Take care with your battery max setting.
If you run 80A for both escapes than all good and ignore my comment.
If you set 80a in every escape than please split it to 40a on each escape.
your battery can´t handle 160a and I guess the escape could fry over 60a too.
if he don´t plan to constant break a 3km hill he should be fine with
24A in total too. the break current appears usually just for some seconds.
the q30 should handle this.
I don´t think it´s true, but when I blow my first vesc the guy how sold me his 4.12 vesc said that my settings (dual -6A) on the vesc was too low and the break current resulted in heat up the drv…
If somebody can say if it´s right or just bullshit, it would be interesting for me
let´s say like this:
the breaking current depend not only from your bat min settings, also from your motor min setting. If to set the motor min to -45 and the bat min to -6A
the break energy need to go somewhere. that´s the -6a back to the battery and the rest into heat of the motor and maybe also the vesc somehow.
but this I don´t know. would like to know if the break energy also transform into the heating of the vesc?
the thing is, that I would assume that in my specific case the vesc should not blow, but shut down because of overheating. there was no overheating, so I don´t understand how it could cause the blown drv.
There isn’t really a set answer for that question. Consider how long you brake for, gradient, hills etc. If you’re not slamming on the brakes you might only be using half your regen max anyway. But anyway it’s a vesc pick the safe option first and you can always change it
Find out what the safe fast charge limit is for your battery and divide by 2 for dual Vescs.
Thats where you set the Battery Min.
The Motor Min can be higher.
I run my Motor Min at -40 and Battery Min at -12 for My Lipo build that is capable of 25a fast charge according to manufacturer.
