Power and Runtime

The Lectron Pro 7.4V 300mAh 35C Li-Po battery powers compatible UMX airframes with a 2-cell 300mAh pack rated for 35C continuous and 21-amp bursts. A built-in UMX connector plugs straight into the airframe without adapters or soldering. At 16 grams and 1.77 by 0.67 by 0.51 inches, it adds minimal mass while extending flight time over smaller stock cells.

Ideal Airframes and Limits

Pilots flying UMX Timber, Beast, Carbon Cub, Blade 130 X or mCP X BL models gain a direct-fit power source that supports aggressive maneuvers through the high discharge rating. Builders needing a different voltage, a higher capacity for larger airframes, or a connector other than UMX should select another pack.

Discharge Capability

The 35C rating delivers 10.5 amps continuously with 21-amp peaks, determining whether the pack can sustain the current draw of your motor and electronics without voltage sag.
