Integrated Multi-Protection Circuit: The built-in protection IC monitors 7.4V cell voltage in real time, guarding against overcharge, over-discharge, overcurrent, and short circuits. This prevents catastrophic cell failure during abnormal operating conditions.
Precision Cell Matching: Each lithium-ion cell undergoes capacity grading and internal resistance sorting before assembly into the 2 x 3.7V lithium polymer cells in series configuration. This matching process ensures uniform charge and discharge across all cells, extending pack lifespan and maintaining voltage stability.
Factory-Tested Quality Assurance: Every battery pack completes a full electrical testing cycle at our Dongguan facility, including charge retention verification, protection board trigger validation, and dimensional inspection. Test reports accompany each batch shipment for OEM traceability.
Global Certification Compliance: Manufactured to meet CE, RoHS, UN38.3, and MSDS documentation requirements. These certifications enable duty-free import into EU markets and compliant air freight for international distribution channels.
Wide Operating Temperature Range: Designed for Charging: 0°C ~ +45°C / Discharging: -20°C ~ +60°C, the pack maintains stable performance across diverse environmental conditions. Cold-weather and high-temperature variants are available through OEM customization.
Stable Voltage Platform: The 7.4V nominal voltage platform delivers consistent output throughout the discharge cycle. This stability is critical for waist-mounted fans requiring uninterrupted power delivery.
Efficient Power Delivery: The discharge curve supports sustained current draw suitable for continuous device operation, with burst capability for startup surges.

Primary deployment scenarios include waist-mounted fans, where the 7.4V 2000mAh (0.2C discharge) capacity supports extended operation between charges. The pack also serves personal cooling devices requiring compact power integration with safety-certified construction. Distributors supplying wearable fans can leverage this pack's CE and UN38.3 compliance for streamlined customs clearance and retail channel entry.
A: Each battery pack ships with CE, RoHS, UN38.3, and MSDS documentation. UN38.3 test summaries cover altitude, thermal, vibration, and impact testing required for air freight compliance. Material safety data sheets are available in English for customs and regulatory submission.
A: Store packs at -20°C ~ +45°C (recommended to store at half charge). Maintain charge level between 30-50% for long-term storage. Perform a maintenance charge every 6 months to prevent deep discharge degradation. Avoid storing in direct sunlight or high-humidity environments.
A: MOQ is flexible based on cell availability and customization requirements. Standard configurations ship within 7-15 business days. Custom OEM orders with modified wire lengths, connectors, or protection parameters require 15-25 business days including prototype sampling. Contact our sales team for a detailed quotation.
A: Yes. Wire length, gauge, and terminal connector model can be modified to match your device PCB interface. Common customizations include Molex, JST, and custom pin configurations. Provide your connector specification and required wire length for DFM review and quotation.
A: Lithium-ion battery packs must not be disposed of in standard waste streams. Follow local e-waste regulations and battery recycling programs. The pack contains recoverable lithium, copper, and aluminum materials. APTPES can provide end-of-life handling guidance for volume customers.
