Product Overview
|
| The ATOMFAIR® 46145 LFP (LiFePO4) cylindrical battery series delivers industry-leading safety, ultra-long cycle life, and flexible power options for demanding commercial energy storage and electric vehicle applications. Leveraging advanced nano-phosphate cathode technology and low-impedance tabless design, these cells provide exceptional thermal stability, intrinsic abuse tolerance, and outstanding cell-to-cell consistency. The series offers three optimized variants: high-power (AF46145LFP01, 5C/20C, 25Ah), balanced (AF46145LFP02, 3C/10C, 28Ah), and high-energy (AF46145LFP03, 2C/3C, 33.3Ah). Whether for heavy-duty EV traction, grid-scale storage, industrial UPS, or marine propulsion, the 46145 LFP platform delivers superior reliability and competitive pricing for scaled deployment. |

Key Features & Advantages
|
- Ultra-Safe LFP Chemistry: Intrinsic thermal stability, zero risk of thermal runaway, and exceptional tolerance to overcharge/over-discharge — ideal for high-reliability applications.
- Three Optimized Variants: Choose from high-power (AF46145LFP01, 5C/20C, 25Ah) for rapid acceleration and regenerative braking, balanced (AF46145LFP02, 3C/10C, 28Ah) for general EV and storage, or high-energy (AF46145LFP03, 2C/3C, 33.3Ah) for extended runtime stationary systems.
- Extended Cycle Life: Exceeding 3000 cycles at 70% state-of-health ensures >10 years of service in daily cycling applications, significantly reducing total cost of ownership.
- 46145 Format Advantages: Large-format cylindrical cells (46mm x 145mm) minimize passive components, simplify pack assembly, and improve thermal management compared to smaller form factors.

APPLICATION SCOPE: Heavy-duty electric vehicles (buses, trucks, AGVs), grid-scale energy storage systems, residential battery backup, industrial UPS, marine propulsion, and high-power two-wheeler modules.
PACKAGING: Industrial moisture-barrier cartons with anti-static dividers. Each cell is individually insulated. Packaging dimensions vary by model; contact sales for detailed specifications.
IMPORTANT NOTICE: To maximize cycle life, operate cells within recommended voltage window (2.5V – 3.65V) and avoid sustained operation at temperature extremes (>60°C or < -20°C). Always use a dedicated LFP BMS with cell balancing.

Frequently Asked Technical Questions
|
What are the differences between the three AF46145LFP models?
The AF46145LFP01 is optimized for high power (5C charge / 20C discharge, 25Ah) — suitable for rapid acceleration and regenerative braking. The AF46145LFP02 offers balanced performance (3C/10C, 28Ah) for general EV and storage. The AF46145LFP03 prioritizes energy density (2C/3C, 33.3Ah) for extended runtime in stationary storage.
What is the expected calendar life of these LFP cells?
Accelerated aging tests predict >15 years calendar life at 25°C, 80% SOH retention after 10 years under typical cycling profiles. LFP chemistry inherently resists calendar aging better than NMC.
Can I parallel different AF46145LFP variants in a single pack?
Mixing variants is not recommended due to different internal resistance and capacity profiles. For multi-string applications, use identical models per parallel group. Contact our engineering team for custom pack design support.
What safety certifications are available for this series?
All cells comply with UN38.3, UL 1642 (USA), IEC 62133-2:2021 (international), and CE. Batch-level test reports for nail penetration, overcharge, and thermal propagation are available upon request.
What is the recommended torque for terminal connections?
The 46145 cylindrical cells feature standard M6 threaded terminals. Recommended torque: 8–10 N·m for busbar connections. Use anti-oxidation paste on aluminum terminals to prevent galvanic corrosion.
