Integrated Multi-Protection Circuit: The built-in protection IC monitors 14.8V 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 4 Series 2 Parallel (4S2P) 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.
OEM Customization Support: Wire length, terminal connector model, cell capacity, and protection board parameters can be modified to match proprietary hardware specifications. Our engineering team provides DFM review and prototype sampling within 7-10 business days.
Rigorous Safety Standards: Manufactured under ISO-compliant processes with full material traceability. The lithium-ion cells meet UN38.3 transportation testing requirements including altitude simulation, thermal cycling, vibration, and impact testing.
Optimized for Volume Production: Tiered pricing structures reward volume procurement with flexible MOQ arrangements. Standardized lithium-ion cell sourcing and automated assembly lines ensure consistent lead times for recurring production orders.

Targeted at cordless household appliances applications, this battery pack addresses the power requirements of kitchen tools and home cleaning devices. The 14.8V nominal voltage matches standard device input specifications in these categories, eliminating the need for voltage regulation circuitry in compatible designs. Procurement teams sourcing for cordless household appliances programs can request application-specific test data from our engineering department.
A: Standard warranty covers manufacturing defects for 12 months from shipment date. This includes cell capacity degradation below 80% of rated capacity under normal use conditions. Warranty does not cover damage from improper charging, physical impact, or operation outside specified temperature ranges.
A: Yes. All packs are UN38.3 certified and shipped with proper dangerous goods documentation (IATA/IMDG compliant). Packs are packaged in UN-rated boxes with insulation and short-circuit protection. Our logistics team handles DG declaration paperwork for international air and sea freight.
A: Use a dedicated lithium-ion charger with 16.8V ± 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.
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 to prevent cell damage from short circuits.
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.
