3.2V 15Ah LiFePO4 Battery Cell – High Capacity Lithium Iron Phosphate Rechargeable Cell

Overview

The 3.2V 15Ah LiFePO4 Cell offers a massive jump in energy density and lifespan compared to traditional lead-acid batteries. These cells are designed for high-performance applications that require a steady voltage and high discharge rates. Because LiFePO4 is thermally stable, it does not suffer from “thermal runaway” or fire risks associated with other lithium chemistries, making it the safest option for indoor solar storage and passenger electric vehicles.

Key Features

• Ultra-Long Cycle Life: Rated for over 2,000 to 3,000 charge/discharge cycles (8-10 years of daily use).

• High Safety Profile: Lithium Iron Phosphate chemistry is non-explosive and remains stable even under extreme conditions.

• Stable Discharge: Maintains a consistent 3.2V output through most of the discharge cycle, ensuring your electronics run efficiently.

• Eco-Friendly: Contains no heavy metals like lead or acid, making it a cleaner energy solution.

• DIY Ready: Perfect for building 12V, 24V, or 48V battery banks using a BMS.

Technical Specifications

Why LiFePO4 instead of Lead-Acid?

• Weight: LiFePO4 is roughly 1/3rd the weight of a lead-acid battery with the same capacity.

• Usable Power: You can safely discharge LiFePO4 up to 80-90%, whereas lead-acid should only be discharged to 50%.

• Speed: Supports much faster charging without damaging the cell internal structure.
