ZTW Backup Capacitor 25F V1 6V-12V 25A Receiver Power Backup for 3S HV Helicopter, Airplane and UAV Fail-Safe
Wider 6V-12V Voltage Range
The V1 version extends input compatibility to 6V-12V (max 13V), supporting 3S LiPo receiver batteries, 12V BEC outputs, and high-voltage servo systems that the standard 8.4V Backup Capacitor cannot handle — ideal for 700-class and larger helicopters.
Automatic Fail-Safe Power
Like the standard version, the 25F V1 instantly switches to capacitor power when the main BEC or battery fails, keeping the receiver and servos alive for a controlled landing or autorotation.
25 Farad Reserve
Stores 25 farads of energy, providing approximately 20-30 seconds of receiver and servo runtime depending on load — enough to bring a large helicopter or fixed-wing down safely.
25A Peak Output
Handles instantaneous servo current draws up to 25A, preventing brownouts during aggressive collective or cyclic inputs on high-torque HV digital servos.
Slim 19mm Profile
At 66×33×19mm and 38g, the V1 uses a longer, slimmer form factor that fits tight helicopter frames and narrow fuselages where the thicker 23mm standard version may not.
Dual Activation Modes
Supports both switch-controlled arming via a transmitter channel and automatic throttle-signal detection (50-600Hz), compatible with all major radio brands.
Redundancy for Critical Missions
The extended voltage range makes the 25F V1 suitable for professional UAVs, VTOL aircraft, and industrial rotorcraft running 3S or 12V receiver power, where power redundancy is a mission requirement rather than an option.
