Little FOCer! 84V 5kW VESC-Based Controller

They are not the same. There were changes to both the ESCs and the boxes to accommodate them.

Well thats not good. Actual battery voltage was 79.5V.
I forgot but I will lower the voltage max like you said before.

(This is on a Onewheel with poor construction causing odd behavior)

Did this happen during regen? Says that no current was being drawn at the time of the fault.

Not sure 100% but I think I was just riding around grass getting wheelslips and stuff. Riding quite mellow, I think it was more of an anomaly than a clear issue.

Shaman what’s the soonest the tronic 1000 going to be available?

Hello, @shaman I remember you saying a cap can be taken off to fit into tight spaces in a high inductance hub application (Onewheel). Just to make sure, is it still so for v3.1? And, for that matter, could two caps be taken off? (I should be fine with one)

Yeah you’re fine to do that with one cap for the OW application. Most have found that one is enough

Is it safe to drive a relay from the 5v output? I saw somewhere in this post that 500ma was okay and my relay draws about 80ma. I just hooked the signal and vcc wires from this relay: Inland Single 5V Relay Module for Arduino - Micro Center After the fact I realized the logic is pointless if I’m driving them both from the 5v. I just want to make sure no long term damage would occur from the relay.

This sounds fine to me. 80mA is well under the max output of the 5V rail.

Okay, thanks! I don’t understand back EMF or if that’s even a thing in this case. I just know relays can blow stuff up so I figured I’d better ask before blowing it up. :slight_smile:
