Rechargeable lithium-ion 18650 cell Samsung INR18650-29E-FT 2750mAh 3.7V with welded nickel tabs, with storage case

Single Samsung INR18650-29E-FT lithium‑ion cell with a nominal capacity of 2750 mAh and nominal voltage of 3.7 V. The cell is delivered with pre-welded nickel contact tabs suitable for spot welding and packed in a protective storage case for safe handling and transport. Designed for applications that require a high-energy 18650 format from a reputable manufacturer, this rechargeable cell is intended for integration into battery packs, DIY projects and portable electronic devices.

Advantages

The Samsung INR18650-29E-FT combines a balance of energy density and discharge capability, offering 2750 mAh in the standard 18650 size. Welded nickel tabs simplify spot-weld assembly and reduce preparation time when building multi-cell packs. The protective storage case prevents short circuits and mechanical damage during storage and transport. Being a rechargeable lithium-ion cell, it supports repeated charge/discharge cycles when used with appropriate charging and battery management systems.

Suitable for

• Battery pack assembly for power tools, e-bikes and other modular packs
• DIY power banks and portable chargers
• Flashlights, headlamps and portable lighting
• Hobby electronics, RC models and custom battery solutions
• Replacement cells in multi-cell devices after checking compatibility

How to use

Handle the cell following standard lithium‑ion safety procedures. Use appropriate spot‑welding equipment to attach the nickel tabs to cell holders or bus bars; avoid soldering directly to the cell body. Assemble cells into packs with proper cell orientation, balancing and an appropriate battery management system (BMS). Charge and discharge the cell within recommended voltage and current limits, and use a compatible charger designed for lithium‑ion cells. Inspect the cell and tabs for damage before assembly and discard any cell with visible dents, leakage or compromised insulation.

Usage recommendations

Store cells in the provided protective case, in a cool, dry place away from direct sunlight. Maintain partial charge (around 30–50%) for long‑term storage, and avoid exposing cells to temperatures outside the manufacturer’s recommended range. Always implement appropriate overcurrent, overcharge and temperature protection in any pack built from these cells.
