The cell must be stored in a cool, dry environment and never subjected to temperatures outside -40°C to 60°C during operation or -10°C to 45°C during charging. Safety precautions require avoiding disassembly, deformation, short-circuiting, or incineration, and all battery packs must incorporate appropriate cell balancing and protection circuitry.
- Storage Conditions: Store cells in a cool, dry environment and avoid prolonged exposure to temperatures above 60°C or below -40°C.
- Charging Temperature Range: Charge the cell only when the ambient temperature is between -10°C and 45°C.
- Discharging Temperature Range: Discharge the cell only when the ambient temperature is between -40°C and 60°C.
- Safety Prohibitions: Do not disassemble, deform, short-circuit, or incinerate the cell.
- Protection Circuitry Requirement: Ensure appropriate cell balancing and protection circuitry is used in any battery pack assembly.
How does the maximum continuous discharge current of the ATOMFAIR 3.2V 25Ah wide-temperature cell change at sub-zero temperatures compared to room temperature?
At -40°C to 0°C the cell supports 5C continuous discharge, while at 0°C to 60°C it supports up to 15C continuous discharge. This trade-off is specified in the technical data: 5C discharge at low temperatures (-40°C~0°C) and 15C discharge at 0°C~60°C. The cell maintains 5C discharge even at -40°C, ensuring high-power delivery in extreme cold.
What is the minimum charging temperature for the ATOMFAIR 25Ah prismatic cell, and does it require preheating below that threshold?
The minimum charging temperature is -10°C, as stated in the specification: charging temperature range -10°C ~ 45°C. The source does not mention preheating requirements, but if charging below -10°C is required, external heating would be necessary to stay within the safe charging window. The cell's wide-temperature design focuses on discharge down to -40°C, but charging is only specified down to -10°C.
What are the recommended storage conditions and safety precautions for the ATOMFAIR 3.2V 25Ah LFP prismatic cell in battery pack assembly?
Store cells in a cool, dry environment and avoid prolonged operation above 60°C or below -40°C. Do not disassemble, deform, short-circuit, or incinerate. The notice emphasizes using appropriate cell balancing and protection circuitry in pack assembly. The cells are delivered in industrial standard sealed containers with individual protective insulation.
The ATOMFAIR 3.2V 25Ah prismatic LFP cell delivers rated discharge at -40°C and 5C rate under extreme cold, with 15C continuous discharge at ambient temperatures, but cycle life degrades sharply at sub-zero charging conditions and the cell requires external protection circuitry for safe pack integration.
Positive
- Wide temperature operation: Reliable discharge from -40°C to 60°C and stable charging from -10°C to 45°C, ensuring uninterrupted performance across diverse climatic conditions.
- High rate capability: Supports 6C continuous charging and up to 15C continuous discharge at 0°C~60°C, with 5C discharge at -40°C~0°C, providing exceptional power delivery for demanding applications.
Trade-offs
- Reduced cycle life at sub-zero temperatures: At -10°C the cell delivers only ≥200 cycles (0.2C/0.5C), significantly lower than the ≥3000 cycles at 25°C, limiting longevity in continuous cold-charge operation.
- Requires external protection and balancing: The cell must be integrated with appropriate cell balancing and protection circuitry in battery pack assembly to prevent damage from overcharge, deep discharge, or imbalance.
