    Abstract: A battery device and a battery management method are provided. The battery device includes two battery packs and a management module that can obtain a piece of battery health data for each of the two battery packs. When the management module detects that a first variation between two pieces of the battery health data is greater than 2%, the management module selects one of the two battery packs in which the battery health data is high to supply power to an electric bicycle, and another one of the two battery packs in which the battery health data is low to suspend operation. When the management module detects that the first variation between the two pieces of the battery health data is less than 2%, the management module selects one of the battery packs to supply power to the electric bicycle according to a first rule.
