    The 3S Lithium Battery Protection Board is a critical safety and performance component engineered exclusively for 3-cell series (3S) lithium battery packs, including Li-ion, Li-polymer, and LiFePO4 configurations. Designed to prevent battery damage and mitigate safety risks, this board acts as a “guardian” for 3S battery systems, ensuring stable operation and extending the lifespan of connected battery packs—making it essential for consumer electronics, industrial devices, and portable power solutions.

    Core Protection Functions for 3S Battery Packs
    Tailored to 3S battery packs (typical nominal voltage: 11.1V for Li-ion, this board delivers multi-layered safeguards:
    • Overcharge Protection: Triggers when any cell voltage exceeds 4.25V (Li-ion), cutting off charging current to avoid cell swelling or thermal runaway.
    • Undervoltage Protection: Shuts down discharge when a cell drops below 2.5V (Li-ion), preventing irreversible battery capacity loss.
    • Overcurrent & Short-Circuit Protection: Instantly blocks high currents caused by short circuits or overloads (e.g., faulty devices), protecting both the battery and connected equipment.
    • Cell Balancing: Automatically equalizes voltage across the 3 cells during charging, ensuring each cell charges uniformly—eliminating “weak cell” issues that reduce overall battery capacity and lifespan.

    Versatile Application Scenarios
    Ideal for any 3S lithium battery-powered device, including:
    • Consumer electronics: 3S drone batteries, portable power banks, and high-power LED flashlights;
    • Industrial equipment: 3S electric tools (e.g., cordless drills), IoT sensor batteries, and small medical devices;
    • Recreational gear: 3S e-scooter auxiliary batteries, camping lanterns, and RC toy power packs.
