Key Features and Advantages

1. ✅ High Continuous Discharge (30A)
   Perfect for motors, power tools, and energy-intensive circuits.

2. 🔋 Optimal Capacity (2500mAh)
   Offers a good balance between runtime and current output.

3. 🔁 Rechargeable and Long Lifecycle
   Can be recharged hundreds of times with minimal capacity degradation.

4. 🔒 Thermal and Circuit Protection (optional with PCM)
   Maintains stability under high load conditions, especially with BMS or protected versions.

5. 🌱 Eco-Friendly Alternative to Disposable Cells
   Reduced environmental impact with lower waste output over time.

The 12C rating means the battery can discharge at 12 times its capacity, i.e., 2500mAh x 12 = 30,000mA (30A) continuously without overheating or dropping voltage significantly.

This high-drain capability makes it an excellent power source for:

• Electric bicycle, skateboards

• RC vehicles and drones

• Vape mods

• High-power LED torches

• Cordless tools

For applications that require bursts of high energy, this 18650 30A lithium battery delivers consistent and safe performance.
