Product Description The 18650 3.7V 2000mAh Original Li-ion Battery is a high-quality, dependable energy source designed for industrial and hobbyist electronics. At a verified weight of 42 grams, this cell is a "Grade A" original, ensuring that the 2000mAh capacity is accurate and the internal resistance is low. These cells are specifically engineered for high-cycle life and thermal stability, making them the preferred choice for building balanced battery packs, powering LED diving lights, or driving portable DIY robotics where reliability is more critical than raw capacity.

Key Features

  • Genuine 42g Weight: Higher weight in 18650 cells indicates a high-density metallic cathode and anode, leading to longer service life and better safety.

  • Stable Power Delivery: Maintains a steady 3.7V nominal output, reducing voltage spikes that can interfere with sensitive logic circuits.

  • High-Cycle Durability: Designed to handle 500+ charge/discharge cycles with minimal capacity loss.

  • Flat Top Design: Ideal for professional spot-welding into multi-cell configurations (2S, 3S, etc.) or for use in standard spring-loaded 18650 holders.

  • Rapid Charging Support: Optimized for efficient heat dissipation during standard charging cycles.

Technical Details

  • Dimensions: 65.0 mm (Height) x 18.2 mm (Diameter)

  • Standard Charge Current: 1000mA (0.5C)

  • Max Continuous Discharge: 2C to 5C (Application dependent)

  • Operating Temperature: -20°C to +55°C

  • Self-Discharge Rate: < 2% per month

  • Casing Material: Steel with high-quality insulation wrap

Prototyping and Engineering Tips from Robogears

  • Quality Verification: Always use the weight as a benchmark. Low-quality cells often weigh between 25g and 32g; this 42g original cell ensures you aren't using a "sand-filled" or low-capacity counterfeit.

  • Battery Pack Assembly: If you are building a 12V pack (3S configuration), always use cells of the same weight and capacity. This 2000mAh cell is perfect for 12V drones or small RC cars when paired with a 3S BMS (Battery Management System).

  • Over-Discharge Warning: As an "unprotected" industrial cell, it does not have internal circuitry to cut off power. Ensure your project has a low-voltage alarm or a protection module to prevent the cell from dropping below 2.5V, which can cause permanent chemical damage.

  • Safe Soldering: If you do not have a spot welder, use a high-heat soldering iron (60W+) and pre-tin the wire. Apply heat for no more than 2 seconds to the terminal to prevent the internal separator from melting.

Package Includes
