An aerial vehicle may receive electrical power from power modules that may be installed into or removed from the aerial vehicle during flight operations. Such power modules may be inserted into a chamber from below the aerial vehicle and may come into contact with one or more terminals or leads for powering propulsion motors or other electrical loads. Such power modules may also be removed from above the aerial vehicle, thereby uncoupling the power modules from the electrical loads. Power modules may be installed into or removed from a chamber using tension members that are guided into the chamber from lateral slots extending between a perimeter of the aerial vehicle and the chamber. The tension members may be used to not only engage and remove a power module within the chamber but also to install a power module into the chamber.
