12AWG should do fine under 90+% of use-cases.

[MysticalDork]

I don’t know of a software fix, and the underlying cause (BEMF going through the body diodes of the FETs) is pretty much unavoidable. I’d say just leave the esk8/vesc on while you kickpush, or physically disconnect the motor wires, or the drive belt.

Yep should be fine
But easier to solder 14awg if I would get away with it
If we are doing 70 motor amps how much would each phase take

[MysticalDork]

I’m not sure exactly how vesc tool’s motor current measurement is set up, but I would guess it’s using RMS current, which is 1/(√2) = ~0.707. The only way to know for sure is to actually take an amp meter and measure it though.

Anyone know this anti spark

makerx

[Halbj613]

You know if it’s any good

[frame]

personally have not use that one before, but u need a latching switch for that

“official” claim: 12s 100a

but u know how the math work

[Halbj613]

Thanks

Anyone know what is considered a reliable anti spark these days
Maybe 100 real amps

[tech.shit]

Whenever I ask this the main answer I get is “Amass XT90s”
And if it’s well over 100A then I guess Amass AS150

Reliable?

How about a loopkey for $10?

Fancy?

Now you’re talking about active electronics and added cost and maybe increased failure rates

Fancy?

[b264]

Yes I am a huge fan of that. It’s very well done.

I have a solution if u stay less than 18s, but it’s fucking massive

[Halbj613]

Let’s hear

biggest mofo

[ShutterShock]

300a tho dang lol

[b264]

Never fully trust numbers coming from folks who profit from sales

[b264]

Unless it’s a “number of motors” specification

[City-Blade-101]

True dat.
