Features & Benefits

• 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 18650 cylindrical cell undergoes capacity grading and internal resistance sorting before assembly into the 2 Series 1 Parallel (2S1P) 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.

• Compact Energy Density: Measuring Φ18mm × 110mm (Diameter × Length, including wire terminals, , this pack maximizes energy storage within minimal volume at Approximately 45g (including protection board and wires). The form factor suits embedded installation in device housings with tight spatial budgets.

• Plug-and-Play Terminal Integration: Pre-configured with Standard length approximately 80mm wires with pluggable terminals (spe, the pack eliminates field soldering requirements. Assembly teams can integrate it directly into device PCBs with standard connector mating.

• Extended Cycle Life: The 18650 cylindrical cells exhibit no memory effect and maintain over 80% capacity retention after 500 full charge-discharge cycles. Low self-discharge characteristics (under 3% per month) support long-term storage without significant capacity loss.

Frequently Asked Questions

Q1: What charger is required for this battery pack?

A: Use a dedicated lithium-ion charger with 8.4V (±0.05V) output in CC/CV (constant current/constant voltage) mode. Standard AC/DC adapters without CC/CV regulation will damage the protection IC and risk thermal runaway. Recommended to use a dedicated 7.4V lithium battery charger

Q2: How does the protection board function during operation?

A: The integrated protection IC continuously monitors cell voltage and current flow. It disconnects the circuit when voltage drops below the safe threshold (over-discharge protection) or exceeds the charge limit (overcharge protection). The board also triggers on overcurrent events above ≤2A (limited by protection boa to prevent cell damage from short circuits.

Q3: Can I connect multiple packs in parallel for higher capacity?

A: Direct parallel connection of finished battery packs is not recommended. Even identical models from the same batch may have slight voltage and internal resistance differences that cause circulating currents. For applications requiring higher capacity, contact our engineering team to order factory-balanced multi-parallel packs with matched cells.

Q4: Do the listed dimensions include the wire terminals?

A: The dimensions (Φ18mm × 110mm (Diameter × Length, including wire t) 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.

Q5: Is the discharge current sufficient for my device?

A: The maximum continuous discharge current is 1C (approximately 1000mA) with peak burst capability of ≤2A (limited by protection boa. 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.
