Supports a new power collection function, which can transfer the power of multiple batteries to the battery with the highest remaining power; it can expand the charging port of the intelligent flight battery to 3, and fast charge them in order of remaining power from high to low (requires a designated charger), eliminating the hassle of waiting for a long time and plugging and unplugging batteries one by one, and also allowing for quick charging of remote controllers, mobile phones, and other devices.
