✏️ Description 

The Xiaolu 32140 15Ah LiFePO₄ cell is a high-quality cylindrical battery cell engineered for stable, safe, and long-duration use. With its 3.2 V nominal voltage, this cell is excellent for building battery packs for electric vehicles, solar storage systems, UPS backups, and other energy-demanding applications.

Key advantages include:

Safer Chemistry: LiFePO₄ is known for improved thermal stability, reduced risk of fire/thermal runaway compared to many Li-ion chemistries.

Durable & Long Cycles: Designed to offer 2,000+ cycles under proper charge/discharge conditions.

Moderate Discharge (2C): Delivers a balance of sustained current output (≈30 A) without excessive stress on the cell, making it suitable for many EV / e-bike applications.

Low Internal Resistance & Good Voltage Stability: Ensures efficient energy delivery even under load.

Compact & Standard Format: Fits into standard 32140 cylindrical form factor (≈33.2 × 140 mm), making it compatible with many DIY pack designs.
