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 ...

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

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...

Re: How good is Cyclone 4kw coaxial suspension bike?

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. My Luna Shark pack would be foolishly weak for a 4kW bike. But it's as easy to live with as the battery on ...

Re: new cyclone 3000 w mid-drive kit?

Since my QS205 is eating way too much battery My QS205 got great Wh / mile if I rode easy at a slower speed. If you're used to that motor you'll want too much from a Cyclone. The motor has about 200 watts of waste energy just spinning the gears in the upper RPM on 18S so it's not necessarily that e...

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

Thanks for all of the feedback. I currently build three drives that will fit the Qulbix frames. #1- Two stage bottom bracket drive. #2- One stage bottom bracket drive. There are advantages and disadvantages to each one. The two stage drive is best for steep climbing, pedaling with the motor, extend...

Just buy a Stealth Bike/Qulbix/Vector bike and save some headache... my opinion. Also 8000 watt is serious power, my 3kw bike reaches already 40mph+ and im also a 220 pound guy. Depending the battery; i would go with a 72 V and 40 amp. are you truly getting 40-45 mph top speed on flat land with you...
