Core Product Strengths

1. Real Standard Capacity Without False Labeling
Every single 18650 cell passes strict capacity sorting before assembly. The actual energy 16.28Wh matches the labeled parameter perfectly, avoiding endurance attenuation and customer complaints for finished equipment.

2. Stable Long-Time Continuous Discharge
Ultra-low internal resistance design ensures smooth voltage output during long-hour working, ideal for low & medium power devices like heating vests and portable fragrance machines, without sudden power drop or unstable operation.

3. Multi-Layer Built-In Safety Design
The integrated protection circuit effectively blocks short-circuit, overheating and abnormal charging risks. The outer blue heat-shrink tube provides anti-extrusion and insulation performance, safe for daily wearable & indoor equipment use.

4. Standard Compliance for Global Export
The battery label is printed with mandatory WEEE waste battery recycling symbol, fully complying with EU electronic waste regulations. Complete UN38.3, CE, RoHS documents are provided for air & sea customs clearance in Europe, Southeast Asia, India and other regions.

5. Flexible Customization for B-End Clients
We support customized wire length, JST/Molex terminals, custom LOGO silk printing on battery surface, neutral carton packaging and dedicated PACK structural adjustment according to your finished product internal space demands. Small batch sampling and mass stable production are both acceptable.

Wide Application Scenarios

• Electric heating vest / heating jacket wearable thermal devices

• Wireless lavalier microphones & teaching voice amplifiers

• Portable aroma diffusers, mini car humidifiers

• Outdoor human body sensing lamps, mini monitoring cameras

• Other 7.4V low-power portable consumer electronics
