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