Product Description The 18650 2200mAh Li-ion battery is a high-performance, rechargeable power cell designed for high-drain applications and portable electronics. Balancing a lightweight 29g design with a reliable 2200mAh capacity, this battery provides the consistent voltage required for everything from powerful flashlights and power banks to DIY EV prototypes and robotics. Its standardized 18mm x 65mm form factor ensures compatibility with a wide range of battery holders and charging modules.

Key Features

  • Optimized Energy-to-Weight Ratio: Delivers high capacity at just 29g, perfect for weight-sensitive drones or rovers.

  • Stable Power Delivery: Maintains a flat discharge curve for consistent performance across various hobbyist electronics.

  • Standardized Form Factor: Fits all industrial-standard 18650 chargers and holders.

  • Extended Cycle Life: Designed for hundreds of charge/discharge cycles with minimal capacity loss.

  • Versatile Integration: Can be used as a single cell or spot-welded into multi-cell packs for higher voltage or capacity.

Technical Details

  • Dimensions: 18 mm (Diameter) x 65 mm (Height)

  • Standard Charge Current: 0.5C (1100mA)

  • Max Discharge Current: Typically 1C to 2C (Check specific batch rating)

  • Internal Resistance: Low resistance for efficient energy transfer

  • Top Style: Flat Top (Standard for pack assembly)

  • Protective Circuit: Unprotected (External BMS recommended)

Prototyping and Engineering Tips from Robogears

  • BMS Requirement: Since this is an unprotected cell, always use a Lithium Battery Protection Board (BMS) to prevent overcharging, over-discharging, and short circuits. This is critical for safety and battery longevity.

  • Charging Safety: Only use chargers specifically designed for Lithium-Ion 3.7V/4.2V chemistry. Never leave batteries charging unattended, and avoid charging near flammable materials.

  • Soldering vs. Spot Welding: To build a battery pack, spot welding nickel strips is the professional method. If soldering, be extremely fast and use a high-wattage iron to avoid overheating the internal chemistry, which can permanently damage the cell.

  • Voltage Balancing: If connecting multiple cells in series or parallel, ensure all batteries are at the exact same voltage level before assembly to prevent high current surges between cells.

Package Includes

  • 1 x 18650 3.7V 2200mAh Li-ion Rechargeable Battery
