5643126 14.8V 4000mAh 60C Lithium Polymer Battery Pack, High-Performance 4S Drone Battery with Extreme Punch

Features

• Extreme Power Delivery : Enables explosive acceleration, faster climbing, and unmatched responsiveness under load with minimal voltage sag.
• High Energy & Power Combo: The 4000mAh capacity provides a solid balance between formidable runtime and extreme power output, ideal for longer race heats or practice sessions.
• Competition-Grade Construction: Utilizes premium, low-resistance cells and robust internal welding to handle sustained high-stress operation reliably.
• Optimized Thermal Performance: Designed to manage heat generation from high current draws more effectively than standard packs.

Specifications

Applications

• Competition FPV Racing Drones: Provides the ultimate “punch” and sustained high power required for winning races, aggressive freestyle maneuvers, and high-speed passes.

• High-Speed RC Models: Competition-grade 1/8 and 1/10 scale RC cars, trucks, and boats where maximum acceleration and top speed are critical.

• Extreme Performance Systems: Any application requiring a combination of high energy (59Wh) and extreme power output (240A continuous).

Warnings & Precautions

Charging

• Use a high-quality LiPo balance charger set to 4S (16.8V), ≤4.0A (1C) unless specifications allow 2C.

• Never charge unattended. Always charge in a fire-proof LiPo safety bag/container on a non-flammable surface.

Discharging

• Thermal Management is Key: High current generates immense heat. Allow the battery to cool COMPLETELY between uses. Never use it if it feels hot to the touch (>60°C).
• Monitor Voltage Aggressively: Use a precise low-voltage alarm set no lower than 3.2V per cell (12.8V for pack). Never discharge below 12.0V.
• Avoid Sustained Max Current: While rated for 60C continuous, prolonged use at the absolute limit will drastically reduce cycle life and increase risk. Use responsibly.
• Inspect Rigorously: Before and after every use, check for puffing, damage, hot spots, or loose connections. Retire any suspect battery immediately.

Storage

• ALWAYS store at ~15.2V (3.8V/cell). High-rate cells degrade rapidly if stored fully charged or fully depleted.
• Transport in a non-flammable, rigid container with terminals insulated.
• Dispose of properly at a designated battery recycling center.
