    Description
    This module connects two 18650 Lithium-ion batteries in series (2S) to provide safety management. It supports a maximum continuous current of 10 Amperes (10A).
    Key Features:
    • Overcharge Protection: Prevents batteries from exceeding safe voltage limits.
    • Over-discharge Protection: Stops batteries from draining below dangerous levels.
    • Overcurrent Protection: Cuts power if current draw exceeds 10A.
    • Short-circuit Protection: Shuts down output instantly during short circuits.

    Specifications:
    • Nominal Voltage: 7.4 Volts (3.7V per cell).
    • Fully Charged Voltage: 8.4 Volts (4.2V per cell).
    • Charging Voltage Range: 8.4V – 9.0V DC.
    • Working Current: Up to 10A continuously.

    Common Wiring Layout:
    • B+: Connects to the positive terminal of the first battery.
    • B-: Connects to the negative terminal of the second battery.
    • BM: Connects to the middle point between the two batteries.
    • P+: Connects to the positive charge input and load output.
    • P-: Connects to the negative charge input and load output.
    Common Applications:
    • Robotics: Powers small robot chassis, Arduino-based vehicles, and robotic arms.
    • Portable Electronics: Powers handheld walkie-talkies, custom Bluetooth speakers, and LED camping lanterns.
    • Backup Power: Acts as a mini-UPS for 5V–12V routers, modems, and security cameras.
    • Power Tools: Drives low-power electric screwdrivers, mini vacuums, and engraving pens.
    • Smart Home Devices: Energizes motorized window blinds, smart door locks, and outdoor sensor arrays.
    • Massagers: Fuels cordless neck massagers, fascia guns, and heating pads.
