A light, small and powerful ESC for mini quadcopters and other multirotor craft, designed to work with 2s-4s lipo batteries. The Spedix ES25 weighs just 5.9g and supports a maximum current of 25A whilst retaining a small size of just 12.8×25.8×5mm. The ES25 is powered by a high-performance EFM8BB21 MCU.

The filter circuit is comprised of 12 low ESR capacitors, which reduces voltage ripple and provides high system stability and reduced video interference for your mini quad.

This is a superbly spec'd compact ESC manufactured from quality components and provides ultra-smooth throttle response by utilising BLHeli_S firmware. Compared with their 30a high voltage esc, the ES25 is about 2g lighter and supports up to 4s, whereas the ES30 supports 6s. Both support up to Dshot 600. If you want to make the jump to a 32-bit ESC and grab the corresponding Dshot 1200 support, look at the GS30 (4s) and GS35 (6s) which are both BLHeli_32 variants.

This ESC supports Dshot "as is". There is no need to remove any caps.

Made in China.

Love these escs
5/5 stars

Love these ESCs. Discussed blheli_s escs with Ryan from miniquad test bench, neither of us can tell any difference between blheli_s escs in flight (I have 6 different kinds), the spedix are a very good build and the best price. The 25amp version is working well with returner R4 2206 2300 and Armattan Oomph motors.

This is the second set of theses ESCs I have purchased, which should tell you everything.

I have tried plenty of different esc over the years, and I have to say these are some of the best.
