Is that 20A per motor? Else that’s gotta be a bit of a yikes. Also was reading up on vesc guides and they save to have your vesc current limit 5% above max motor current. In such case how would that work here?
For example going uphill the motors will try pull more current then the vesc will allow. The website implied this would fry the vesc but that doesn’t make sense.
This project has already landed me an internship for my enginnering degree, safe to say the ROI is good on it as well.

no that’s a 20A battery max. you can give the motors more current for a more punchy feel. I’d say ~35A motor (half that per side) and 20A battery max could give you half decent results.
wow, congratulations! I hope esk8 can further my life in a way like that!

Battery current is not the same as phase current.
I wouldn’t push past 20A to 30A on the prismatic CGT battery. That’s battery total. So 10A to 15A per motor controller. But that’s battery current.
Depending on what motors you use, the phase current will likely be much higher than that. If you’re using the Racerstar 5065 motors that the CGT shipped with then that’s probably worst case scenario and those I think can do 55A-ish for the phase current. Per motor. They do get hot though so watch for that.

On a CGT, at this age, I’d be surprised if it could handle even those draws. They seem to really die off after a very short use life.

I agree 100% and this is why I’d use the lowest possible battery current that will work. 20A max (for both sides combined, so 10A+10A) is what I would probably do.

40A and it’ll sag like shit
