Important:
Europe, Japan, the United States and other regions suggest choosing the seller's logistics method. Usually, the seller's logistics method can ship the aircraft and all batteries in one package.

AliExpress standard logistics cannot carry multi battery versions.
Usually, a package is shipped with a built-in battery and its accessories on the aircraft.
The second and third spare batteries are shipped separately in one package.
In some cases, if air transportation is restricted, all batteries are shipped separately in one package. Ship one package with aircraft (excluding batteries) and accessories.
Brazil suggests not buying dual/triple electric versions.
