Hi kntzn thanks,
You mean 90A max is a burst peak? Because from the setup from @Pecos was 100A per motor (which you instruct the VESC to provide). Is that continuous? I guess not, otherwise the connectors would melt…
4.5mm seem fine from your description then… it is the one used from the motor itself it would make sense
Don’t get too hung up on ratings for burst, the testing done by flipsky and some others isn’t reliable. I like to assume i can run most esc at 80% of their claimed continuous voltage and amperage and it may not die. Flipsky is especially famous for overstating their specs also. Many boneyards full of flupskys used at or under spec.
Motors are dumb, volts go in - amps go in, speed comes out - heat comes out. Within reason you can exceed the amp rating on the motors if you can keep an eye on heat. Simplified: the bigger the motor the more it can do before overheating - you just don’t have enough constraints on what you’re doing to more than guess and speculate yet. Just be somewhat near the continuous ratings to start. Test and adjust. Eskate loads are notoriously variable - try it and adjust. This is also (one reason) why diy isn’t cheaper than prebuilt often, gotta buy twice sometimes.
You ca kinda use other people’s settings and parts as a good starting point - just know it’s no t a rule that what works for me/works for you. Too many uncontrollable variables. Experience will shoot you in the right direction. Duct tape it all in place and test ride it
Thanks Pecos! Yes you are right, my ocd was making me try to have everything set im in my head before even starting. I will build and adjust. I think thanks to all of you I have all of what I need to be in the ballpark and don’t cause fires! So I will just start and iterate, adjust and get experience!
