Re: The BEST and FIRST Qulbix Raptor mid-drive build!

Ok so in this case the Option One Stage Big Block Drive seems better, if i don't want to buy a new Swing from Qulbix right?
But the parts except the Hub remains the same ? My goal is to realize the conversation around 1000$.

Re: The BEST and FIRST Qulbix Raptor mid-drive build!

Re: The BEST and FIRST Qulbix Raptor mid-drive build!

Perhaps a stupid question but how does the Sabvoton SVMC150 match with the L-R Swingarm Big Block Drive ?
Im thinking of getting L-R Swingarm Big Block Drive.

But after repalcing the Batteries and limiting the discharge to 20A instead of 40A it caused no problems. Overall im impr...

Re: kWeld - "Next level" DIY battery spot welder

I didn't get a manual, the only source is in the internet download page. Didn't see the Calibration sentence.

Re: kWeld - "Next level" DIY battery spot welder

Okay i found the problem. I had calibrated(shortcutted) through a nickel stripe which caused the problems. Maybe the inventor should put up the warning, so any other people shouldn't pay "learning Money" by making stupid mistakes like me. I have punctured about 10 cells. HbPowerwalls video helped me...

Re: kWeld - "Next level" DIY battery spot welder

Okay how should I say.. First there's a touch with some sparkles after that there's a good weld with nickel plate melting, but at the same time liquid is coming out. :? *edit* also twice a small flame came out. https://i.ibb.co/sqVjjyQ/IMG-20190609-121130.jpg https://i.ibb.co/sqVjjyQ/IMG-20190609-12...

Re: kWeld - "Next level" DIY battery spot welder

Yes but like i said 9,5 Joule after Calibration had enough power to burn.
Tomorrow i will do more welds with 2,5 joule on 0.15 mm Nickel. Besides that everything is fine.

Re: kWeld - "Next level" DIY battery spot welder

Is that normal that the K-Weld can burn through the Battery that Electrolyte comes out? Probably Not.

So has this happened to Someone else?

Re: kWeld - "Next level" DIY battery spot welder

Quick update I received my K-Weld after few welds liquid came out. First i thought this was Water from previous use but turned out it came from the "Lanzhd" Cell. I had the setting on 9.5 Joule automatic However i reduced up to 2.5 Joule and worked better. I measured the Cell voltage and still seem ...

How to best describe the difference :roll: I did multiple welds to 0.15mm nickel with sunko and prayed afterwards that even one of then would hold. With kweld every single one is constantly strong and I need pliers to rip off the nickel and it tears of around the weld points leaving the welds and r...

That weak Hailong battery looks so misplaced for 4kW.. im not sure what they have thought by doing that setup. Hailong makes cases, not cells. You don't know that the cells in there are weak.
