  "textContent": "The present application provides power supply control circuits, power tools, and power tool systems. The power supply control circuit includes: a main control chip module connected to battery packs; control circuits connected in parallel and connected to the main control chip module and provided on a power supply path from the battery pack to a power tool to control connection and disconnection of the battery packs; and a voltage detection circuit connected to the power supply path and the main control chip module. The main control chip module controls the connection and disconnection of the battery packs through the control circuit based on feedback from the voltage detection circuit, and when the voltage detection circuit detects that the voltage of a currently connected battery pack is less than a predetermined value, controls the currently connected battery pack to be disconnected and select the other battery pack to be connected.",
