I'm looking to use 18650 batteries to power my mountain board and can't figure out if I'll overload the VESC controller if the voltage varies. The voltage required is 22.2v - if I use batteries which can produce between 25v and 45 v does the controller handle the greater than needed voltage input ?
thanks for any help!
I had a strange fault on a makerx A200 after the hubmotor sheared the key and rotated the axle ½ a turn, shorting out the phase wires.
After fixing the motor it ran really poorly and having trouble starting the right way (sensorless) and often cogging like crazy. I checked phase outputs, gates, current sensors etc. with an oscilloscope and to my limited knowledge everything looked good or at least the same between phases.
Why my VESC TOOL did not have "balance"?
where can I find it?
thank you.
I am trying to repair a friend's dual motor Trampa mountain board.... He managed to trash the CAN and comm cables and ripped the power connector off the battery meter.
I don't know what if any damage he did to the actual electronics, although I don't see any obvious issues like burned / blown components...
So it's my understanding that, ideally, regen braking intensity should reduce or be entirely eliminated under several conditions, such as: batteries too cold temperature, batteries already full.
In these scenarios, it would make sense to actively brake by applying negative throttle and using battery power to reverse the motor against the natural flow.
Hi
I am new to use VESC and I know that the ppm input is used in VESC. As my RC receiver is CPPM which is not support by VESC, I hope to use PWM as input for VESC. Can I write a cutomer app for PWM input? and how to configure PWM pin and c code for it?
Thanks in advance.
My VESC 6 produces 0.8 Hz current oscillation on level ground with FOC at max speed. I've tweaked the Observer Gain from the default 17.8 to 9 and 35. I think 35 was worse, but 9 didn't fix it and I feel like I'm tapping in the dark. Maybe someone has seen this behavior and knows the cure? Also, oscillation feels stronger when the battery is full (41 V) vs. 37 V.

Hi, does anyone know what the best way to configure VESC to control a e-bike descending on long steep downhill slope? (without activating the braking) i.e. the controller hold is a constant speed. Appreciate any help.
When you think you resolved one issue, another one is waiting for you around the corner. :)
Hi guys i am currently repairing a flipsky vesc 6.6. The owner of the vesc could not solder to save himself and ended up burning the swd pads off the pcb trying to reflash firmware with stlink utility. This would never have worked anyway as i found the mcu was shorted. Im about to resolder a new stm32f405 onto the board so i want to make sure i get this right as there is no way to reprogram once its back on.
