Rechargeable LiFePO4 cell Beltrona 18650XH2.54 3.2V 1500mAh, cylindrical 18650 size

Beltrona 18650XH2.54 is a single-cell rechargeable LiFePO4 (lithium iron phosphate) battery in the cylindrical 18650 format with a nominal voltage of 3.2 V and a rated capacity of 1500 mAh. The cell is designed for use in battery packs, portable lighting, backup power modules and various DIY electronics projects that require a stable low-voltage LiFePO4 source. Compared with typical lithium‑ion cells, this LiFePO4 chemistry provides improved thermal stability, lower risk of thermal runaway and a longer cycle life when charged and discharged within specified limits. The cell features a 2.54 mm tab spacing suitable for spot‑welding or soldering to compatible holders and pack assemblies when proper procedures are followed.

Advantages

The Beltrona 18650XH2.54 offers a consistent nominal voltage of 3.2 V and a moderate 1500 mAh capacity that balances energy density and longevity. LiFePO4 chemistry delivers stable voltage under load and greater cycle durability compared with many other lithium cell types, reducing the need for frequent replacements in long‑life applications. The cylindrical 18650 form factor is widely supported by holders, chargers and pack designs, simplifying integration into existing systems. The cell’s design supports standard LiFePO4 charging profiles, which helps maintain performance and safety when using compatible chargers.

Suitable for

• Battery packs for portable devices and power banks
• Flashlights and portable lighting
• Backup power modules, UPS and memory retention circuits
• DIY electronics, hobbyist projects and custom battery assemblies
• Power tools and equipment designed for LiFePO4 cells (with appropriate pack design)

How to use

Install the Beltrona 18650XH2.54 cell in a compatible holder or assemble into a pack using appropriate mechanical and electrical practices. Charge the cell only with chargers that support LiFePO4 profiles (constant current/constant voltage to the recommended termination voltage) and observe manufacturer-recommended charge and discharge limits. When spot-welding or soldering tabs, follow safe temperature and technique guidelines to avoid damaging the cell. Use proper cell balancing in multi-cell packs and include suitable protection circuitry (overcharge, overdischarge and short-circuit protection) when designing battery systems.

Usage recommendations

Store and operate the cell within recommended temperature ranges, avoid deep discharges and do not use chargers intended for other lithium chemistries unless they have a specific LiFePO4 mode. Inspect cells for physical damage before use and replace cells that show swelling, leakage or other signs of failure. For pack construction, include a battery management system (BMS) to ensure safe charging, discharging and cell balancing.
