Product Description The 7.4V 2S Li-Po Battery Pack is a versatile power solution designed for mid-range robotics, RC vehicles, and portable electronic systems. By combining two high-performance lithium polymer cells in series, this pack delivers a punchy 7.4V nominal output that perfectly bridges the gap between single-cell 3.7V systems and larger 11.1V packs. Its slim profile and lightweight "pouch" construction make it an ideal choice for weight-sensitive applications like small drones, gliders, and compact robotic rovers requiring a steady high-current discharge.

Key Features

  • High Power-to-Weight Ratio: Delivers significant current output while maintaining a minimal physical footprint.

  • Standard 2S Configuration: Provides a nominal 7.4V (8.4V peak), ideal for many servos and motor drivers.

  • Integrated Balance Lead: Comes with a standard JST-XH 3-pin connector for precise individual cell balancing.

  • Low Internal Resistance: Minimizes voltage sag during high-torque motor maneuvers or rapid acceleration.

  • Flexible Termination: Available with standard RC connectors for quick integration into existing flight controllers.

Technical Details

  • Energy Density: High Wh/kg for extended operation

  • Max Charge Rate: 1C (Recommended for longevity)

  • Standard Discharge: 20C to 30C (Check specific batch rating)

  • Operating Temperature: -20°C to +60°C

  • Storage Voltage: 3.8V to 3.85V per cell

  • Dimensions: Approx. (Varies) x (Width) x (Length) — check batch for exact fit.

Prototyping and Engineering Tips from Robogears

  • Voltage Regulation: A fully charged 2S pack sits at 8.4V. This is perfect for the "VIN" pin on an Arduino, but too high for the 5V or 3.3V pins. Always use a high-quality buck converter or the board's onboard regulator for logic power.

  • Safety First: Never leave Li-Po batteries charging unattended. Use a dedicated 2S balance charger to ensure both cells stay at the same voltage; unbalanced cells can lead to fire hazards or reduced battery life.

  • Low Voltage Protection: Li-Po cells are easily damaged if discharged below 3.0V per cell. Use a Li-Po alarm or a programmable ESC (Electronic Speed Controller) to cut power when the pack hits 6.4V to 6.6V total.

  • Mechanical Protection: Because Li-Po pouches are soft, ensure the battery is mounted in a protected area of your robot where it cannot be punctured by screws or sharp chassis edges during a collision.
