Original Emax BLHeli Series 30A ESC with Oneshot (Original)

Emax’s BLHeli Series 30A ESC with Oneshot is designed specifically for FPV racing. The Emax series is a line of high-performance and low-cost ESCs for drone motors. Emax’s ESC’S are 100% guaranteed original and genuine products for the beginner who wants to learn how to build a drone.

EMAX BLHELI SERIES 30A ESC  is a brushless dc motor speed controller. The low output resistance greatly enhances power stability because The ESC is adapting a 2-4S Lipo battery which improves good battery life. The EMAX BLHELI ESC is programmed to start the brushless dc motor. This ESC has a greater current handling capacity which is 30A continuous and the peak current is 40A for the last 10 seconds only.

If you are wandering to build a drone and don’t know what will be the best ESC for you then worry no more, we have got your back. At Zbotic, we have everything for you to get started with your drone project.

Features :

1. Based on BLHeli firmware, further optimized to the perfect drive performance.
2. Low-voltage protection, over-heat protection, and throttle signal loss protection.
3. Separate power supply for MCU and BEC, enhancing the ESC’s ability to eliminate magnetic interference.
4. Parameters of the ESC can be set via a program card or transmitter.
5. Throttle range can be set to be compatible with different receivers.
6. Equipped with built-in linear BEC or switch BEC.
7. Max speed: 210,000 rpm for 2-pole, 70,000 rpm for 6-pole, 35,000 rpm for 12-pole.

How to Use Original Emax BLHeli Series 30A ESC with Oneshot

Solder the three motor output wires of the ESC to your brushless motor and connect the power leads to a 2–4S LiPo battery (max 16V). Plug the signal and ground wires into the corresponding ESC port on your flight controller. Perform a throttle range calibration by powering on with the throttle stick at maximum until you hear beeps, then at minimum. Finally, open your flight controller’s configuration software and select the Oneshot protocol to complete setup.
