This is the DJI E600/E800 20-Amp Injection Molded ESC. New in-mold injection technology makes the 20A ESC more robust and water resistant. Highly efficient, quick response algorithms provide drastic optimization of both your motors and propellers, and give you enhanced maneuverability and stability in wind or during descent.
This UBEC is an external switching mode DC-DC regulator; it draws DC voltage from 2-6S LiPo battery, drops it to a voltage level that is suitable for your receivers and other electronic devices, and keeps providing the stable current output of 3Amp. It’s compatible with different brands of ESCs.
The 8A-UBEC is a switch-mode DC-DC regulator works with a 2-3S Lipo battery, it outputs a consistent safe voltage for your receiver, gyro and servos. It is very suitable for large scale RC models with many servos such as nitro powered RC helicopters and airplanes.
