10S 36V 30A High Current Li-ion Battery Protection Board for E-bike Power Tool Industrial Equipment

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.
