I could not detect any resistance with those connections. No fault lights with the phase wires connected either. Only fault lights when a hall sensor is connected to the VESC A. Both motors produce this fault when the sensor wire is connected to VESC A and both motors produce no fault lighy when the sensor wire is connected to VESC B.

Also I should say… with sensor wires disconnected, FOC detection spins up BOTH motors

#1114

Oh, then the solution is simple. Don’t connect the sensor wires :rofl:

Fair enough. I kick start anyways. Just disappointed. My DIY is not perfect… :cry:

As asked here:

What’s the power consumption of the ubox turned off but connected to battery?

Damn, so you can never use A.S.S

I remembered it’s less than 2mA, some guy asked in this thread before. I didn’t measure it now.

Any news about the voltage value problem ?

#1121

Fixed by flashing proper firmware, unless you’re referring to a different voltage value problem.

#1122

Which FW did you use ?
I’m indead taking about the voltage difference between VESC and BMS.

It is located on the product page for the Ubox:

I measured both stock and customed 5.2 firmware, the stock firmware in ubox has much more tolerance, but customed firmware shows little tollerance(0.7% tolerance). What’s your BMS? See measurement picture and video.

very strange indead.
I have LLT smart BMS.
I’ll try to flash again.

Isn’t it an off the shelf Lingyi remote with custom internals? Granted I haven’t been able to find CAD of that one to make a cover, but it’s possible he might not actually have it either.

I have Spintend horn and U2 Laser gun light and want to connect more things to control with a remote light button (rear lights, maybe some LED strips), however the plug is only 3 amps on the controller. How should I implement some kind of additional converter, relay or something, so it could be switched via controller and I could have more amps to play with? :grin: Horn would still be connected directly to the controller.

Building in Fluxmotion so have some space to spare.

Yes. Mosfet. You send 12v esc signal minimal amps through the gate and it will act as on/off switch for battery connection wire to lights.
