1. A battery module, for use in a battery system which is configured to be operable in a bottom mode or a top mode during an enabled state, the battery module comprising:
a battery unit, including at least one battery, wherein the battery unit generates a battery unit voltage between a positive terminal and a negative terminal of the battery unit; and
a battery control circuit, powered by the battery unit voltage and configured to operably detect the battery unit voltage and/or to control the battery unit, wherein the battery control circuit includes an enable terminal, an upstream input terminal, an upstream output terminal, a downstream input terminal, and a downstream output terminal;
wherein when the upstream input terminal is at an upstream enabling level, the battery module enters the enabled state.
