Physical and Safety Features

Housed in a ‌hard case‌, this battery offers enhanced durability against impacts and vibrations common in rugged environments. It typically includes a ‌protective circuit module (PCM)‌ to guard against overcharge, over-discharge, short circuits, and overheating. Some advanced variants integrate ‌smart technology‌, allowing users to monitor real-time health data—such as individual cell voltage, temperature, and charge cycles—via compatible smart chargers.

Common connectors include ‌IC5 or EC5 types‌, known for their low resistance and secure fit, ensuring stable power transmission during high-current draws. The typical weight is around ‌360g‌, striking a balance between robust construction and manageable weight for mobile platforms.

Application and Compatibility

This battery is widely used in:

  • High-performance RC vehicles‌: bashers, crawlers, and drift cars
  • FPV racing and freestyle drones
  • Portable industrial tools and test equipment
  • Custom robotics and DIY electronics projects

Users must verify compatibility with their device’s voltage tolerance, physical dimensions, connector type, and polarity before use to prevent damage.

Charging and Maintenance Guidance

For optimal lifespan and safety:

  • Use a ‌balance charger‌ set to ‌7.4V (2S) Li-ion/LiPo mode
  • Recommended charge rate: ‌1C (6.2A)‌, though some models support up to ‌5C fast charging‌ with proper thermal monitoring
  • Store at ‌3.8–3.9V per cell (7.6–7.8V total)‌ in a cool, dry place (0–40°C)
  • Avoid discharging below ‌6.0V (3.0V per cell)‌ to prevent irreversible cell damage
