Product Description

Power your mobile applications with the 11.1V 3S 18650 Li-ion Battery Pack. This ready-to-use power solution is built using high-quality 18650 lithium cells, providing a stable 11.1V output suitable for a wide range of DC electronics. At Robogears, we recommend this pack for its plug-and-play convenience, featuring a standard 5mm DC jack that eliminates the need for complex soldering or wiring. The internal Battery Management System (BMS) ensures safe operation by protecting the cells against common electrical faults. Whether you are building a wireless rover or a portable lighting system at your Pimpri workshop, this compact battery pack offers the high energy density and reliability required for modern STEM and robotics projects.

Detailed Key Features

  • Integrated 5mm DC Connector: Features a universal 5mm DC barrel jack for easy connection to DC-to-DC converters, motor drivers, and power adapters.

  • Safe & Stable Power: Includes a built-in BMS that monitors individual cell voltages to prevent overcharging, over-discharging, and short-circuit damage.

  • Compact 3S Configuration: The 3-series cell layout provides a nominal 11.1V (peaking at 12.6V), making it a perfect drop-in replacement for bulky 12V lead-acid batteries.

  • Rechargeable & Eco-Friendly: High-cycle life 18650 cells allow for hundreds of charge/discharge cycles, offering a cost-effective and sustainable power source.

  • Industrial Grade Wrapping: Encased in high-quality blue/black PVC heat shrink tubing for insulation and protection against physical wear.

All Technical Details

  • Stability: Precision-matched cells ensure uniform discharge and consistent power delivery throughout the cycle.

  • Ease of Use: Designed for immediate integration into projects using standard DC power ports.

  • Lightweight Profile: Offers superior power-to-weight ratio compared to Ni-MH or Lead-Acid alternatives.

  • Versatility: Suitable for Arduino projects, RC vehicles, LED strips, and handheld test equipment.

Prototyping & Engineering Tips (Robogears Exclusive)

  • Correct Charging: For your work at Pimpri, always use a dedicated 12.6V 3S Li-ion Charger. Never use a standard 12V power adapter for charging, as it lacks the required 12.6V constant current/constant voltage (CC/CV) profile needed for Lithium safety.

  • Voltage Awareness: The pack ranges from 9.0V (fully discharged) to 12.6V (fully charged). Ensure your motor drivers or microcontrollers (like Arduino) are using a voltage regulator if they cannot handle the 12.6V peak.

  • Mounting Protocol: Secure the battery pack using double-sided foam tape or a dedicated battery holder. Avoid using sharp metal screws near the pack to prevent accidental punctures to the Li-ion cells.

  • Temperature Monitoring: If the pack feels excessively hot during high-torque robotic movements, it may be exceeding its continuous discharge rating. Consider using two packs in parallel to distribute the current load.

Package Includes

  • 1 x 11.1V 3S 18650 Li-ion Battery Pack (with 5mm DC Jack)
