Specifications

The BL-Heli XSD 20A Speed controller is a replacement ESC for brushless weapons motors. A very detailed video on ESCs and how they work can be seen on Youtube here: https://youtu.be/OZNxbxL7cdc

Our BL-Heli XSD20A ESC can serve in a variety of areas, but it should generally be viewed as a replacement part or a standalone weapons controller for a combat robot.

  • Operates on BLHeli-S software
  • Supports DShot 600, DShot 300
  • Voltage: 11.1V – 14.8V
  • Current: 20A continuous
  • Current: 25A Burst
  • Size: 24 x 14 x 4.5mm (0.9 x 0.6 x 0.2in)
  • Weight: 9.0grams (0.3oz)
  • BLHeli-S firmware upgradable via signal wire (works with USB Linker for XM series)
  • No on-board BEC.  Must provide 5V to radio receiver via other ESCs or separate dedicated BEC.

A great wiring diagram, thanks to Georgia Tech’s RoboJackets Wiki can be found here: DiagramWiring diagram for ESCs driving wheel and weapons motors

Note that the BL-Heli XSD20A ESC would be used in this instance as the orange element in the wiring diagram:  as a controller to a brushless weapons motor.  All controllers are driven from the same battery, as you can see from the diagram.  This model doesn’t have a BEC (Battery Eliminator Circuit), which allows all elements to be run from a single battery.  Power to the receiver can be supplied by the motor ESCs or by a separate dedicated BEC circuit.


NOTE: This speed controller is forward only, and can be used to control weapons but NOT brushless drive motors.
