Powering storytelling devices demands a battery pack that balances capacity, safety, and form factor. APTPES engineered this 3.7V 3200mAh (under standard test conditions) 18650 cylindrical battery pack to meet those requirements, featuring integrated overcharge and short-circuit protection, factory-tested cell matching, and ready-to-use wire terminals. With configuration and proven cycle life exceeding 500 charges, it is built for volume procurement and OEM integration. Request a quote for your project specifications.
Integrated Multi-Protection Circuit: The built-in protection IC monitors 3.7V 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 18650 cylindrical cell undergoes capacity grading and internal resistance sorting before assembly. 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 (recommen, the pack maintains stable performance across diverse environmental conditions. Cold-weather and high-temperature variants are available through OEM customization.
Stable Voltage Platform: The 3.7V nominal voltage platform delivers consistent output throughout the discharge cycle with sustained current capacity up to Typically 1C (3200mA), depending on the . This stability is critical for storytelling devices requiring uninterrupted power delivery.
Efficient Power Delivery: Maximum continuous discharge at Typically 1C (3200mA), depending on the cell's rat supports devices with variable load profiles and startup surge requirements.
