E-flite® 40-Amp Pro Switch-Mode BEC Brushless ESC (V2) is a high-quality sensorless brushless electronic speed control with an integrated switch-mode BEC that is very lightweight and efficient. It can operate without the need for a separate receiver battery to power your servos and receivers, saving you weight and complication.

Key Features:

  • Up to 40 amps continuous current with proper air flow and 55 amps burst current (15 seconds)
  • 5A continuous current, 5V Switch-Mode BEC Circuit (Proper cooling and airflow required)
  • Stronger BEC for support of most 3-axis stabilization systems
  • Drive up to 7 analog or 6 digital standard-sized servos with the BEC
  • 3- to 6-cell Li-Po, 9- to 18-cell Ni-MH/Ni-Cd input voltage
  • Finned heat sinks
  • Programmable motor braking
  • Safe power-arm mode prevents accidental starts
  • Programmable low voltage cutoff with settings for 3-cell Li-Po (9V), 4-cell Li-Po (12V), 5-cell Li-Po (15V), 6-cell Li-Po (18V) or 70% of battery starting voltage
  • Programmable throttle input range
  • Programmable soft start for helis and airplanes
  • Auto motor shut down if signal is lost or there is interference
  • Programmable timing—5 user-selectable ranges to use with a large variety of brushless motors
  • Utilizes new smaller Mosfet technology to minimize weight
  • Radio System Power ON /OFF Switch
  • Prewired connectors—E-flite EC3™ connector on battery input and 3.5mm gold bullet connectors on motor output leads

Specifications:

  • Continuous Maximum Current: 40A (Proper cooling and airflow required)
  • Input Voltage: 3–6S Li-Po or 9–18 Ni-MH/Ni-Cd
  • Input Connector Types: 13 AWG with E-flite EC3 Connector
  • Output Connector Types: 13 AWG with 3.5mm Gold Bullet Connectors
  • Momentary Peak Current: 55A (15 sec) (Proper cooling and airflow required)
