Rated at 18.5V nominal voltage and 3200mAh capacity, this APTPES lithium battery pack targets emergency power supplies where space and weight constraints are critical. The lithium-ion cell architecture configured as 5 Series 1 Parallel (5S1P) provides balanced energy density at approximately Approximately 200g (for reference only). A built-in protection IC safeguards against overcharge, over-discharge, and short circuits. Factory-assembled with terminal wires for plug-and-play integration. Contact our engineering team for customization inquiries.
Integrated Multi-Protection Circuit: The built-in protection IC monitors 18.5V 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 5 Series 1 Parallel (5S1P) 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.
Low Self-Discharge Design: Advanced lithium-ion chemistry limits self-discharge to under 3% per month at room temperature. This characteristic supports inventory rotation and device storage without frequent recharge maintenance.
Balanced Thermal Management: Cell spacing and wrapping materials facilitate passive heat dissipation during charge and discharge cycles. The pack design prevents thermal hotspots that accelerate cell degradation, contributing to consistent long-term performance.
Compact Energy Density: Measuring Approximately 38mm * 38mm * 68mm (excluding wires), this pack maximizes energy storage within minimal volume at Approximately 200g (for reference only). The form factor suits embedded installation in device housings with tight spatial budgets.

A: The dimensions (Approximately 38mm * 38mm * 68mm (excluding wires)) refer to the battery cell body only. Flexible connecting wires and terminal connectors add approximately 20-80mm beyond the stated measurements. Account for wire routing space when designing your device's battery compartment.
A: The maximum continuous discharge current is Typically 1C (3.2A), depending on the cell model a. Verify your device's steady-state current draw and startup surge requirements against these ratings. If your application needs higher current, we can customize the cell selection and protection board parameters.
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 at room temperature (20-25°C) with charge level between 30-50%. Perform maintenance charging every 6 months. Keep in dry, ventilated storage away from direct sunlight.
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.
