An electric aircraft has a fault-tolerant electrical system designed to optimize competing concerns related to cost, performance, and safety. An electrical system in accordance with some embodiments of the present disclosure has a plurality of power sources (e.g., batteries) that are connected to other electrical components, such as motors for driving propellers or flight control surfaces, by a plurality of electrical buses. Each such bus is electrically isolated from the other buses to help the system better withstand electrical faults. Further, one or more of the electrical buses is connected to motors for driving multiple propellers. Selection of the propellers to be powered by energy received from the same bus is optimized so as to limit the effect of an electrical fault on the stability and controllability of the aircraft.
