are empty, is placed on the pedestal.
= more spacing outside the modules, including an accessible central aisle on the keel
= the LIBs' front facing the aisle, and
= a 6 by 6 row of LIBs arranged in clusters on each side of the aisle.
Batteries on pedestals have the downsides of a higher center of gravity (maybe increasing vibration and top-heaviness) and may expand any stray magnetic field. But mounting LIBs on pedestals has the benefits of providing better access for installation, maintenance and removal.
necessary, partly achieved by rearranging some fuel and buoyancy tanks.
