In some examples, this disclosure describes a method of operating a plurality of battery management circuits of a battery management system associated with an electric device. The method may comprise adjusting a first trim value associated with a first battery management circuit during operation of the electric device, and adjusting a second trim value associated with a second battery management circuit during operation of the electric device. The method may also comprise sinking a first amount of current in the first battery management circuit based on the first trim value; and sinking a second amount of current in the second battery management circuit based on the second trim value, wherein sinking the first amount of current and sinking the second amount of current causes the first battery management circuit and the second battery management circuit to consume substantially similar amounts of current.
