Isnt it because fuel can be dumped in an emergency, if needed? Cant say the same about batteries.

  Ultralight airplanes, and any general aviation plane I know of, do not have fuel dump systems. In cases where a plane is too heavy to land, it will often circle for a few minutes to burn off excess.

  Not really an option for ultralights or most private aircraft.

  But what happens "magically" at 255 pounds of weight that it falls in another category?

  The risk is different a large volume of liquid that can spill and is volatile vs essentially a solid (yes electrolyte is liquid/gel).

  Batteries aren’t flammable liquid that sprays all over the place and ignites in a crash.
