Flying on an airliner with spare drone batteries, where must the spares go?

In carry-on baggage only, with the terminals protected.

  1. In carry-on baggage only ✔
  2. In checked baggage
  3. Shipped separately as air cargo

Why: Spare lithium batteries must stay in the cabin, where a problem can be spotted and handled. Cover the terminals or use a case so they can't short circuit.

Huh, didn't know that: Lithium ion batteries are capped at 100 watt-hours each, though airlines may approve up to two spares of 101 to 160 Wh.

The dad joke
Why did the spare battery sit in the cabin? It wanted to be a positive influence.
