1. A battery pack for a vehicle, the battery pack comprising:
one or more batteries configured to provide a first voltage, the one or more batteries comprising a first battery subassembly and a second battery subassembly;
first circuitry configured to provide access to the first voltage from the one or more batteries by a drive component of the vehicle; and
second circuitry configured to receive the first voltage from the one or more batteries and to provide access to a second voltage, lower than the first voltage, by one or more electrical components of the vehicle, the second circuitry comprising a first direct-current-to-direct-current (DCDC) converter and a second DCDC converter, wherein:
the first DCDC converter is configured to receive the first voltage from the first battery subassembly and is electrically isolated from the second battery subassembly, and
the second DCDC converter is configured to receive the first voltage from the second battery subassembly and is electrically isolated from the first battery subassembly.
