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.
