Protection Circuit Module (PCM) Features

Overcharge Protection

Automatically cuts off charging circuit when voltage exceeds safe limits (4.25V-4.3V) to prevent electrolyte decomposition and thermal risks.

Over-discharge Protection

Disconnects discharge path when voltage drops below preset limits (2.5V-3.0V) to protect electrode materials and maintain capacity.

Overcurrent & Short-circuit Protection

Monitors circuit current and cuts off within milliseconds for overcurrent conditions, microseconds for short-circuit events.

Temperature Protection

Integrated NTC thermistors monitor battery temperature, blocking charging/discharging outside safe ranges to prevent damage.

Balancing Function

Maintains voltage consistency between cells in multi-cell packs, optimizing overall capacity and lifespan.

Applications

Smart Wearable Devices (bracelets, watches, fitness trackers)
Bluetooth Wireless Devices (TWS earphone cases, speakers, receivers)
Portable Detection Instruments (thermometers, detectors, multimeters)
Smart Home Accessories (door lock backup, wireless doorbells, sensors)
Mini Flashlights & Emergency Power Banks
Portable Voice Recorders & Translator Pens
