🔋 STF Lithium Iron Phosphate (LiFePO4) Cells: Power, Stability, and Longevity
Your choice of compact Cylindrical (6Ah) or versatile Prismatic (100Ah) power solutions.
Introducing the Siri Technofabs (STF) Lithium Iron Phosphate (LiFePO4) rechargeable cells. We offer two core formats to fit your exact power needs: the compact, high-discharge Cylindrical 32700 (6Ah) cell and the versatile, high-capacity Prismatic (100Ah) cell. Both are engineered for superior safety, stability, and an extended life cycle, making them the ultimate fit-and-forget solution for demanding applications, backed by a strong warranty.
Why STF LiFePO4? Superior Performance Across All Formats
LiFePO4 technology is the preferred choice for leading Electric Vehicle (EV) Battery Pack users, large-scale Energy Storage Systems (ESS), and critical systems requiring increased lifespan and higher performance.
Superior Safety
The phosphate-based cathode is chemically much more stable and non-combustible. It will not burn even under high temperatures or if mishandled, ensuring maximum safety for EVs and mobile robotics.
Extreme Longevity
Both cell types offer a significantly longer lifetime than Lead Acid and standard Li-ion cells, providing more than 3000 cycles under proper handling (up to 70% DOD).
High Performance
Provides stable, consistent power output with very little voltage drop during discharge, a major advantage over Lead Acid batteries.
Eco-Friendly
LiFePO4 is a non-toxic, non-contaminating material that contains no rare-earth minerals, making it an environmentally conscious choice.
