LITTLE BEE 20A PRO 3-4S (NO BEC)

FVT Littlebee 20A Mini Brushless ESC (2-4S) for Mini Multirotor
Introduction:
One of the most Favorite ESCs finally got an upgrade! With this ESCs brand new F396 MCU processor, it is able to handle the higher RPM motors with ease. The processor on this ESC runs nearly twice as fast as the previous version, 48Mhz. It has also been equipped with a bit more flash memory and RAM. Designed to be compact and lightweight, this may be the perfect choice for many of the FPV Racers and Acro flyers! Thrust results to come. One of the smallest ESCs on the market for its size but can keep up with the bigger brothers. FVT LITTLEBEE 20A PRO ESCs supports 2-4s lipos, are mosfet driven and with fast, dedicated driver chips on a high quality PCB.
FVT Littlebee 20A ESC is using Silabs processor and fast dedicated driver chips, providing excellent freewheeling and exceptional braking capabilities.
These ESCs do not have a BEC, you will need to supply 5v power to your flight controller with a UBEC or stepdown voltage regulator.
