Single battery life is configured with only one battery, and dual battery life will be configured with another battery in addition to a battery inside the drone, so that when one battery is used, another battery can be charged to extend the battery life. Therefore, the dual battery life is to provide two batteries, which can be used alternately, and the dual battery means that in order to continuously maximize the use of batteries, the power requirements of the aircraft in flight will vary according to your operation.
A drone is equipped with two batteries, which can be charged in advance, and a battery can be replaced with a battery to play.
