The 20A BLHeli Series with Oneshot ESC from Emax is made exclusively for FPV racing. A line of high-performance and reasonably d ESCs for drone motors is called the Emax series. For those who are just starting out and want to learn how to build a drone, Emax's ESCs are 100% to be and products. The 20A EMAX BLheli series ESC regulates the speed of brushless DC motors. The ESC uses a 2-4S Lipo battery, which increases battery life, therefore the low output resistance considerably improves power stability. The motor's rotational direction can be programmed to be normal, reverse, or bidirectional.Features:- The motor's rotational direction can be programmed to be normal, reverse, or bidirectional. All parameters, including the default settings, can be programmed using a programme card or a transmitter. Several safety features, such as low voltage cut-off, overheat, and throttle signal loss protection alarm to aid with device discovery: For a while, leave the throttle in the FULL ON position; the ESC will assist 5. All receivers are entirely compatible with throttle range, allowing for smooth, linear, and accurate throttle response.Specification:- Continuous Current:-20A Burst Current:- 25A Li-xx Battery:-2-4 BEC Mode:-Linear BEC Output:-2A/5VPackage
