receive the plurality of battery pack data, wherein the second fault detection response is configured to mitigate the fault in the battery pack; and
an interlock component having a first mode and a second mode, the interlock component configured to:
enable the battery monitoring component and disable the battery management component when in the first mode; and
enable the battery management component and enable the battery monitoring component when in the second mode.
