The old "were do I put my registration sticker" problem. According to the section "I. Executive Summary", the battery compartment is OK if it is easily accessible without using a tool.

To grant flexibility to the diverse types of small unmanned aircraft commercially available, the FAA required that the registration number marking be readily accessible and maintained in a condition that is readable and legible upon close visual inspection. The IFR further explained that markings in an enclosed compartment, such as a battery compartment, will be considered readily accessible if they can be accessed without the use of tools.


I had asked the FAA a few days before the shut down this very question and the FAA responded just recently with:

Of course the above would be acceptable if accessible without using a tool.
