Not in the US you can't. The kWeld full kit from Grid Rewired is $246 plus shipping plus the ultracap module is another $195, kSupply kit is $125. Oh, if you want a housing for it that is another $26 and $29. So, $621 plus shipping and tax. That "AWithZ" 14-kilowatt unit that I linked above is...

Ahh I missed the fact that you are looking for something that can handle .3 nickel or nickel/steel. I suspect you'll have to move up to something like the kWeld or one of the more "professional" Capacitor based spot-welders. Such as this one from Seesii: https://a.co/d/h4v84XM Or this...

Starting off with the recommendation for a type (not necessarily the seller, I didn't buy from this one): 6.5V-16V 99 Gears Adjustable Spot Welder This has been the best I've tested so far. I am using with a 16AH SPIM08HP 3S pack. With that pack I have successfully welded .2 quality nickel...

I think the -10 is a brag about their low temp performance, not a required operating temp.

Well that explains a lot! I can’t believe I missed that during my digging. No worries on the VESC- I have plenty of use for it. At least I know what I’m dealing with now. I’m surprised it worked as well as it did before the observer falls behind.

Well breakthrough- I should have read that 5.03 thread better. Once I disabled Phase filters it fixed the issue and now throttle is much smoother without any backwards start. However motor and PID settings are requiring a lot of tweaking. My current motor settings that largely match what it...

That’s what I suspected but with how sloppy it looked I wasn’t for certain. Thanks for confirming. I switched to 5.03 but unfortunately if anything it made it worse. I have figured out that PID mode doesn’t seem to be properly functioning at all. At default settings after the FOC wizard it...

Great info, I’ll give that a go! The only concern I have on the GO-FOC is a messy solder job on one IC (buck converter). Several pins are bridged, but not sure if that’s actually an issue or intentional. The IC is a TI LM5161 PWR, spec sheet here: https://www.ti.com/lit/ds/symlink/lm5161.pdf...

Update: I picked up a GO-FOC HV200 VESC controller- I picked that up based on some analysis of available VESC units, the HV200 has a $ per Peak kW of $8.83, which is the cheapest by far for a >100 amp capable VESC. Well there is a 75v 300/450amp unit on Aliexpress, but no idea when I'd actually...

Oh and I totally agree that board isn’t going to ever work again. But I had come to that conclusion early on- I had no chance of hacking the interface and the only way to really learn about it’s guts was a total tear down. If I picked up another one of these I’d consider trying to utilize the...

You are spot on there- thanks for the reminder, I wondered about that when I was typing up the other post while waiting in line at the pharmacy. I just checked it and it’s a ADA 4571H. Which is a “High precision 180° angle sensor”. https://www.analog.com/en/products/ada4571.html I’m not...

The biggest thing I was hoping to find but haven’t is hall sensors. This appears to be a sensorless setup? I suppose it would rarely be starting from a dead stop with a significant torque load. Though it is used to start the ICE, for start/stop functionality. There are sensors at each phase...

Well the saga of tearing apart things I don’t fully understand continues. I have now taken it apart to bits and pieces. Let’s just say it does not disassemble easily, it drew blood, as is tradition. I’m sure someone out there that’s familiar with these things is raging at my terrible...

I took the wrong strategy for disassembling from the top. Ended up taking out the capacitor (ruined it) and then figured out I have to remove the back plate anyway. I have to separate each welded phase joint to safely remove it. I’ll post more photos once I do so. I decided to sleep on it...

Looks like those are 8 TOLT MOSFETs per phase. But 4 high side and 4 low side? I’m not familiar with that configuration. If you look at each phase set, there are 4 contact pairs coming from under the capacitor and with each the upper is positive and the lower is neg. So on closer inspection...
