XDFly Backup Capacitor 25F 8.4V (9.0V Max)
The XDFly 25F Backup Capacitor adds a safety buffer and voltage stabilization to high-load RC setups. Sized to provide emergency control time (e.g., hard-stick inputs during an auto) in case of BEC failure or LiPo disconnect, it also smooths transient voltage dips under peak current, helping protect receivers, FBL units, and servos.
Key Features
- Emergency reserve: provides extra control time to complete an auto if power is interrupted.
- Voltage buffering: reduces brownouts and keeps electronics stable during high current spikes.
- 25A capability: designed to support demanding helicopter and high-load aircraft systems.
- Compact form factor: easy to mount near ESC/FBL inside most frames.
- Simple integration: wire in parallel with the BEC/receiver bus per your system guidelines.
