High-Performance 4S Drone Battery: 2500mAh with 60C Discharge

Features

• High Energy Density: Offers a favorable balance of capacity and physical size, providing substantial energy  for extended runtime.
• Integrated Protection & Safety: Equipped with a standard Protection Circuit Module (PCM) that safeguards against common fault conditions like overcharge, over-discharge, overcurrent, and short circuits.
• Long Cycle Life: Utilizes high-quality lithium-ion cells capable of over 500 charge-discharge cycles while maintaining performance.
• Stable Discharge Performance: Provides a relatively flat discharge voltage curve for consistent device operation throughout most of the discharge cycle.

Specifications

Applications

• Portable Consumer Electronics: Handheld scanners, portable printers, high-power LED work lights.
• Instrumentation & Tools: Cordless power tools, precision measuring instruments, environmental monitoring equipment.
• DIY & Hobbyist Projects: Robotics, drone components, custom portable power supplies.
• Backup Power: Emergency lighting systems, small-scale UPS for critical electronics.

Warnings & Precautions

Charging

• Use the Correct Charger: ALWAYS use a Li-ion specific charger designed for batteries and the CC/CV method. 
• Monitor Charging: Do not leave batteries charging unattended for extended periods or overnight. Disconnect once fully charged.
• Charge in a Safe Area: Charge on a non-flammable surface in a well-ventilated area. Keep away from heat sources, direct sunlight, and flammable materials. Never charge in exit routes like hallways.

Discharging

• Prevent Over-Discharge: Do not discharge the pack below the recommended cut-off voltage (typically 11.0V - 12.0V for the pack). Deep discharge can cause permanent damage.
• Avoid Extreme Loads: Do not exceed the specified maximum continuous discharge current (7.5A). Excessive current can lead to overheating.
• Temperature Management: Allow the battery to cool to ambient temperature after heavy use before recharging. Do not operate or charge a battery that is hot to the touch.

Storage

• Storage State: For long-term storage (>1 month), partially charge the battery to approximately 40-60% capacity (about 3.8V per cell). Store in a cool, dry place within the recommended temperature range.
• Inspect before each use. Do not use if you notice swelling, deformation, leakage, strange odors, or damage to the casing.
• Never puncture, crush, disassemble, or immerse the battery in water.
• Prevent short circuits by never allowing the metal terminals to contact conductive materials like keys or tools.
