RJ TECH Grade A Layered Oxide Sodium Cell 3.0V Prismatic 50Ah to 280Ah Fast Charging 15 Min -40C Cold Start OEM ODM Factory

Features:

• Outstanding Low Temperature -40 °C Performance 

  Excellent Low-termperature performance without preheat delays, heating films, or parasitic power draw—radically simplifying your thermal design and  system costs.

• Super long life >10,000 Deep Cycles

  Delivers 10,000 deep cycles using Grade A prismatic cells—outlasting lead-acid by 12 times to achieve the lowest levelized cost per cycle on the market.

• Ultra-Fast 15-Minute Charging

  Charges to 80% SOC in under 15 minutes with high-rate 3C–5C continuous discharge, keeping multi-shift fleet operations moving with zero downtime.

• Zero-Volt Transport & Safe Storage

  Discharges fully to 0V with zero thermal risk or capacity degradation, enabling safer shipping protocols and hassle-free long-term inventory storage.

• Maximum Safety (Zero Thermal Runaway, Non-Flammable & Explosion-Proof)

  Passes harsh nail-penetration and extreme overcharge testing without fire or explosion risks, offering an operational safety margin far superior to conventional chemistries.

  
  

• Dual-Aluminum Cost Efficiency

  Replaces heavy, expensive copper foil with lightweight aluminum current collectors on both electrodes, reducing cell weight while driving down raw material costs.

• Seamless Lead-Acid Upgrade

  12 times the cycle life of lead-acid in a lighter, higher-density profile, making drop-in replacement upgrades for AGVs, forklifts, Solar Energy Storage and UPS systems effortless.

• Flexible OEM/ODM Customization

  Full-service OEM/ODM support for both raw cells and integrated BMS battery packs, tailored to meet your exact voltage, enclosure, and communication protocol needs.

Q1: What chemical systems does RJ TECH offer for sodium-ion cells, and how do I choose between them?

• NFPP (Polyanion): Engineered for stationary Energy Storage Systems (ESS), telecom backup, and microgrids. It delivers an ultra-long cycle life of 10,000+ deep cycles and extreme thermal stability.

• Layered Oxide: Optimized for light electric vehicles (2-wheelers, AGVs, forklifts) and fast-charging applications. It offers higher energy density and supports 3C–5C high-rate continuous discharge with 15-minute ultra-fast charging.

  
  

Q2: Why is the nominal voltage of RJ TECH sodium-ion cells 3.0V instead of 3.2V?

Q3: How do RJ TECH sodium-ion cells perform in extreme freezing temperatures?

Q4: What capacities and form factors are available in your prismatic cell lineup?

• Small/Medium Capacities (50Ah, 70Ah, 75Ah, 100Ah, 110Ah): Ideal for two-wheelers, AGVs, forklifts, UPS systems, and telecom backup.

• Large Capacities (150Ah, 160Ah, 170Ah, 200Ah, 210Ah, 220Ah, 230Ah, 240Ah, 280Ah): Tailored for commercial & industrial (C&I) ESS, solar energy storage, and grid-scale containerized battery banks.

  
  

Q5: How does RJ TECH guarantee Grade A cell quality and prevent second-hand or B-grade cells?

A: Every single RJ TECH cell comes with 100% original factory QR code traceability etched on the aluminum shell. We provide full factory test records (voltage, internal resistance, and capacity) per cell prior to dispatch. Furthermore, we offer pre-shipment video QC testing so B2B buyers can inspect batch consistency before final shipment.

Q6: Is it true that sodium-ion cells can be discharged to 0 Volts for safe transport and long-term storage?

A: Yes! Unlike lithium batteries which suffer permanent damage below 2.0V, RJ TECH sodium-ion cells can be discharged completely to 0 Volts without capacity loss or chemical degradation. This completely eliminates fire hazards during maritime/air transit, simplifies hazardous goods compliance, and allows zero-risk long-term warehouse storage.

Q7: What safety certifications do your cells carry for international shipping and compliance?

A: All RJ TECH sodium-ion cells pass strict safety protocols, including needle penetration, overcharge, heavy impact, and short-circuit tests with zero thermal runaway. Our cells are fully certified with UN38.3, MSDS, and CE, ensuring smooth customs clearance and regulatory compliance for imports into North America, Europe, and Asia-Pacific markets.

Q8: How does the total cost of ownership (TCO) of sodium-ion compare to Lead-Acid?

Q9: Do you support custom battery pack integration (OEM/ODM) with BMS?

Q10: What is your Minimum Order Quantity (MOQ), sample policy, and delivery lead time?

A: We welcome sample orders for lab testing and prototyping with fast dispatch within 3 days. For bulk wholesale orders, our typical lead time is 7-15 days depending on volume and custom specifications. Contact our engineering sales team with your project requirements to receive a formal RFQ and datasheet within 24 hours.
