Overview

This one is new model Lfp 33140/40135

IFR33140 3.2V 15Ah is a cylindrical lithium iron phosphate (LiFePO4) battery with standard dimensions of 33mm diameter × 140mm height. It is widely used in electric vehicles, solar energy storage systems, emergency power supplies, and industrial equipment.

Our LiFePO4 cylindrical cell is engineered to deliver superior energy density and reliability in a compact design. With a standard diameter of 18/21/26mm and length of 65/70/140mm, it fits seamlessly into various battery pack configurations. Built with a pure lithium iron phosphate cathode and copper-nickel plated anode, the cell ensures stable ion transmission and low internal resistance (≤3mΩ). The rugged steel casing provides IP67 waterproof protection, while the precision-welded terminals enable easy series/parallel connections. Operating within a wide temperature range of -20°C to 60°C, this cell maintains 95% capacity retention after 3,000+ charge-discharge cycles, outperforming traditional lithium-ion cells by 2X cycle life.
