Product Specification

3S 11.4V 3250mAh 50C LiPo Battery - 37Wh Compact Cube for 3-5 Inch FPV Drones, Cinewhoop & RC Airplanes, High Power/Size Ratio

Features

• High Power-to-Size Ratio: Exceptional 50C continuous discharge rating delivers robust power for aggressive flying, despite its compact physical dimensions, ensuring minimal voltage sag during high-throttle maneuvers.

• Universal Air Travel Friendly: At 37.05Wh, this battery significantly undercuts common 100Wh airline carry-on limits, simplifying logistics for traveling pilots and professionals.

• Versatile Performance Profile: Suits a wide range of uses from spirited freestyle flying to efficient long-range cruising, thanks to its balanced capacity and high discharge capability.

• Robust & Reliable: Built with high-discharge LiPo cells and quality silicone wires, designed to withstand the vibrations and occasional impacts common in drone operations.

Specifications

Applications

• 3-5 Inch FPV Drones: The standard voltage for many 3" and 4" micro/mini quads, and a popular choice for lighter 5" builds focusing on agility and lower weight.

• FPV Whoop & Cinewhoop Drones: Provides ample power for ducted propeller drones used for indoor/outdoor acrobatics or smooth cinematic filming.

• Portable Ground Equipment: Powers handheld tools, advanced camera gimbals, LED lights, and custom electronic projects needing a high-current, rechargeable battery pack.

• Educational & Competition Robotics: A reliable power source for mid-sized combat or mobility robots.

Warnings & Precautions

Charging

• Dedicated Charger: ONLY use a programmable LiPo balance charger. Confirm settings: Battery Type: LiPo, Cells: 3S (11.1V).

• Charge Rate: For longevity, use 1C (3.25A). Do not exceed 3C (9.75A) even if capable.

• Never Unattended: ALWAYS monitor the charging process. Charge in/on a LiPo Safety Bag or fireproof container placed on a non-flammable surface away from combustible materials.

• Mandatory Balance Charging: EVERY charge cycle must utilize the JST-XH balance lead to maintain cell health and safety.

• Immediate Termination: Disconnect immediately if the battery swells, heats excessively (>45°C), emits odor/smoke, or shows any physical breach.

Discharging

• Voltage Guardrails: NEVER discharge below 9.0V (3.0V per cell). NEVER charge above 12.6V (4.2V per cell). Use a low-voltage alarm or telemetry.

• Temperature Management: Operate within -10°C to 60°C. Optimal range is 15°C-40°C. Allow to cool to ambient temperature before charging.

• Physical Integrity: Inspect before each flight/use for swelling, punctures, or connector damage. DO NOT USE if compromised.

• Short Circuit Prevention: ALWAYS install protective caps on the XT60 connector when not plugged into a device. Keep terminals clean and isolated.

• Environmental Protection: Keep dry. Avoid prolonged exposure to direct sunlight, moisture, or extreme temperatures.

Storage

• Storage State of Charge: For storage >48 hours, set to Storage Voltage (3.80V-3.85V per cell / 11.4V-11.55V total) using your charger's storage function.

• Safe Storage: Store in a cool, dry environment (10°C-25°C) inside a fireproof container. Avoid storing fully charged or fully depleted.

• Transportation: For air travel, terminals must be protected from short circuits. As a <100Wh battery, it is typically permitted in carry-on baggage in reasonable quantities (verify with airline).
