4S 14.8V 10A SMB Intelligent Li-ion BMS Protection Board for Smart Device Power Tool



ITL0040150037-01 4-Series (4S) SMB Intelligent Lithium Battery Protection Board (Max. Discharge Current 10A) The ITL0040150037-01 is a cutting-edge intelligent protection board designed exclusively for 4-cell series (4S) lithium battery packs—supporting Li-ion, Li-polymer, and LiFePO4 chemistries—with a maximum discharge current of 10A and integrated **SMB (System Management Bus) smart functionality**. Tailored for medium-voltage (nominal 14.8V for Li-ion) and smart-enabled applications, it combines robust battery safety with real-time data monitoring and communication, making it ideal for devices requiring precise battery management, such as industrial IoT sensors, smart portable tools, and medical auxiliary equipment.

4S-Specific Protection & 10A Current Reliability

Calibrated to address the unique needs of 4-cell configurations, the board delivers targeted safeguards optimized for 4S voltage dynamics and 10A medium-power demands:
  • Overcharge Protection: Triggers at 4.25V (Li-ion) per cell (total 17.0V for 4S packs), instantly cutting charging current to prevent cell swelling or thermal runaway—critical for 4S systems where voltage imbalance across four cells accelerates degradation.
  • Undervoltage Protection: Shuts down discharge at 2.5V (Li-ion)) per cell (total 10.0V for 4S packs), avoiding irreversible capacity loss from "weak cells" that compromise stability during 10A operation (e.g., smart tool startup).
  • 10A Overcurrent & Short-Circuit Protection: Blocks currents exceeding 10A (max discharge) or 30A (peak surge), shielding the 4S pack and connected smart devices from burnout.
  • 4-Cell Active Balancing: Automatically equalizes voltage across all four cells during charging, extending battery lifespan by up to 30% vs. unbalanced systems and maintaining consistent 10A discharge performance.

  • SMB Intelligent Core Features

    The integrated SMB bus sets this board apart by enabling seamless communication and smart battery management:
    • Real-Time Data Monitoring: Transmits key battery metrics (cell voltage, total current, temperature, and state of charge/SOC) to a host device (e.g., MCU, smart controller) via the SMB bus, allowing users to track battery health in real time.
    • Remote Fault Diagnostics: Detects anomalies (e.g., overheating, cell imbalance) and sends fault signals through SMB, enabling proactive maintenance instead of reactive repairs—ideal for industrial or medical devices where downtime is costly.
    • Adaptive Charging Optimization: Works with SMB-compatible chargers to adjust charging current based on real-time battery data, preventing overcharging and reducing charging time by up to 15% while preserving cell health.
