High Performance 11S 40V Lithium Battery BMS 15A with Comprehensive Protection

The BAKTH-011S020A-0130-01 is a precision-engineered protection board exclusively designed for 11-cell series (11S) lithium battery packs—covering Li-ion, Li-polymer, and LiFePO4 chemistries—with a maximum discharge current of 15A. Its model code reveals key design cues: “011S” confirms native compatibility with 11-series cells, while “020A” indicates a robust current handling range that aligns with its 15A max discharge rating. Tailored for high-voltage (nominal 40.2V for Li-ion, 35.2V for LiFePO4) and medium-power devices, it balances multi-layered safety with stable performance, making it ideal for electric tools, portable energy storage units, and light mobility gear.
11S-Specific Protection & 15A High-Current Safeguards
Calibrated to address the unique risks of 11-cell packs, the board delivers targeted protection optimized for 11S voltage dynamics and 15A discharge demands:
  • Overcharge Protection: Triggers at 4.25V (Li-ion)/3.65V (LiFePO4) per cell, instantly cutting charging current to prevent thermal runaway—critical for 11S packs where cumulative voltage (up to 46.75V fully charged for Li-ion) amplifies overcharge hazards.
  • Undervoltage Protection: Shuts down discharge at 2.5V (Li-ion)/2.0V (LiFePO4) per cell, avoiding irreversible capacity loss from “weak cells” that can disable the entire 11S system, especially during 15A high-load operation.
  • 15A Overcurrent & Short-Circuit Protection: Blocks currents exceeding 15A (max discharge) or 45A (peak surge), shielding the 11S pack and connected devices (e.g., cordless grinders, small e-scooters) from burnout during startup or heavy use.
  • 11-Cell Active Balancing: Automatically equalizes voltage across all 11 cells during charging, eliminating uneven charge distribution—a major challenge in high-cell-count packs. This extends the 11S pack’s lifespan by up to 35% vs. unbalanced systems and maintains consistent 15A discharge capability.
