Before leaving home
- Check every battery for swelling, dents, punctures, heat damage or recall status.
- Confirm the Wh rating printed by the manufacturer.
- Protect each spare battery's terminals individually.
- Put spare/removed lithium batteries in your cabin baggage, not checked baggage.
- Completely switch off the drone if the aircraft itself is checked.
- Open your airline's official rule page one final time.
Terminal protection
Use original retail packaging, a battery case/sleeve, a snug individual plastic bag, or non-conductive tape over exposed terminals. A charging hub by itself should not be assumed to be short-circuit protection.
At the gate
If staff take your cabin bag for gate checking, remove all spare lithium batteries first and keep them in the cabin.
Do not travel with a damaged or swollen pack. This is not a borderline packing question; damaged batteries can be a serious fire hazard.
