Issues with throttle range translating to duty

Submitted by Elliot Kingsley on Thu, 2025-10-16 02:40

So I recently purchased a fsesc flipsky 6.7 single esc version. I hooked it up to a hall effect sensor type pedal, a 6374 170kv brushless motor, and a 36v 12.8ah lithium ion battery. I downloaded the free version of the vesc tool on windows, set up the motor, and entered in the battery info. When that was finished, I hooked up the pedal, power to 3v pin, gnd to gnd pin, and signal pin to adc1.

Charging Li-ion battery using the VESC Harmony 32S BMS

Hello!

I connected 6 Li-ion cells, each of capacity 1200mAh and nominal voltage 3.7V, in series to form a battery. I connected this to a VESC Harmony 32S BMS unit and tried to charge it with SKYRC's iMAX B6AC V2 charger. The charger shows an error saying "Connect error...Check main port".

About How to control the "FLIPSKY Dual FSESC6.7 PLUS"

Submitted by tonyH on Tue, 2025-10-14 11:35

Hello everyone,

Im Tony, I am studying how to control the motor speed according to throttle input values.

So, I found the "FLIPSKY Dual FSESC6.7 PLUS" and I already download Vesc Tool latest version.

But I have some problems..

Situation.

1. To operate an inner motor with 8 poles, a FLIPSKY DUAL FSESC6.7 PLUS motor driver (model name VC-67D-S100) was used.

Custom-made VESC PCB: High current sensor offset/Overcurrent fault during motor detection, possible hardware/firmware mismatch

Submitted by Chinmay Mulgund on Mon, 2025-10-13 13:56

I am using a custom-made VESC PCB. When running motor detection, the motor makes unusual noise and the process fails with the following errors:

Detection failed. Reason:
Overcurrent fault, Check there are no shorts and ABS Overcurrent limit is sensible

and sometimes:

Detection failed. Reason:
High offset on current sensor 1, check for hardware failure

The same motor and wiring work perfectly with Maytech OEM VESCs, so the issue seems specific to the custom PCB.

Help - physical switch to change profiles on ADC15

Submitted by SwissCanuck on Sun, 2025-10-05 13:59

Hello

I need your help because I cant find a way to get this configured.

I fitted a physical switch to the ADC15 (unused) pin like the ADC2 (brakes), with 3.3v.
And now I want that switch to change the current profile used.
This would be like a low speed for children - high speed for adults.

I am unable to find the ADC15 in the app and to configure the function.

Maybe I am just too stupid

Cheers

Help Setup Flipsky FSESC 4.12

Submitted by R66 on Mon, 2025-09-29 05:23

Using the setup motors wizard went very straightforward.    Normal remote response. Like an idiot, after watching several videos, I did NOT realize the the flipsky VX1 remote is a UART connection and unfortunately , set up the ESC as a PPM ... 

 

My question is how do I re configure / re program the ESC to accept the factory UART  VX1?

 

 

2 Speed ADC control

Submitted by totalgeek9224 on Mon, 2025-09-22 19:47

Hi all,

Looking for a very specific scenario, where I want to be able to control the VESC output ia ADC in the following manner:
ADC1 HIGH & ADC 2 LOW: Max RPM
ADC 1 LOW & ADC 2 HIGH: % of Max RPM

Physically- there is no case where both ADC's can be high. 
How can I accomplish this?

Unstable current readings over VESC CAN (UART/USB are fine)

Submitted by vukstijepovic on Mon, 2025-09-15 16:59

Hi everyone,

I’m having an issue when trying to read current values from a VESC( 4.10) over CAN. I’m using an LPC microcontroller to monitor the CAN messages, and everything works well except for the current. The values jump around a lot and don’t look correct at all.
