measure the resistance of the motors and the 3 phases.
Only the side with the receiver works at any given point, if i swap the receiver over, that side will work
Help pls.
When I run motor detection one side spins up but has zero torque . Ie I can stop it with my hand. When I swap the motors round the same thing happens so they’re not the problem.
Any help very much appreciated as it’s making me think one side of the vesc is faulty. Thx
Re-run detection, and remember to keep the remote off while doing it. If that doesn’t help try running detection and programming it off the opposite side.
@OzzysPaw Thx . Tried that but still the same issue. Both motors work fine on one side of the vesc. How do u mean programming off the other side? These are the results from motor detection
If you are on a pc plug into the opposite USB port and Re-run detection… If you are on bt plug the bt into the opposite side and Re-run.
Gotcha. Thx
My ubox randomly stopped working after 3 years and I don’t know why. I don’t see any damage. I see some lights then hear a constant high pitched sound when I connect it to my battery. I have not altered the firmware.

Yours stopped working all of a sudden with no clear cause? It also fried my davega connected over uart. Did you have that too?
Was he able to fix it for you? Do you know how the problem was identified and what caused it?
turned the board on one night, left it one while i changed a wheel. the boards lights were still on and stuff went to use the board and nothing happened. after alot of trouble shooting jaykup i sent it to him to have a look and both MCUs had died.
firmware update a couple hours before hand, it ran perfectly fine when i tested it but just stopped when i went to use it again

Help pls
Having motor issues
if it is set port config to UART to vesc A , then the motor for vesc B has zero torque
If it is set to UART to Vesc B then the motor for Vesc A has zero torque??
Hello @John-Spintend @AmySpintend
Is this a good HW 0.6 version. or are there already newer versions? If so, can you buy one from them as an upgrade? The negative battery cable is soldered really badly, so I would like to remove the lower circuit board. But it seems to me to be glued with silicone. Can I expand this somehow by heating it?

Can someone help me find the data sheet for the transiystors. I’m still looking for a way to solder an additional 2.5mm2 wire at the rear positive line.
By the way, you should put washers under the two small screws in the middle. Otherwise the mainboard will bend or it can start to vibrate. In my opinion, the guide pads are far too soft. I’m thinking about gluing it together at the end.

- the white glue can’t be heated to melt.
- we don’t suggest you to solder any wire on the negative battery cable, there is copper bar to transfer heat very quick, it would be challeging for you to solder it well. Please please consider my suggestion!!! suggest you add cable in battery negative wire directly if you have to do .
- Be cautious to add any washer under screw. the scerw size is decided by design file.
- there is no new version of this model, it’s stopped production, have no idea where should we can buy for upgrade . we’re the original manufacturer. The upgraded version is our new model to replace it .

3.ok i think is better withe loctite fore this screws.
4. ok
1.Which transistors should be installed there in the 100v V2 X2 version black. ?
2.How thick are the power lines on the circuit board? It’s not understandable to me that only the minus has an additional copper line. How many amps can go through without any problems without unsoldering the transceivers? 150 amp battery. equal to 75 amps per motor?
3.There is no way to connect a temperature sensor. then use software to throttle the Vesc, for example to 50 battery amps?
hi everyone, i have some issue related to firm 6.0 so want to go back to 5.3 and l need firmware :
