Technical Specifications & Performance Advantages
The 26650 cylindrical cell format (26mm diameter × 65mm length) offers superior energy density compared to traditional 18650 cells. CNS BATTERY’s 26650 cells feature:
- Capacity Range: 4000mAh to 5500mAh depending on chemistry configuration
- Voltage Platform: 3.2V (LiFePO4) or 3.7V (NMC/NCA)
- Cycle Life: 2000+ cycles at 80% DOD for LiFePO4 variants
- Operating Temperature: -20°C to 60°C with optimized thermal management
- Internal Resistance: ≤35mΩ ensuring efficient power delivery
These specifications result from advanced electrode coating technology, precision winding processes, and rigorous quality control protocols implemented throughout the manufacturing chain.
Testing Methodologies & Quality Assurance
CNS BATTERY employs comprehensive testing protocols aligned with international standards:
Electrical Performance Testing: Capacity verification, internal resistance measurement, and rate capability assessment using Arbin BT2000 cyclers. Each batch undergoes 100% electrical screening before shipment.
Safety Validation: Cells pass UN38.3, IEC62133, and UL1642 certifications. Abuse testing includes overcharge, short circuit, crush, and thermal runaway scenarios.
Environmental Compliance: RoHS, REACH, and CE marking ensure compatibility with European market requirements. For North American deployments, UL and FCC certifications are available upon request.
Long-term Reliability: Accelerated aging tests simulate 5+ years of field operation, validating cycle life predictions through Arrhenius modeling.
