OEM Customization 5S 18V Li-ion BMS Protection Board for Industrial Equipment


  • The BAKTH-005S010A-0138-01 is a model-specific 5S lithium battery protection board, engineered to safeguard 5-cell series (5S) lithium battery packs—with tailored safety and performance optimization. Designed for mid-to-high voltage applications, this board acts as a critical safeguard against battery damage and safety hazards, while its “010A” designation indicates a 10A continuous current rating, making it ideal for power-demanding devices like electric tools, portable energy storage units, and light mobility gear.
  • ​
    5S-Specific Protection & Precision​
    Optimized for 5S battery configurations, the BAKTH-005S010A-0138-01 delivers calibrated safeguards for 5 individual cells:​
    • Overcharge Protection: Triggers when any cell exceeds 3.75V (Li-ion), cutting off charging current to prevent cell swelling, electrolyte breakdown, or thermal runaway—critical for 5S packs where voltage accumulation amplifies overcharge risks.​
    • Undervoltage Protection: Shuts down discharge if a cell drops below 2.2V (Li-ion), avoiding irreversible capacity loss that often plagues multi-cell packs due to “weak cell” drag. ​
    • Overcurrent & Short-Circuit Protection: Instantly blocks currents exceeding 10A (continuous), shielding the 5S pack and connected devices from burnout during high-load operation (e.g., electric drill startups) or accidental short circuits.​
    • 5-Cell Balancing: Automatically equalizes voltage across all 5 cells during charging, eliminating uneven charge distribution and ensuring each cell operates at peak efficiency—extending the 5S pack’s overall lifespan by up to 30% compared to unbalanced systems.
    • ​
    Technical Advantages for Reliability​
    Equipped with high-precision voltage detection chips (±2mV accuracy), the board monitors each cell’s status in real time, ensuring timely and consistent protection responses. Its ultra-low static current (<10μA) minimizes idle power drain, keeping the 5S pack ready for use during storage. The board also features auto-recovery: once fault conditions are resolved, it resumes normal operation without manual reset, enhancing user convenience for industrial or daily-use devices.
