Engineered for extreme power and rapid response, this 3.85V 20Ah drone battery is built for UAV applications demanding instant thrust, heavy payloads and aggressive maneuvering. Its high-voltage, ultra-high-rate lithium polymer design and lightweight, 8.8mm slim form factor make it easy to integrate into large airframes, while an ultra-low 1.5mΩ internal resistance and a wide -40°C to +55°C operating range ensure stable, dependable power in diverse environments. Whether you're building delivery, agricultural, police, or industrial drones, this battery delivers outstanding performance and peace of mind.

Key Features & Core Advantages

• High Capacity & Energy:Stores20Ah / 77Wh in a single high-voltage soft cell (21Ah typical) for longer flight time and extended routes.
• Ultra-High Discharge Rate: Delivers up to 200A (10.0C) continuous, with 15C for 30s and a 25C 1s pulse, providing instant thrust for heavy loaded takeoff, fast climb and sharp maneuvers.
• Extreme Temperature Range: Discharges reliably from -40°C to +55°C, retaining 60% capacity at -20°C, with stable startup and output in freezing winters and hot climates.
• Fast, Efficient Charging: Standard charge at 10A (0.5C) finishes in approx 5–6h; supports up to 40A (2.0C) for quick turnaround between flights.
• Ultra-Low Internal Resistance: AC impedance of ≤1.5mΩ keeps output voltage stable and minimizes heat under high load.
• Lightweight & Slim: Weighs only ~327g in an 8.8mm thin soft pack, helping maximize payload and flight efficiency.
• Certified & Safety-Tested:CE and RoHS compliant, validated through short-circuit, thermal shock and over-charge/discharge tests.
