Description

46800 Lithium Iron Phosphate Cylindrical Battery Series

COMMERCIAL GRADE · PRODUCTION

Product Overview
The ATOMFAIR® 46800 LFP (LiFePO4) cylindrical cell series delivers ultra-safe, long-cycle-life energy storage in a large-format 46mm×80mm platform. Designed for high-power commercial EVs, heavy-duty trucks, and megawatt-scale stationary storage, this series features three optimized variants: high-rate (AF46800LFP01, 20C pulse), balanced (AF46800LFP02), and high-capacity (AF46800LFP03, 17.6Ah). With intrinsic olivine safety, >3000 cycle life, and excellent thermal stability, these cells provide the lowest total cost of ownership for demanding industrial and grid applications.

Key Features & Advantages
  • Large-Format 46800 Platform: Optimized 46mm×80mm form factor provides higher volumetric efficiency than 18650/21700 cells, reducing pack assembly complexity.
  • Three Power Tiers: AF46800LFP01 (20C pulse) for ultra-high-power UPS/tools; AF46800LFP02 (10C) for EV/HEV; AF46800LFP03 (17.6Ah) for cost-optimized stationary storage.
  • Absolute Safety: Olivine LiFePO4 cathode eliminates thermal runaway — passes nail penetration, overcharge, and crush tests per UL 1642.
  • Industry-Leading Cycle Life: All variants guarantee >3000 cycles to 70% capacity at 1C/1C, with calendar life exceeding 15 years at 25°C.
  • Low Self-Discharge: <3% monthly self-discharge at 25°C, enabling long-term storage without frequent maintenance charging.

APPLICATION SCOPE: Heavy-duty electric trucks, automated guided vehicles (AGVs), grid frequency regulation, solar-plus-storage, marine hybrid propulsion, and telecom backup.
PACKAGING: Reinforced industrial cardboard boxes with conductive foam inserts (4 cells per tray, 80 cells per master carton). Terminal protection caps included.
IMPORTANT NOTICE: Maximum charge voltage 3.65V ±0.05V. Do not discharge below 2.0V. For series connections above 48V, active cell balancing is mandatory to prevent voltage drift over thousands of cycles.

Frequently Asked Technical Questions

Why does AF46800LFP01 have lower capacity (12.8Ah) than AF46800LFP03 (17.6Ah)?

High-rate cells require thinner electrode coatings and higher porosity to support 20C pulses, which reduces volumetric energy density. Choose LFP01 for power-intensive applications (UPS, power tools) and LFP03 for maximum runtime in low-rate applications.

What is the recommended torque for terminal bolts?

Use M6×1.0 bolts with 6-8 N·m torque. Over-tightening (>10 N·m) may crack the aluminum terminal. Apply anti-oxidation grease for connections in humid environments.

Can I water-cool 46800 packs using standard cooling plates?

Yes, the 46mm diameter is compatible with most cylindrical cooling plates. Maintain surface contact pressure of 0.2-0.5 MPa. Maximum operating temperature 60°C; for >40°C continuous, active cooling is recommended.

What is the energy density difference between LFP and NCM in 46800 format?

ATOMFAIR 46800 LFP delivers ~130 Wh/kg, while NCM in same format reaches ~250 Wh/kg. LFP offers 2-3x cycle life and zero thermal runaway risk — choose based on application priorities.

Are these cells compatible with existing 46800 battery holders?

Yes, the AF46800LFP series follows the standard 46mm×80mm cylindrical dimensions and terminal polarity (positive on top), making them drop-in replacements for most 46800 pack designs. Always verify cell height clearance before final assembly.
