Looking for anyone’s advice on the optimum Vesc settings for my build. I am running two Racestar 5065 200kv motors (max current: 46A), two flipsky vescs (4.12, 50A continuous / 240A peak), a 10s3P battery and an Evolve AT kit.
I just wanted some opinions on vesc setup. Here is what I got so far:
Settings (per vesc)
Motor Max: 40A
Motor Min: -40A
Battery Max: 30A
Battery Min:-10A
Are these good settings? I just don’t want to fry anything.
We would need to know the specs of your battery. 30A battery max on both vescs makes a total of 60A battery max, so you need to make sure that your battery pack can supply that amount of amps.
Unfortunately I do not know. It was a freebie I got from alien power systems after I fried my last one (I’d solder the xt connector the wrong way round). I think it was a spare old one that APS had lying around. There is no info on it.
I think on all my boards I use 60/-60 motors and I have decent brakes. I would rather stress my pack, motors and components than not be able to stop when I need to. Just be aware you are doing it and give the board time to recover when you go over the limits.
How could you know this? What if the battery is a 10s2p 30Q battery? That can only put out 30-40a total. If he goes full out and has 50A battery max on both vescs, that will not end well pushing the batteries so far over the limit.
Sorry, I am finding this a little confusing Are we saying that the following settings are good?
Per vesc:
Motor Max: 30A (or change to 60A)
Motor Min: -12A (or change to -60A)
Neither setting will blow the Vesc’s or the battery, but 60/-60 will perform better. However it will stress the system and possibly fry a vesc (but not the battery)?
Battery Max: 30A
Battery Min: -10A
32v cut off start, 29v cut off end.
As long as these setting are adhered to the battery should be safe?
yes I recommend to keep your battery max at 30a for now and increase your motor max to 60a. if you keep the motor max at 30a you may find you are somewhat lacking in acceleration. later on you could increase the motor max up to 80a or even 120a, while retaining the 30a battery limit.
Do you know if I could run this setup in FOC, or would that potentially brick the Vesc’s?
The reason I ask is that one of the motors sporadically judders quite violently when running it in BLCD.
The motors have sensor cables which I could connect to the Vesc’s, however I’ve read that they can be unreliable and it’s safer to leave them unconnected.
