Product Description
7S 24V BAKTH-010S020A-0135-01 Li-ion BMS Protection Board for E-Bike Power Tool
The BAKTH-010S020A-0135-01 is a specialized 7S lithium battery protection board, engineered to safeguard 7-cell series (7S) lithium battery packs—covering Li-ion, Li-polymer, and LiFePO4 chemistries—with tailored safety and performance. While its model code includes “010S” (indicating broad design compatibility), it is optimized for 7S configurations. This makes it ideal for medium-to-high voltage (nominal 25.2V for Li-ion, 22.4V for LiFePO4) devices that demand reliable protection and stable power delivery.
7S-Specific Protection for Multi-Cell Safety
Calibrated exclusively for 7S battery packs, the board addresses the unique risks of 7-series cells with targeted safeguards:
- Overcharge Protection: Triggers when any cell exceeds 4.25V (Li-ion) or 3.65V (LiFePO4), instantly cutting off charging current to prevent cell swelling, electrolyte breakdown, or thermal runaway—critical for 7S packs where cumulative voltage amplifies overcharge hazards.
- Undervoltage Protection: Shuts down discharge if a cell drops below 2.5V (Li-ion) or 2.0V (LiFePO4), avoiding irreversible capacity loss caused by “weak cells” that can disable the entire 7S system.
- Overcurrent & Short-Circuit Protection: Blocks currents exceeding 20A, shielding the 7S pack and connected devices from burnout during high-load operation (e.g., electric tool startups) or accidental short circuits.
- 7-Cell Balancing: Automatically equalizes voltage across all 7 cells during charging, eliminating uneven charge distribution—a common issue in multi-cell packs—and ensuring each cell operates at peak efficiency, extending the 7S pack’s lifespan by up to 35%.
