Hello there… im building a mountainboard using the torqueboards vesc (x4) and implementing a 6374 motor at 190kv on 12s… there will be two vesc off of each length of positive and negative power wires that go to the front and rear of the board.
My power wires are undoubtfully going to be long and i have read in many places that i will need to add capacitors across the leads near the vesc to help make up for the battery cable length.
My question is… is there a rule of thumb to follow for how many capacitors to add per length of battery wire? My battery will be going through a pcb a switch or two and then battery wire then be vesc… should i be counting my diy pcb as battery wires? Im assuming so. Can i use one capacitor bsnk for the length of wire that power both vesc? Or do i need to double it since there are 2 vesc pulling power through the same wire?? My electrical experience is telling me no but i figured id ask anyway…
If i may ask while i am here as well. My 190kv motors on 12s will come close the the erpm limit… what is the actual limit? And is there a way to set the erpm limit so i do not exceed it?
Thank you all much!
