Nothing you said negates anything in my post. Batteries ARE allowed in check baggage if they are installed in a device. A drone with a battery pack installed it in IS allowed in checked bags, with none of the resturctions you've mentioned other than the maximum capaity restriction.
Batteries NOT installed in devices are NOT allowed in check bags, nor are battery recharging devices (aka power banks/etc).
I've travelled multiple times with laptops in check luggage and never had a problem. I advised the staff at check-in who confirmed it was OK. On one occasion my bag was opened by TSA (I suspect for something other than the laptop, but they would have seen it), and it was allowed to fly.
You can find a copy of the IATA factsheet on this at
