IFR32140 3.2V 15Ah LiFePO4 High-Capacity Cylindrical Battery Cell

The IFR32140 3.2V 15Ah LiFePO4 Cylindrical Battery Cell (48Wh) is a heavy-duty, high-capacity industrial power storage solution designed for demanding energy setups. Engineered with advanced Lithium Iron Phosphate (LFP) technology, this premium cell offers the ultimate combination of dense power storage, unparalleled thermal stability, and an exceptionally long service life compared to standard Lithium-Ion or Lead-Acid alternatives.

Safety is the cornerstone of Lithium Iron Phosphate chemistry. Unlike traditional Li-ion cells, the chemical structure of this LiFePO4 battery is highly resistant to thermal runaway, ensuring safe operations even under high temperatures or physical stress. Furthermore, it boasts an incredible cycle life, maintaining high performance through 2,000 to 3,500+ deep charge-discharge cycles before experiencing significant capacity drop. This longevity translates directly into years of maintenance-free service.

• High Energy Density: A single cylindrical cell packs a massive 15,000mAh (15Ah) capacity, delivering 48 Watt-hours (Wh) of clean energy.
• Steady Discharge Platform: Operates at a flat 3.2V nominal discharge curve, ensuring connected electronics receive a steady, predictable supply of voltage throughout the majority of the discharge cycle.
• Robust C-Rating Performance: Supports a 15A (1C) continuous discharge rate and can handle brief peak power demands up to 45A (3C), making it excellent for heavy startup loads in power systems.

The 32140 designation refers to its precise physical footprint: 32mm in diameter and 140mm in height. This standardization makes it incredibly easy to configure into custom battery matrices using plastic spacers and pure nickel strips. With flat-top terminals, these cells are optimized for industrial spot-welding or laser welding to ensure ultra-low resistance across the pack.

• Solar Energy Storage Systems: Building long-lasting off-grid or hybrid residential solar battery banks.
• Inverters & Backup Power (IPS/UPS): Replacing heavy, short-lived lead-acid batteries with a lightweight, fast-charging alternative.
• Light Electric Vehicles (EVs): Assembling power packs for electric rickshaws, e-bikes, mobility scooters, and golf carts.
• Industrial Robotics & Telecom: Supplying rugged power backup for base stations, telecommunication hubs, and outdoor automated machinery.
