...or... go around?

Except you started with 1500 miles of charge for a 200 mile flight because "fully charged" weighs less.

If you're up there waiting for a long time you don't have to fly in a tight circle at a high speed.

The issue is maximum take off weight. Presumably the discharged battery weight would be the one you use in the pre-flight MTOW calculations, because the worse case scenario is one where you're landing an almost discharged battery and have to go around.
