The 6S 16800mAh 25C LiPo battery from Dupu Electronics is one of the highest-capacity 6S packs in its class—designed specifically for industrial UAVs, agricultural sprayers, large-scale mapping drones, and long-range surveillance platforms that require extended flight time without sacrificing power delivery.
With a massive 372.96Wh of energy and a robust 25C discharge rating, this battery delivers up to 420A of continuous current, enabling reliable operation under high-load conditions such as takeoff, climbing with payload, or flying in strong winds. Its rugged construction and balanced cell design ensure consistent voltage output throughout the flight, minimizing performance drop-off.
Ideal for professional users who need to cover large areas in a single sortie—such as crop spraying over hundreds of acres or infrastructure inspection across remote regions—this pack sets a new standard for endurance and reliability.

Battery Usage Precautions
Please read the following information carefully before purchase.
Before using the battery, please confirm the battery pack voltage.
The full charge voltage of each lithium polymer cell is 4.2V (high-voltage version: 4.35V).
For new batteries, avoid charging with excessive current to minimize battery degradation.
Typically, charge at around 1C current. Use a balance charger specifically designed for RC batteries and select the correct battery type mode.
Incorrect charging mode may cause unexpected hazards.- During charging, place the charger and battery in an open, unobstructed area, away from other items, and ensure someone is supervising the process.
- During discharge, use a beeper or alarm system (e.g., BB warning) to set the low-voltage cutoff per cell to approximately 3.6V to prevent over-discharge.
- When not used for a long time, store the battery at around 3.85V per cell.
Storing at full charge or low voltage can damage the battery and shorten its lifespan.
If unused for more than one month, perform a charge-discharge cycle once a month. - When not in use, disconnect the battery from the model or device, and store it in a dry, well-ventilated environment with temperature not exceeding 30°C.
For your safety, never puncture the battery casing to release gas, even if swelling occurs due to any reason. This may cause fire or explosion.
