  "textContent": "A multi-battery charging and discharging device including a power management integrated circuit (PMIC) module, at least two rechargeable batteries, and a plurality of first field-effect transistors. Each rechargeable battery is connected to a pulse width modulation (PWM) power module of the PMIC module through a field-effect switching transistor, terminals for connecting field-effect switching transistors and the PWM power module are separated from each other. Each of the first field-effect transistors is provided in a connection path between each rechargeable battery and a load. The first field-effect transistor is used to control the connection path between the rechargeable battery and the load to be turned on or turned off.",
