Lumenier BLHeli_S 20A 2-in-1 OPTO ESC (20x20mm) DSHOT

Availability : Only 1 left in stock!

The Lumenier 20A 2 in 1 BLHeli_S ESC features the powerful BusyBee2 (EFM8BB21F16) chip that runs at at 48MHz 2x the speed of prevoius BLHeli_S ESCs. This BB2 processor allows the ESC to perform with incredible precision (up to 500kv eRPM support), resulting in smooth and responsive power and taking full advantage of the BLHeli_S firmware. This 2 in 1 ESC combines 2 20A ESCs into 1 board. It is low profile and compact in size, saving weight and making builds easy. These ESCs are OPTO (no BEC) and come with motor, signal and power wires for your convenience. The ESC features new BLHeli_S firmware pre-installed on them. They are compatible with PWM, Oneshot125, Oneshot42, and Multishot protocols. Simply enable the feature in the flight controller software and the ESC will automatically match it. This ESC also supports DSHOT protocol by flashing DSHOT firmware.

These BLHeli_S ESCs feature hardware PWM controllers running at 36KHz, which is more than double of previous software PWM ESCs at 16KHz. This results in ultra smooth throttle response and near silent motor operation.

Building a quadcopter will require 2x of these 2-in-1 ESCs to support 4x motors.
