Powering patient monitors demands a battery pack that balances capacity, safety, and form factor. APTPES engineered this 11.1V 3200mAh (0.2C discharge) lithium-ion battery pack to meet those requirements, featuring integrated overcharge and short-circuit protection, factory-tested cell matching, and ready-to-use wire terminals. With 3 Series 1 Parallel (3S1P) 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 11.1V 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 3 Series 1 Parallel (3S1P) 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 11.1V nominal voltage platform delivers consistent output throughout the discharge cycle with sustained current capacity up to 1C (approximately 3.2A), specific detail. This stability is critical for patient monitors requiring uninterrupted power delivery.
Efficient Power Delivery: Maximum continuous discharge at 1C (approximately 3.2A), specific details refer to supports devices with variable load profiles and startup surge requirements.
