Description
The IFR32140 LiFePO₄ (LFP) Battery Cell is a high-performance rechargeable lithium iron phosphate cell designed for reliable energy storage and high-power battery applications. With a 3.2V nominal voltage and 15Ah rated capacity, this cell provides approximately 48Wh of energy, making it suitable for building custom battery packs and energy storage systems.
The IFR32140 offers excellent performance with 1C standard charging and discharging, supporting up to 15A standard charge/discharge current. It can also handle 2C continuous charge and discharge, providing up to 30A continuous current for applications that require higher power output.
For short-duration peak loads, the cell supports up to 3C maximum charge and discharge current, reaching 45A for approximately 15–30 seconds. This makes it suitable for applications where temporary high-current demand is required.
The cell has a compact 32 × 140 mm size and uses LiFePO₄ chemistry, making it well suited for applications where safety, durability, stable performance, and long-term rechargeable operation are important.
