Key Features
  • Slim and Lightweight: Compact 8×34×50mm dimensions and 15g weight enable easy integration into small or flat devices.
  • High Performance: NCM/NCA ternary cathode provides energy density of 160-180 Wh/kg.
  • Extended Runtime: 1500mAh capacity supports 6-10 hours continuous use in small devices.
  • Universal Compatibility: 3.7V standard voltage works with most small electronic device power systems.
  • Enhanced Safety: Built-in protection against overcharge, over-discharge, and short circuits.
  • Long Service Life: 500-800 cycles at 0.5C charge/discharge with ≤3% monthly self-discharge.
  • Flexible Installation: Soft-pack design conforms to irregular device structures with optional pre-installed circuit boards.

Main functions of PCM board:


Overcharge protection:


When the battery voltage exceeds the safe upper limit (e.g., 4.25V to 4.3V for a single cell), the protection board quickly cuts off the charging circuit to prevent electrolyte decomposition, gas generation, or thermal runaway, avoiding the risk of fire or explosion.


Over-discharge protection:


During discharge, if the voltage drops below a preset lower limit (typically 2.5V to 3.0V), the protection board immediately disconnects the discharge path to prevent damage to electrode materials or a sudden drop in battery capacity.


Overcurrent and short-circuit protection:


By monitoring the circuit current, when the current exceeds a set threshold , the protection board shuts off the MOS switch within milliseconds, cutting off the circuit; short-circuit protection, for extreme overcurrent conditions, has an even faster response time (microseconds) to prevent high temperatures or damage caused by instantaneous high current. Temperature Protection: 


Integrated with NTC thermistors and other sensors, it monitors battery temperature in real time. If the temperature exceeds 60°C to 70°C during charging, exceeds 80°C during discharging, or the temperature drops below 0°C during charging, the protection board will automatically block charging and discharging to prevent high-temperature decomposition or lithium dendrite formation.


Balancing Function (Suitable for multi-cell series battery packs):


Through passive or active balancing circuitry, it adjusts the voltage differences between individual cells to ensure cell consistency, improving overall capacity and lifespan.
