You didn't say whether your hunt will be during a special trad season or just bowhunting in general (including compounds).
IMO, battery-operated accessories have no place in a special traditional hunting season or areas restricted to primitive hunting equipment. It has nothing to do with being ridiculous or unethical and everything to do with honoring the premise under which special allowances for traditional/primitive weapons are established.
Regardless of whether good tracking skills or battery-powered sights/arrows are used, recovering the animal is always the hunter's responsibility.
