The U.S. Federal Aviation Administration has adjusted the list of items that are forbidden to carry on passenger flights. So, with luggage, you can no longer hand over lithium-ion batteries. True, you can still take your devices to the cabin. Transportation of lithium-ion batteries in the luggage compartment is now allowed only on cargo flights. However, the changes affected this moment. Battery charging should not exceed 30 percent. This should reduce the risk of fire. The fact is that such incidents on board the aircraft are fraught with very serious consequences. If the battery ignites in the cabin, passengers or cabin crew will be able to quickly detect a source of ignition. In addition, the salon is equipped with fire extinguishers. Fire extinguishing systems are also available in luggage compartments. However, as practice shows, they are not so effective. It is likely that changing requirements may delay the supply of batteries. People will be forced to wait for cargo liners. Until now, batteries could also be sent by passenger flights.
