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
Applications
  • Bluetooth Speakers and Headphones
  • Handheld Game Consoles and VR Accessories
  • Action Cameras and Drones
  • Bluetooth Earphones and Charging Cases
  • Dash Cams and Continuous Recording Devices
  • Portable Speakers, Walkie-Talkies, and Audio Devices
  • Power Banks, Locators, and Humidifiers
  • Smart Bracelets, Night Lights, and Beauty Devices
  • DIY Electronics Projects and Equipment Upgrades
