Vedder has actually designed this controller to be the same thickness and width as most 18650 packs. A pack large enough to power two of the controllers to their potential would be at least 130mm wide
As good heat dissipation is a major factor in the life expectancy of a capacitor it would actually be better to use 10 smaller caps in order to maximize surface area.
Theoretically that is.
Chances are the VESC will die before the caps do…
Good thing I will be able to resurrect them if that happens but the whole point of this version change was to make the VESC more robust when used with larger motors. The current version 4.12 is actually very stable with smaller 50mm motors.
Yes, they are designed to match the 18650 form factor. The power leads will be routed between the 2 capacitors, a much cleaner design. Keep in mind that these will come with an aluminum enclosure or at least a heat sink setup.
Can you update the software to drive yuneec motors? These motors have the hall effect sensors mounted on consecutive poles instead of 120degrees. See photo:
I’m curious if you have tried it without the sensors? have you tried to power it in BLDC mode? if ya did, howed it go? i know its a bit under powered but i got a couple spares at home from replacements and another VESC on the way might make a decent beater board.
I haven’t tried it because I don’t have a Vesc. Another user tried and couldn’t get the sensored functionality to work. The other user was able to get it to work unsensored and bumped the speed significantly.
I want a vesc but I want to make it work with the sensors if possible.
