Product Description The 3.7V 6000mAh Lithium Polymer battery is a massive energy storage solution designed for applications requiring long runtimes without the bulk of traditional battery packs. Packing 22.2Wh of energy into a slim, lightweight pouch, this battery is the perfect choice for high-end power banks, portable outdoor lighting, solar energy storage, and autonomous robotic platforms. Its flat discharge curve ensures that your electronics receive steady power for extended periods, making it a reliable backbone for any professional-grade DIY project.

Key Features

  • Massive Energy Density: 6000mAh capacity provides exceptional runtime for portable devices.

  • Ultra-Slim Profile: Designed to fit into flat enclosures where cylindrical cells cannot.

  • Stable Power Delivery: Maintains a consistent voltage throughout the discharge cycle.

  • Low Self-Discharge: Retains charge effectively over long periods of inactivity.

  • Integrated Protection: Most units feature a built-in PCM (Protection Circuit Module) to prevent over-charge and over-discharge.

Technical Details

  • Standard Charge Current: 0.2C to 0.5C (1.2A to 3.0A)

  • Max Discharge Current: ~1C (6.0A) - Ideal for sustained power

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

  • Storage Temperature: -10°C to +45°C

  • Dimensions: Approx. (Thickness varies) x (Width) x (Length) — check specific batch for millimetric precision.

  • Cycle Life: 500+ full charge-discharge cycles.

Prototyping and Engineering Tips from Robogears

  • Charging Requirements: Always use a dedicated Li-ion/Li-Po charger. Given the large 6000mAh capacity, we recommend a charger capable of at least 1A output (like a high-current TP4056 module) to avoid excessively long charging times.

  • Protection First: Even with an internal PCM, always ensure your project has a low-voltage cutoff. Drawing a Li-Po below 3.0V can cause permanent chemical damage.

  • Physical Safety: Never puncture or bend the battery pouch. Li-Po batteries are sensitive to physical damage; ensure the battery is mounted in a rigid compartment or protected by a hard casing within your robot or device.

  • Parallel Expansion: If you need even more capacity, you can connect two of these in parallel (Positive to Positive, Negative to Negative), but only if both batteries are at the exact same voltage level before connection.

Package Includes

  • 1 x 3.7V 6000mAh Lithium Polymer (Li-Po) Battery
