Train security screening is permitted, but aircraft security screening is not.
According to the "Regulations on Passenger Rail Transportation", the items prohibited on trains include items prohibited or restricted for transportation by the state, dangerous goods specified in laws and regulations, ammunition , etc. ; lithium batteries. Therefore, 48-volt lithium batteries can pass train safety inspection;
Items prohibited on aircraft include toxic and corrosive chemicals, flammable materials, etc. ; The electrolyte in lithium batteries is strong acid and lithium. Batteries easily contain flammable materials, so 48-volt lithium batteries cannot pass aircraft safety inspection.

BanksPower banks can be taken on board the aircraft, but power banks exceeding 20,000 mAh cannot be taken on board.
The Civil Aviation Administration of China has regulations that you can take power banks on board an aircraft, but there are some restrictions on the number and energy of power banks and on their transport. In special circumstances you need permission. of the Civil Aviation Administration before being able to transport them.
Regulations of the Civil Aviation Administration of China regarding the transportation of external batteries
1. Those with a rated energy of less than 100Wh can be carried on board the aircraft
The Civil Aviation Administration of China has issued regulations for carrying mobile power banks on board planes. According to current regulations, batteries eExternal batteries with a nominal energy of less than 100 Wh can be taken on board an aircraft. 160Wh can only be boarded with the agreement of the airline. The power bank will not directly indicate the rated energy, only the capacity. Therefore, only through conversion can we know what capacity of the external battery can be carried on board the aircraft.
2. Formula conversion
Taking a 37V/10000mAh power bank as an example, the rated energy = 3.7V times 10000mAh = 37Wh, which is less than 100 Wh. regulations and can be taken on board the aircraft. Similarly, the maximum output voltage of a general external battery is 5V. According to the formula, capacity = rated energy divided by 100Wh divided by 5V is equal to 20,000 mA. can be taken on board a plane.
3. Quantity rules
Each passenger can carry up to 2 power banksn the aircraft, and the rated energy cannot exceed 100 Wh, that is, the total capacity does not exceed 20,000 mAh. . Therefore, a 20,000 mAh external battery cannot be taken on a plane.
72v50a lithium battery can pass safety inspection. Dry batteries are allowed on trains. As long as the weight and volume of lithium batteries do not exceed the above regulations, you can bring them. Lithium batteries can be taken on trains, with no limit on their number. Lithium batteries are not prohibited items and can be carried on trains. Simply drop off your luggage at the station and go through security. Each lithium-ion battery must be packed in a container to ensure that the positive and negative terminals of the battery will not short circuit. It is best to pack it in its original packaging orwrap the electrodes with adhesive tape.
Things to note when going through security
Please do not attempt to pass checked baggage or carry-on baggageAll items including transportation or check-in is prohibited are included in your baggage and personal effects. If you are traveling with “excess three” (oversized, excessive or overweight) items, please consult the appropriate department for your flight in advance. When inspecting documents, please prepare tickets and valid documents in advance (they must be consistent with the documents used when booking tickets) and actively submit them to the document inspector for inspection.
