Applications

  • 7-inch FPV Freestyle – Aggressive acrobatics and power loops

  • Long-Range Cruising – Efficient power for extended flight times

  • Cinematic Drones – Smooth, responsive control for aerial filming

  • Heavy-Lift Builds – 1250W max power supports additional payload

1.Do not short-circuit the battery; if the wire is broken, be sure to wrap it securely.

2.When assembling the aircraft battery, ensure that the wires are securely tied to prevent damage from propeller blades.

3.Do not over-discharge the battery; generally, do not let a single-cell battery drop below 3.6V (set an alarm buzzer or keep track of flight time).

4.After using the battery, if it will not be used for some time, charge it to 3.8V per cell for storage.

5.Do not exceed the input voltage specified on the label to avoid damaging the motor.
