The HX-2S-A2 is a reliable and compact 2S lithium battery protection board designed for 7.4V (2-cell) 18650 battery packs. It features a circular form factor ideal for integrating within cylindrical battery setups. This module ensures safe operation of lithium-ion cells by offering overcharge, over-discharge, short circuit, and overcurrent protection. It is built to handle moderate power loads and is suitable for various low-power electronics projects. Features
  • Round compact design (17.5mm diameter) optimized for cylindrical battery configurations

  • Integrated protection against overcharge, over-discharge, overcurrent, and short circuit

  • Long operational lifespan of over 50,000 hours

  • Short circuit protection with automatic recovery after charging

  • Ultra-low quiescent current consumption

  • High reliability and performance in wide operating temperature conditions

Important Notes

  • This protection module is not suitable for use with:

    • Lithium iron phosphate (LiFePO4) batteries

    • High-drain applications like hernia lamps, hand drills, electric bicycles, fish machines

    • Motors drawing >4A (e.g., 775 motors), or high-power LEDs (e.g., 1W fish-eye LEDs)

  • Batteries must be in good condition—excessive heat indicates the battery is incompatible or defective

  • Do not continue use if the battery heats up during operation to avoid damage or failure

Applications

  • 2-cell 18650 lithium-ion battery packs

  • Portable low-power devices

  • DIY electronics and robotics

  • Low-power LED systems

  • Battery-powered instruments and toys

  • Wearable or compact embedded electronics
