High-Performance NCM 18650 Battery Cell for Automated Shade & Blind Motors

In the competitive smart home and architectural shading market, motor manufacturers require power sources that offer longevity, reliability, and design flexibility. Traditional Ni-MH batteries limit your product’s potential with short lifespans and bulky form factors.

Goldencell provides advanced NCM 18650-2600mAh cylindrical cells engineered specifically for the rigorous demands of tubular and shade motors. With a verified energy density of 546.22Wh/L, ≥1500 cycles, and extreme -40℃~65℃ operational capability, our cells serve as the ideal foundation for your high-end, WireFree™ shading solutions.

High-Performance NCM 18650 Cells for Automated Shade & Blind Motors

Ultra-Long Cycle Life: 1500 Cycles @ 80% DOD

Our JGCNR18650-2600mAh cells are tested to deliver ≥1500 cycles under 0.5C charge/discharge conditions at 80% Depth of Discharge. This ensures your motor designs achieve a service life of 10+ years under normal usage, significantly enhancing your brand’s reputation for durability and reducing warranty risks.

Extreme Temperature Performance: -40℃ to 65℃

Whether for skylights in cold climates or sun-exposed façades, our cells maintain stability. Proprietary electrolyte technology allows the cells to retain high capacity at low temperature, ensuring reliable motor startup in extreme cold, while remaining structurally safe up to 65℃.

Certified Cell Reliability

The core JGCNR18650-2600mAh cell is certified to UL1642 and IEC62133-2 standards. We provide full technical documentation to support your battery pack assembly and system-level certifications, ensuring compliance and safety from the cell level up.

Minimal Self-Discharge: less than 3% Monthly

Designed for applications with long standby periods, our cells exhibit an extremely low self-discharge rate of < 3% per month. This guarantees that your customers’ shades will function immediately upon installation or after extended periods of inactivity, eliminating the “dead battery” complaints common with Ni-MH alternatives.

High Energy Density: 546.22Wh/L

With an energy density of 546.22Wh/L, our 18650 cells provide maximum power in a minimal footprint. This allows your engineering team to design slimmer Ø35mm/Ø45mm tubular motors or compact external battery wands without compromising runtime.

Flexible OEM/ODM Customization

We sell finished consumer packs&battery cell. We offer custom voltage configurations (2S, 3S, 3S2P, etc.) and work with your engineering team to develop custom PCM/BMS solutions and connector interfaces tailored precisely to your motor’s specifications.

Frequently Asked Questions (FAQ)

Q1: Do you sell finished battery packs with connectors?

A: Yes. We specialize in supplying high-quality 18650 cells to B-end motor manufacturers. We support OEM/ODM customization for battery packs, and the final pack design—including connectors, PCM/BMS, and housing—is tailored to your specific requirements.

Q2: Are your battery packs certified?

A: The individual cells are certified to UL1642 and IEC62133-2. The final assembled battery pack requires certification based on your specific application and design. We provide all necessary cell-level test reports and data to support your certification process.

Q3: Can these cells handle the high current required for motor startup?

A: Yes. Our NCM chemistry is optimized for high-discharge rates suitable for motor loads. We recommend discussing your specific motor startup current (stall current) with our engineers to ensure optimal pack configuration.

Q4: What is your MOQ for custom battery packs?

A: MOQs vary depending on the complexity of the pack design and PCM requirements. Please contact our sales team with your specifications for a detailed quotation and lead time.

Q5: Do you support integration with existing Somfy® or PowerView® ecosystems?

A: Yes. We can engineer custom battery packs using our cells to match the voltage and communication protocols required by your target ecosystem, serving as a high-performance alternative to standard battery solutions.
