This is the latest version of the SpeedyBee BLS ESC – the PCB has bee refined, using increased copper thickness and enhanced MOSFET specifications. There’s also the addition of an aluminium alloy heat sink to ensure efficient MOSFET heat dissipation for stable ESC output.
A high quality ESC for a great price. The SpeedyBee BLS 4in1 ESC is an excellent choice for a wide range of builds, from power hungry freestyle drones, to long range cruisers. Each ESC motor output can withstand a true continuous current of 60A and 80A peak for 10 seconds. Built with the robust BB21 MCU, this ESC runs BLHeli_S firmware and operates under the Dshot 300/600 protocol. It features Japan made TDK filtering SMT capacitors and the ESC is built with a TVS protective diode to absorb the voltage spike when you plug in the battery, or during crashes that block your props. SpeedyBee also provide a humongous 1000uF low ESR capacitor, ensuring clean data from the gyro to the FC. Lastly, the ESC has large motor pads for easy soldering.
