Still some V2.1 units available! Lead time 1-2weeks. Supplied without a heatsink as we have run out and cannot get anymore soon due to virus issue in china.


Quick tips on setup

Max battery cable length without additional capacitors is 1m (Battery wires should be short, thick and grouped together, motor wires should be long)

Please be careful when programming settings. Start at low currents and work up. Setting everything at max during initial setup is a bad idea.

We recommend detecting motors using the FOC motor setup wizard. This will automatically find the correct settings for your motor. 

If you experience ABS overcurrent faults a lot, then increase your switching speed to 60KHz. Turning on high current sampling mode is not a good solution as you are only masking the root of the problem.


High voltage LiPo is extremely dangerous if handled incorrectly.

ALWAYS run with a fuse. We recommend a 150A or lower fuse.


Current Handling

100A continuous with no additional cooling

200A continuous with additional cooling



 Mechanical Features

  • Weight ~350g
  • Battery connection wire length: 10cm 
  • 6061-T6 CNC Machined Aluminium Heatsink anodised black

Electrical Connections

Power/Motor Connections

  • Triple XT60 input connections  (Maximum battery current is set to 180A on the input. So below 90% duty cycle you can use full 200A output current)
  • M5 Terminals for motor connection

Logic connections

  • Motor connector - Hall sensors, encoder, temperature
  • Communications connector - ADC, UART, SPI, Buttons
  • CANBus connector
  • PPM/Servo connector
  • Integrated 0.5A 5V BEC
  • Optional - 12V 2.3A BEC (on Fan controller board)

Motor Commutation Modes

  • FOC - Sensorless, Hall Sensors or Encoder
  • BLDC - Sensorless, Hall Sensors or Encoder
  • DC - For driving brushed DC motors on outputs A and C. (Can also be used as a current source or voltage source)

Motor Control Modes

  • Current - Controls current to motor irrespective of duty cycle
  • Duty Cycle - Controls duty cycle sent to motor irrespective of current
  • PID RPM control - Controls motor RPM using a PID loop

Control Interfaces

  • PPM
  • ADC - For use with analogue throttles, supports cruise control and reverse
  • UART - For PC control using VESC®* Tool and custom applications
  • CANBus - For custom applications, also supports slaving controllers and traction control

Voltage Rating

  • 0-75v INCLUDING VOLTAGE SPIKES, 16 cell LiPo maximum (recommended 14S max)

Current capability 

  • At 12S and below you can use full current capability
  • At 16S we recommend setting motor current below 150A, and battery current below 100A.

Safety Features
