High power distribution architectures

A power distribution system for an aircraft, comprising:

• a plurality of electric propeller units (EPUs);
• a first paired battery pack unit, the first paired battery pack unit comprising a first battery pack electrically connected to a second battery pack via a first battery pack cross-link, wherein the first battery pack is configured to provide power to a first set of EPUs of the plurality of EPUs, wherein the second battery pack is configured to provide power to a second set of EPUs of the plurality of EPUs;
• and
• a second paired battery pack unit, the second paired battery pack unit comprising a third battery pack electrically connected to a fourth battery pack via a second battery pack cross-link, wherein the third battery pack is configured to provide power to a third set of EPUs of the plurality of EPUs, wherein the fourth battery pack is configured to provide power to a fourth set of EPUs of the plurality of EPUs.
