As my battery can only deliver 180a max i went down with the absolute max amps to 100 per esc

no seems like they are going to send me a half a UBOX for less than half the price.

Said the 100V dual is what uncle John is hardworking on.

Hello guys i have another question regarding my ubox
Im running a16s5p setup which has 67,2v fully charged
The smart bms and the multi confirm this value (measured right before the ubox)
But the ubox sends wrong volts to my davega and my xmatic app
The volts from the ubox are too high by 3v
So the fully chared battery is at 73,2v
Do you have any ideas what can cause this?

Are you running the custom firmware?

im running the 75/300_R2

You have to run the firmware from the Spintend site.

It’s mislabeled in the software last I checked, it was labeled as 75/300. But the Trampa 75/300 was also labeled as 75/300. So no way to tell by that alone.

Did you get it from the Spintend site?

sure thx very much for looking into his

That is the wrong firmware and is dangerous.

Load a “custom file” from the Spintend site.

They accidentally named their firmware the same as the Trampa 75/300 so this is an easy mistake to make. The Spintend engineers need to come up with their own name for #define HW_NAME and not reuse the 75_300_R2 name. Something like UBOX_75_100 would work much better.

Is it possible to setup the spintend only using the vesc mobule app?

In the firmware section, which ‘hardware’



option should I select?

Do I have to hit ‘UPLOAD’ after I make my selections for hardware and firmware?

so i tried to uplaod the custom FW from the spintend site but after the upload is done i still have the 300_r2 on my escs
what am i missing?


i tried it to upload it to all ecsc and to one after the other but nthg changes

I’m talking out of my arse here because I have no experience, only recalling conversations i have read.

The firmware may not be updating properly because the bootloader may be fucked.

You may need to do SWD shit to get your shit to work good

Then you should be able to upload the custom firmware

Please do. And please do not ride the board if you are getting the wrong voltage reading through the ESC. It can be catastrophic.
