2. High Capacity and Practical Energy Output
With a nominal voltage of 3.2V and a nominal capacity of at least 100Ah, the cell provides nominal energy of at least 320Wh.
Nominal energy can be estimated using the following formula:
エネルギー (うーん) = Nominal Voltage (V) × 容量 (ああ)
For this cell:
3.2V × 100Ah = 320Wh
This capacity makes the cell a potential component for battery packs used in stationary energy storage, バックアップ電源, and other compatible applications.
電池パックメーカー様向け, the final pack capacity and energy depend on the series and parallel configuration, system voltage requirements, usable depth of discharge, BMS settings, and other design factors.
3. Discharge Performance and Low AC Impedance
Discharge capability is an important consideration when selecting cells for energy storage and power applications.
Under the specified test conditions, this 3.2V 100Ah LiFePO4 cell supports a maximum continuous discharge current of 150A at 25 ± 2°C. Its maximum pulse discharge current is 300A for 30 seconds under the documented test conditions.
The cell also has a specified AC impedance of no more than 0.40mΩ at 1kHz. Low AC impedance can help battery designers evaluate electrical performance and potential internal losses, although actual pack efficiency also depends on interconnections, BMS components, 温度, and operating current.
電池パックを設計するとき, manufacturers should verify continuous and peak current requirements against the complete system specification rather than relying on a single cell rating.
4. Cycle Life and Long-Term Energy Storage
Cycle life is one of the key factors affecting the long-term value of a battery cell.
According to the cell’s documented test conditions, the cycle-life results include:
- At 100% 放電の深さ (国防総省): At least 4,500 サイクル, using an 80% end-of-life capacity criterion.
- At 90% 放電の深さ (国防総省): At least 6,000 サイクル, using a 70% end-of-life capacity criterion.
These results were obtained under specified laboratory conditions, including a temperature of 25 ± 2°C and a defined mechanical preload and charge-discharge procedure.
Actual cycle life may vary depending on operating temperature, charge and discharge current, 放電の深さ, storage conditions, pack design, and battery management settings.
B2Bバイヤー向け, it is important to compare cycle-life figures using the same test conditions and end-of-life criteria.
5. Operating Temperature and Charging Requirements
Temperature management is essential for lithium battery safety, パフォーマンス, と耐用年数.
The cell’s specified temperature ranges are:
- Charging: 0°C to 55°C
- Discharging: -30°C to 55°C
- Recommended continuous operating temperature: 10°C to 35°C
Charging is not permitted below 0°C according to the cell specification. Charging current must also be adjusted according to temperature. 例えば, the documented maximum continuous charging current reaches 100A within the 20°C to below 45°C range, while lower limits apply at other temperatures.
Battery pack designers should incorporate appropriate temperature monitoring, current limits, protective controls, and thermal management where required.
For projects operating in cold or hot environments, the full operating profile should be reviewed before selecting the cell.
6. Potential Applications of the 100Ah LFP Cell
The 3.2V 100Ah LiFePO4 battery cell may be considered for compatible battery pack designs across several application areas.
Residential Energy Storage
Battery pack manufacturers may integrate suitable LFP cells into residential storage batteries designed to store electricity from solar photovoltaic systems or support backup power.
Commercial and Industrial Energy Storage
For commercial and industrial projects, appropriately engineered battery packs can support energy management, peak-shaving strategies, およびバックアップ電源システム.
太陽エネルギー貯蔵
Solar energy storage systems use battery packs to store surplus electricity for later use. Cell selection should account for the system’s voltage, 容量, charging profile, and expected operating conditions.
Backup Power Systems

Custom Battery Pack Manufacturing
The cell may also be evaluated by battery pack manufacturers developing customized products for specific voltage, 容量, and enclosure requirements. Pack configuration and compatibility must be confirmed through engineering evaluation.
7. Important Considerations for Battery Pack Design
Selecting a suitable cell is only one step in developing a reliable battery system. Before using a 3.2V 100Ah LFP cell in a commercial project, battery pack manufacturers should evaluate the following factors.

Mechanical integration: Confirm cell dimensions, terminal design, mechanical preload, 絶縁, and enclosure requirements using the official technical drawing.
Safety and compliance: Evaluate the complete battery pack against the applicable transportation, installation, and market requirements. Cell-level test information should not be treated as proof that a finished battery pack is certified.
Careful system design helps ensure that the selected cells are appropriate for the intended application.
8. Why B2B Buyers Should Evaluate Technical Specifications Carefully
For importers, 販売代理店, energy storage system integrators, and battery pack manufacturers, purchasing decisions should be based on more than nominal capacity alone.
