No I built this pack and it is bypassed for discharge.

Have all the problems been FOC?
Or 12s? 10char
12s is the problem.
This is what flipsky typed back.
Yes, we have received the same problems from our customers these days. So we have done some tests and found that the 4.20 works normally with 10S battery. Therefore, before we figure out a solution, we would like to suggest that you run the board with 10S battery.
Sorry for your inconvenience.
Default firmware is 3.40 and it was set to FOC too.

Here comes lack of capacitance to provide that quick extra power needed for that tap down acceleration

Well I guess I’ll be running my BLDC on 12s which is fine with me. I’ll use this VESC until I receive my unity.
Do you think bigger caps would solve it for 12s use?
Perhaps I could try that if it does.
Make sure you order LOW ESR caps but extra capacitance doesn’t hurt in my opinion.
wow how do you embed metr telemetry data like this?
Just paste the url in and let the magic happen.
Here is another short test on 30amps. I didn’t have any drv8302 error this time.
I will try a longer ride next time on the same settings. I think this one is safe.
But “over voltage” two times
So is this cutout thing a common issue for all 4.12’s, or it’s only limited to this FS dual vesc?
I havent had any cut outs or heard anyone else have on any other vesc…

This cutout problem is new to the FS 4.12.
I was talking about overall reliability/stability. The 4.12 overall is not stable (even vedder has admitted this) and breaks under certain conditions (generally speaking, 12s FOC). Vedder increased reliability with the vesc 6. For under $250, you could have 2x 6.6’s so while yes, a bit more money, it’s a completely different beast when it comes to dealing with heat also…

Is there any current group buys that will ship to Canada?
the US group buy can / should ship to canada at slightly higher shipping prices.
@Hummie has the order been put in?
i wanna use these on my next build…
They’re in the mail.
I’ll do another group buy for these tomorrow and do Canada too. It’ll be quick and there’s a lot of people who want them so will send it in in like a day or two. 6.6s as well

Exactly, they run really well on 10s even in FOC no cut outs on the 2 ive tested so far.

Will they be the single or dual or both?
