Thatâs what Iâm looking for! Iâve been dying to ride it
I have no idea but I assume this person VESC swapped also.
Note about VESC swapping SBX is that the Plastic Caster Bases / SR360 slip ring covers have 3.5mm bullets coming out. Same size as MR60. So if you wanted a drop in controller you could use many that come with MR60 MT60. Wires would be too short for a dual but two singles is ok.

Thatâs super legit! Still learning about all of the components and parts so that I know what Iâm doing & dont end up back right where Iâm at

The blu/wht wires?
I donât remember talking about them or BMS comms before.
Those wires seem to go to whatever I have circled in redâŚpower button? Covered charge port?

I have a perfectly good battery that Iâm not using that I could sell.

no sorry I confused you. That pic is showing someone add wires to the esc input to power lights. What I meant was these 4 pins from the battery to the controller.
Exact opposite of what I remembered. 
says right here data over those 4 pins⌠unless by data they mean analog temp data.
I donât see why the SBX ESC units I have should have a short on the main power input due to lacking BMS.

Could be. Could also be digitized voltage and/or current data but then why four pins?
Everything depends on where those four data pins go. If they go to an MCU they could be digital or analog. But if they go to op-amps or filters then itâll be analog data of some type.
Couldnât it be a failed component?
There appears to be a suppression diode there that could be shorted or it could be a different component.

How much do you want for it? Assuming youâd be willing to ship?
This is 100% what has happened. I think Iâve mentioned it earlier on in the thread.
There is a TVS diode on the ESC which blows when you plug a faulty battery into the board, then when summerboard send you a new battery and you plug that in you blow the new battery because of the dead short across the diode. This is why so many people complained about dead replacement batteries

I looked into those 4 pins when I had the board open and 2 of them are for the power switch. When those are shorted the battery turns on. The other two were some sort of digital comms. I didnt look into them much since it wasnt important at the time but my guess is the communication is either for battery health/status info from the BMS or control of the LEDs in the logo.

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 wasnât the issue with the board I bought.

Update: New battery came in and it turns out that isnât 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. DONâT 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 Iâd 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 thatâs 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.
