Building Lithium Batteries ? Which Spot Welder is For You?

Re-uploaded without music HERE https://youtu.be/JQoNBRrjsdo?si=9jmaOFRsoBQsbvcH

Nice video EXCEPT for the music which was annoying!

Man you guys are on point. It seems like every time I have a question about how to build my e bike build, your videos are the best and most in depth. Non biased, straight forward information. Just keep doing what your doing and you'll help more people than you know.

Please consider posting the video without the background music, as the music is very annoying to me snd possibly others.

Great review! - I'm a 75 yr old guy planning a 48v battery build for my converted Specialized stump jumper that I'm going to use on Vancouver Island this summer - I already bought the AwithZ unit and although it did a good job on the included nickel plated steel, after watching your review I tried it out with some 1.5 pure nickel and it didn't stick very well. Thinking I should return it and get something else. Thanks guys!

You know what I liked best about this video? Those 2 batteries being built looked very familiar!😅

this ... music. That's why I have blood in my ears now! 😫

Sweet! Wish there was a video like this years ago... Thanks, man!

Thanks for taking the time to review the various types of welders and helping those considering a welder to gain some knowledge into the various options. That said IMHHO the welders should not just stick the strip to the battery. An OK weld will be take moderate effort to pull off with pliers, a proper weld will tear out sections of the strip. To me acceptable of most pack construction and Somewhere in the middle is a weld that (on tear off) is causing a decent amount of material transfer from the strip....IE the weld although not penetrating the strip fully causing tear out of small sections of the strip, it will melt enough of the strip to cause a substantial depression in the strip and corresponding deposition of nickel onto the battery terminal. This is the minimum I would consider acceptable for two reasons. One is that anything with less weld penetration and area will be transferring the current through a small area (when in use) and this will generate a lot of localized heating that over time will fatigue the weld and can cause it to separate. The second issue is even if this is in a very low current draw pack (say a true 250-350w e bike) the vibration of the cells in the pack encountered over bumps can also cause fracture of the welds.

I’m getting ready to remake a small battery pack (6 cells) and you answered a ton of questions that I had, now I know that the small self contained welder will work fine for what I’m going to need it for, thanks.

Keep up the work, this video was very helpful

This was the video I was waiting for, Thanks. Liked the honest and surprise reaction to how well the capacitor welder worked. You will still build my E-bike battery packs, but I have smaller 12v -18v packs to repair. Thank again

Thanks for the review. You helped me much.❤

Hey, a useful video. Thank you for it!

This is great, great information! I live off grid and can't supply the AC current peaks that plug in bench mount welders draw, and the handheld cell powered welders really don't have enough power, as we saw. I was about to spend the big bucks on the Kweld kit , (about $400 cad to my door) but the capacitor unit you showed worked well and will sip power from my solar setup. Such real and useful material is like gold. Thank you.

I returned the AwithZ unit and bought the purple unit with a small car battery. excellent results.

Great video keep up 🌱

Great video definitely like the k welder the best because it is adjustable and can possibly also do other thin metels Thanks for the great videos always learn alot

Great information for a newbie like me.....I am amazed at the technology ...but still think I will buy from legitimate seller. Looks like it will be time consuming to build a big battery. Glad I subscribed! Always trying to learn something and your Channel helps make that possible!!

Thank you. I wish that you wouldn't put the music in your videos or at least mute it when there's narration, but I still appreciate the comparison.
