you think those switch pins with blue/white wires need to be shorted for the ESC to work?
I have removed the Diodes that @Lee_Wright was talking about, one on either side of the esc. Still dead short.
Im not certain, but I dont believe any of the 4 pins are required for the ESC to turn on. Where are you measuring the short?
These two pins are always shorted to put the two 6S batteries in series. The other 2 are the main + - terminals of the ESC

I may take you up on that in a couple of weeks. Just got a new battery and that wasn’t the issue with the board I bought.

Update: New battery came in and it turns out that isn’t the issue with my board. The battery checks out when tested. Unable to power the board on & when the charger is plugged in the green light immediately turns off.

turns out the vx1 has some of the more horrible connectivity issues out of every remote I own. DON’T USE IT IF YOU LIVE IN A HEAVILY POPULATED AREA LIKE NYC!
Having the two independent vescs turned out to be a bad idea. I kept getting CAN related issues where one esc would stop being detected and I’d have to do a firmware reflash to fix it.
Swapped out the makerx and vx1 for a xenith and hoyt puck.
Added voltage gauge.
Another ride video.
up next a new battery!

getting closer to completion.
Got final battery 12s3p p42a. Now the range is so good that I get foot/leg fatigue before the battery runs out. Now all of the major problems are sorted out.
next updates.
I eventually plan to replace the stock motors as well with 5065 that’s the largest motor that will fit on the sr360. Ill have to do some grinding on the caster to get it to fit.
Install the tomiboi bindings.

So they uhh
Still run
You think the wider sbx wheel solves the ground clearance?
A lot of this scraping is actually because I was trying tricks and used those wacky diy 5-X trucks that let the board lean super hard. So I have a feeling with stock sbx you could get by pretty well.

Hi guys. Ive just got a second hand SBX and it looks like a failed firmware update has broken the motherboard somehow. Im a total noob but would rather sort something to make it more reliable than it is now. Whats my best options for simple ish upgrades?
Try seeing with summerboard will charge you for a motherboard refresh. That would be much easier then going diy. Once you go diy you have to change all the electronics with would be like 500 even with low end electronics esc+battery+battery. Don’t tell them you bought it second hand tho just say it stopped working after an update and see what they say. You may have to haggle with them alittle bit. But if it’s a firmware refresh then that doesn’t require any new parts so they are less likely to charge you for a new board.

Thanks for the advice. I’m chatting with their support, just want to get it sorted asap to be honest and could do without spending too much.

Speedemon does anyone sell a conversion kit to upgrade the SBX?
No.

More or less yes actually. Basically all the parts are available. If you put a little bit of effort in, common diy esk8 parts with the right connectors would be an easy plug and play experience.

I bought a replacement motherboard this past summer for $317 including shipping.
Then after that failed, I spent around $500 on DIY parts. I didn’t need any enclosure parts though, I have a 3d printer for stuff like that.
I recommend scrapping the stock esc, control and bms hardware, they caused me nothing but trouble.
admittedly, the board doesn’t run quite as well with the new components, but I also haven’t spent much time in VESC getting settings right, so I blame laziness for that.
Ultimately, even if the lower max performance can’t be fixed, the reliability is well worth it.
my vesc setup runs far better than stock. you probably need to switch the sensor type to HFI.

rebuilding my summerboard is my first experience with VESC and esk8 in general. Did you change out your motors? or does sensor refer to something else?
no I still have the stock motors.

I should have searched HFI for a couple minutes.
I will try that out the next time I open up my enclosure, which is a bit of a large task thanks to my inexperience building
