Review: Aikon AK32 4in1 35A ESC

The AK32 4in1 35A ESC is the latest 4-in-1 ESC from Aikon that runs BLHeli_32 firmware.

I am quite excited about this 4-in-1 about it’s one of the very few BLHeli_32 ESC’s that supports up to 6S LiPo batteries.

Note: The unit I reviewed here is a prototype of the latest version. The Spec is exactly the same as the existing model on the market, only with some small changes such as the added JST header and the location of the capacitors.

Unboxing

The Aikon AK32 35A 4in1 ESC only comes with a signal cable and no other accessories. Maybe an XT60 femail connect would be an nice addition?

Spec & Closer Look

  • Voltage Input: 2S-6S
  • Current Rating: 35A continuous, 45A burst
  • 5V, 2A BEC
  • Dimension: 36x36mm
  • Power wires: 14awg 10cm
  • Signal cable: 10cm, 10 wires, GND, GND, BAT, 5V, PWM4, 3, 2, 1, current sensor, TX ESC Telemetry
  • Weight: 20.4g with wires

It supports current sensor and ESC Telemetry which has become a standard in BLHeli_32 ESC.

Due to the beefy FET’s the board extended an extra 5mm to each side of the board, this could be a challenge for some compact frames.

Testing

I am using this ESC in a 6S build, and so far it’s been working great!

    How would you compare this one to the Holybro Tekko32 4in1 35A ESC in therms of performance and reliability for 6s setup ?

    Best, :)

    Ok, newb question. Can I connect the CURRENT wire from the AK32 to the current sens input on a Brain FPV Radix, which is 3.3V max or to the voltage sens input which is 35V max?

      I contacted Brain FPV and asked them that exact question. Response was that they couldn’t comment on the current scale when using the Aikon AK32 35A 4in1 ESC, they haven’t tested with that ESC. They did say that connecting the current sensor wire from the ESC to the Current Pad or Plug Wire of the Radix FC “Shouldn’t be a Problem”. However when I connected from the ESC to the FC, my current was reading 77 amps at idle… which of course was Waaaaaaay Wrong!! Perhaps Oscar could test this issue as he has both the Radix FC and the Aikon AK32 35A 4in1 and has also had several questions on this topic.

    They use PVC wires in the conector, please tell them to stop using that wires… We want 30AWG silicone wires.

    Two questions…

    1) Can the 5V BEC be used to drive anything?

    2) How can the telemetry from 4 motors be passed using one wire? I’m using the Matek F405 CTR and it has one telemetry pad for each ESC. Being that I am not using stand alone ESC’s, is telemetry even possible?

      1) You can use it to power your FC, or RX, VTX, Camera, LED etc if your FC doesn’t have a big enough 5V regulator.
      2) ESC telemetry is passed to the FC using a i2c protocol, the ESC telemetry data is sent to the FC with an unique ID header, and the FC can tell which ESC the data is coming from by checking this id. The same happens when you use individual ESC’s, you still have to connect all the ESC telemetry signals together to the same pin on the FC, the same is happening here.

    Man this ESC is sooooo close to what I want in a 4in1 – they just need to ditch the 5v reg and the single huge current shunt and stick 4x smaller shunts on there instead so the ESC current limiting / ESC current telemetry works correctly..

    I would replace the ESC’s on ALL my quads with them if they did this!

    Flew it few times with the Matek F7 board – really solid on BF 3.2.4
    Can’t wait for BF 3.3 to come out with stable 32Khz support
    Flashes iNav too, easily wires GPS + Compass, I2C pads are convenient and did not have to do any crazy resource remapping.
    This might be my new goto BF flight controller.

    I wonder it this is an new revision? I just picked up one and its different from your Pictures.
    the one I have is the same as the amazon link and similar to the graphic on the Aikon site.

      Yes it is. Same spec and feature as the existing version, just added the JST header and changed the layout a tiny bit.
