KISS ESC 2-5S 25A 4in1 (40A limit) - 32bit brushless Motor Ctrl
by Flyduino

The KISS 25A ESC 4 in 1 is one of the latest members of the KISS family and powered by M4 32-bit microprocessors. It is made with the main circuit boards from 4 of the 25A singles for a very innovative solution to a 4 in 1 and makes sure the reliability of the ESC is maintained throughout. Built in safety features such as total active current limit at 160A (4 at 40A) makes sure you have power without worrying about overamping the ESCs. Available as a 4 in 1 or singles HERE. 

Features

• No additional capacitor needed for up to 5S.
• Very fast throttle response, Linear throttle response, Active freewheeling (low diode losses)
• Regenerative braking
• 100-2400, Oneshot42, Oneshot125 and (25 - 500 Hz) PWM get autodetected.
• Supports FrSky Sbus, Graupner SumD, TBS CROSSFIRE and Multiplex SRXL, S-Port, Graupner HOTT, TBS CROSSFIRE and Sensorbus
