An electrical system can include a power supply configured to provide electrical power to components at a time at which the electrical system experiences an electrical fault. The electrical system can include a first battery electrically coupled in parallel to a second battery via an electrical bus, whereby the first and second batteries can provide electrical power to a first electrical load and a second electrical load. Upon experiencing a fault, a first circuit element can electrically decouple the first battery and the second battery by opening a circuit provided by the electrical bus, thereby isolating the first battery from the second battery. Next, the battery experiencing the fault can include a second circuit element that can electrically decouple the battery experiencing the fault from a respective electrical load, while the battery isolated from the fault can continue to provide electrical power to components.
