Protection Circuit Module Functions
Overcharge Protection: Cuts off charging circuit at 4.2V-4.25V to prevent cell damage, fire, or explosion
Over-Discharge Protection: Disconnects discharge circuit at 2.5V-2.3V to prevent permanent capacity loss
Overcurrent Protection: Monitors charging/discharging current and shuts down if exceeding safe thresholds (e.g., 3A)
Short Circuit Protection: Rapid circuit cutoff within milliseconds during short circuit events
Temperature Protection: NTC thermistors limit operation in extreme temperature conditions (>60℃)
Battery Balancing: Advanced models ensure consistent voltage across multi-cell configurations
