Integrated Multi-Protection Circuit: The built-in protection IC monitors 14.8V 3.7V per cell * 4 cells 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 into the 4 Series 1 Parallel (4S1P) 4 cells in series, voltage added; no parallel connection, capacity remains unchanged 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: Operates reliably from -20°C to +60°C for discharge and 0°C to +45°C for charging, supporting deployment in varied climate conditions.
Stable Voltage Platform: The 14.8V 3.7V per cell * 4 cells nominal voltage platform delivers consistent output throughout the discharge cycle with sustained current capacity up to Typically 4A - 6.4A Depends on the cell. This stability is critical for robotic vacuum cleaners requiring uninterrupted power delivery.
Efficient Power Delivery: Maximum continuous discharge at Typically 4A - 6.4A Depends on the cell's C-rate supports devices with variable load profiles and startup surge requirements.
