This makes it the perfect choice for applications that require a significant burst of energy, such as cordless power tools, high-performance flashlights, and robotics.
Key Features
- High Output (High-Drain): Specifically designed to handle high current draws. It’s ideal for devices with motors, heating elements, or high-power LEDs.
- Standard 18650 Size: At 18mm x 65mm, this is the industry-standard cell for thousands of devices.
- Rechargeable: Can be recharged hundreds of times, making it an economical and environmentally friendly alternative to disposable batteries.
- 3.7V Nominal Voltage: The standard voltage for Li-ion cells, fully charging to 4.2V.
- 1300mAh Capacity: A capacity optimised for high-drain performance, balancing power output with reasonable runtime.
Common Applications
These high-output batteries are essential for:
- Cordless Power Tools: Drills, electric screwdrivers, and small saws.
- High-Power Flashlights: Tactical and high-lumen LED torches.
- Robotics: Powering motors and servos in robotic projects.
- RC Hobbies: Cars, boats, and drones that need quick bursts of power.
- Custom Battery Packs (BMS Required): Can be used to build custom power supplies for larger projects.

⚠️ Important Safety Warning
Handle with care. Lithium-ion batteries can be dangerous if misused.
- NEVER short-circuit (connect positive and negative terminals).
- DO NOT overcharge (above 4.2V) or over-discharge (below 2.75V).
- MUST be used with a proper charger rated for 3.7V Li-ion batteries.
- DO NOT use if the battery wrapper is damaged or torn.
- DO NOT incinerate, crush, or expose to extreme heat.
- For building battery packs, a Battery Management System (BMS) is required for safety.
