How to make sure the quality?
1. A-grade battery cell:
Using lithium battery raw materials from major industry brands, they have sufficient capacity, low internal resistance, long battery life, no inflation, and are manufactured using fully automated processes.
2. High-performance protection board:
Adopt high-strength protection board, stable voltage output, with charge and discharge overcurrent protection, short circuit protection and temperature protection, to prevent overcharge and overcurrent from damaging the battery.
3. High-quality silicone cable:
Using high-quality environmentally friendly wire, it is flexible and not easy to break. Different models of wires can be selected according to customer needs to meet different power discharges and prevent safety accidents.
Application:
MP3/MP4 player: As a mainstream portable device battery, it provides long-term battery life support.
GPS tracker: Used for outdoor positioning equipment, requiring stable power supply performance.
Bluetooth headset/speaker: Adapt to wireless devices, emphasizing lightweight and long battery life.
Storage precautions for lithium polymer batteries:
Temperature and humidity: The ideal storage temperature is 15-25℃. Avoid high temperature (＞35℃) or humid environment. High temperature will accelerate battery aging, and humidity may cause short circuit or corrosion.
Power management: It is recommended to keep the power at 50% for long-term storage, and avoid full charge or over discharge. Regular charge and discharge cycles can maintain battery health.
Isolation and protection: Keep away from fire and flammable materials. Use fireproof containers or fireproof bags when storing, and ensure good ventilation.
