6S 22.2V Overcharge/Short Circuit Protection lithium Battery Protection Board BMS for Li-ion Packs

6S 22.2V Overcharge/Short Circuit Protection lithium Battery Protection Board BMS for Li-ion Packs

• 

• The BAKTH-006S006A-0115-01 is a precision-engineered 6S lithium battery protection board, exclusively designed to safeguard 6-cell series (6S) lithium battery packs. Its model designation reveals key performance traits: “006S” denotes compatibility with 6-series cells, while “006A” indicates a 6A continuous current rating, making it ideal for medium-voltage, moderate-power devices that demand stable protection without compromising efficiency.

  
  

  6S-Tailored Protection & Calibrated Safety

  Optimized for 6S battery configurations (nominal voltage: 22.2V for Li-ion), this board delivers multi-layered safeguards calibrated to 6 individual cells:

  
  

  • Overcharge Protection: Triggers when any cell exceeds 4.25V (Li-ion), instantly cutting off charging current to prevent cell swelling, electrolyte leakage, or thermal runaway—critical for 6S packs where cumulative voltage amplifies overcharge risks.

  • Undervoltage Protection: Shuts down discharge if a cell drops below 2.75V (Li-ion), avoiding permanent capacity loss caused by “weak cells” that can disable entire 6S systems.

  • Overcurrent & Short-Circuit Protection: Blocks currents exceeding 6A (continuous) or 18A (peak), shielding the 6S pack and connected devices from burnout during high-load operation (e.g., small electric tool startups) or accidental short circuits.

  • 6-Cell Balancing: Automatically equalizes voltage across all 6 cells during charging, eliminating uneven charge distribution—a common issue in multi-cell packs—and ensuring each cell operates at peak efficiency, extending the 6S pack’s lifespan by up to 30%.
