Designed for high-performance 10-cell series (10S) lithium battery packs—compatible with Li-ion, Li-polymer, and LiFePO4 chemistries—this protection board delivers a maximum discharge current of 30A, making it a powerful solution for medium-to-high power, high-voltage applications (nominal 37V for Li-ion, 32V for LiFePO4). Engineered to balance robust safety controls with responsive high-current handling, it is ideal for electric mobility gear, heavy-duty power tools, and mid-scale energy storage systems that demand reliable protection for 10S battery configurations.
10S-Specific Protection & 30A High-Current Safeguards
Calibrated to address the unique dynamics of 10-cell packs, the board provides targeted protection optimized for 10S voltage profiles and 30A discharge demands:
Overcharge Protection: Triggers at 4.25V (Li-ion) per cell (total 42.5V for 10S packs), instantly cutting charging current to prevent cell swelling, electrolyte breakdown, or thermal runaway—critical for 10S systems where voltage imbalance across 10 cells amplifies degradation risks.
Undervoltage Protection: Shuts down discharge at 2.5V (Li-ion) per cell (total 25V for 10S packs), avoiding irreversible capacity loss from "weak cells" that compromise stability during 30A high-load operation (e.g., electric scooter acceleration or power tool startup).
30A Overcurrent & Short-Circuit Protection: Blocks currents exceeding 30A (max discharge) or 90A (peak surge), shielding the 10S pack and connected devices from burnout during sustained high-power use or accidental short circuits.
10-Cell Active Balancing: Automatically equalizes voltage across all 10 cells during charging, eliminating uneven charge distribution—a major challenge in high-cell-count packs. This feature extends battery lifespan by up to 40% compared to unbalanced systems and maintains consistent 30A discharge performance.
