Clear, concise, no hype presentation. It enhances the credibility of the reviewer, giving the viewer confidence in the accuracy of the review thus helping buying decisions. Well done
I just ordered a radmission1, and found your channel and already showing me how to modify the bike. Keep up the great work
I bought one or these after watching the videos thinking I wouldn’t need to buy another one. After waiting 3 weeks with no tracking details I got it and it worked good for the first 35 welds, after that it didn’t even went to boot up anymore. Said my battery was low even being charged for 4 hours. No power going to the leads. Spoke to the company and they sent me a defective board to replace and that took 2 weeks to come. Then accused me of wrongful install when I shouldn’t have to install a product that shouldn’t be broken. After I checked out the 2 boards I realized that the new board had 2 clips soldered wrong and it was shorting out of welder. All in all I’m pretty done with sequre as they really don’t understand that customers are the ones that make the company, not the other way around.
Nice! I never spot-welded before and this looks like a perfect, nice size equipment to buy for beginners to use without difficulty.
Did you get it? How well does it work? Does it still work the same and have you had repair it yet?
I've been looking at pre-built batteries for awhile but they're either junk or too expensive. So I've decided to make my own and this spot welder seems to be the perfect tool! Doesn't break the bank and does professional quality welds, win, win! Nice review btw. :)
Glad I could help!
I use the one from Malectrics with a car battery, while charging the car batery with a floating charger. It works like a charm. Both based on arduino.
Thanks for the update on the spot welder. I have been holding back but this may make me buy.
bought the same one, love it... use it with a 12V AGM Marine battery, works like a charm.
I'm glad I'm not the only one that says little prayer before hooking up a lithium battery. Excellent video and product review! I have some electric projects planned and this spot welder seems like a good tool for beginners like me.
For sure, it takes very little time and effort - and seems worth it just in case it helps!
@@EbikeSchool Yes, it does help 😁 Thank you for your feedback!
Looks like a great way to motivate me to move along on building batteries. Thanks Micah!
Very nice demo, thanks for that. I like how small it is.
Loving the content. Looking to convert my mountain bike and building and electric trike based on a mountain bike rear for heading to my hunting spots on backroads this fall.
Im new to your channel and im amazed to your informative DYI guide for building a ebike. I hope i got some of your book. More power and more tut to come.
I also think it looks like a Malectrics. Would be nice to see a tear down. Also, IMPORTANT, you should not weld at, or too near the center of the neg end of the cell, as that is where the internal connection is.
You should get Malectric... This is POS. Not worth buying and if you want to return when you see welds are NOTHING but a tack and DO NOT BUILD BATTERY REQUIRING .2M NICKLE AND EXPECT SAFE RESULT.
i'm still newbie in diy Lithium Battery. This one is a good tool for diy... hello from Malaysia.
Rebuilding 32v 14 Ah battery, Secure spot welder looks very useful, loving the vids
Awesome. I’ve been looking for something well made and solid like this. There are a lot of crappy spot welders out there. I just ordered 1. Thanks for the discount
How has it been treating you?
Hey. I think finding a way to be able to keep the separate welders with one hand (maybe 3d print something to keep them together but in appropriate distance) would be very nice.
Thank you for the review... it looks like a great spot welder to build DIY batteries.
I like the small package of this unit, would be easily portable to allow for in the field repairs, as opposed to the large shop units that require you to get your repair project into the shop to work on them.
What an awesome welder, Micah! I didn’t know that you could do this at home in TelAviv!
This is a nice welder... Finally we got some competition to K-Weld. I hope the prices will go down so I can get one for mobile jobs. Thanks for showing!
This looks really cool! I might just get one to start making bike batteries myself.
The hand held trigger is a welding machine in itself. I have seen them being sold separately as handy welding machines at some places online. You just have to plug it in 12 to 24 v power source, they say.
This video was helpful in informing me about spot welding. Thank you
Very impressive unit... definately the way to go when building reliable battery packs, but it would be nice if the tips of the probes were a little bigger, less welds could cover more surface area than having to do many smaller ones.
Love this welder, thanks Micah
Thank you for the video. It would be nice if you took it apart to see the internal construction and quality.
I like it, adding it to the list of equipment I need to repair my spare 48v 21ah battery pack.
Thanks for the review , good looking effective piece of gear
The spring loaded probes maybe you can install it in one of those inexpensive presses for hand-drills.
I need a spot welder, thanks for vid Micah!
Thats a cool spot welding machine, small and solid
Stumbled on your channel, great video. I ordered via your link, saved $6.39. Thank you! Subscribed!
This is really close to a pro unit.I wonder how many welds it will do continuously before overheating.also does it have a fuse,for protection? thanks for the video.
Nice little welder, great review.
Great video! I am looking into getting a spot welder, good timing :)
Looks good. Time to see what's inside.
Thanks Micah for the comprehensive video. Your channels provide a lot of good info! Any recommendations for sources or specific motors to power a large motorcycle? Thanks!
I normally work with more bicycle-sized power levels, but I'd recommend checking out QS Motor.
@@EbikeSchool thanks for the recommendation! They have a wide variety of motors to choose! I am working out the design now.
Hope you're feeling better after your ammonia and your big move..
You probably got sick from your move,, I know I went to Russia and Siberia to adopt my daughter..
But when I got home I than had a temperature of 104 for over a month when I got back..
And I never been sick a day of my life..
I've been so lost with finding a good spot welder thanks!
Always useful Micah. Do you know where I could buy a bicycle frame that is already split so that I can build my own e-bike/bike using Gates belt ?
Thanks thus looks like a great product!
Love your tech reviews!
10:23 so much current cables are moving
Wow, nice catch! Magnetism is cool
Electrostriction and magnetostriction are cool. Can be hard on fuses as well.
Thanks, should be useful when I start my own build.
i really liked this video, it was very satisfying to watch
I’ll have one on the way soon !
Hello Micah. I love all the DIY info you provide in your videos. I downloaded the Kindle version of your "DIY Lithium Batteries: ..." There are no illustrations in the downloaded version? Did Kindle forget to add them or is they just not included in the E-version" I assume that there are illustrations in the hard copy. Thank you. Dave Isaacson
Awesome build. How many of those 36v batteries would I need to power a 36v golf cart?
I might have to actually buy that spot welder. As it looks both compact and convenient to use. only question is, can it weld more then batteries?
Looking at the kits, the foot pedal seems the way to go. Looks like you have to push hard enough to slip off the tabs on that push one.
Looks like something I might be interested in. TYVM for the Video.
Loved this one, I need this thing.
Nice Battery Welder. I would love to learn how i can make my own 18650 or 26650 Battery for my E-Bike.
Perhaps exchange the button-head *Phillips* for button-head *Allen?* There are drivers for those which are not merely-ball-ended, but also power-drive and setup like screwdrivers. (I have these in Bondhus brand, both metric and SAE…)
Thanks for an informative video, much appreciated.
Like the new tool. Stay safe.
Hi Micah, thanks for the review. Can you explain the Short Pulse setting? The default is 12% and range 0-100%.
Looks like great welder
Awesome saw this earlier now got Micah doing a review sweet!
If u had a choice of spot welder comparison in your opinion would you choose the sq-sw1 or the maleltric
A little high in price but looks like it puts really nice solid welds. Bottom line, is it better than the SUNKKO 788H or similar spot welders?
What do you think of all the handheld spot welders on AliExpress? The ones with a built in battery for $30-$50? Most of them say they can weld up to .15mm-.2mm nickel. Do you have any experience with them?
Looks handy for DIY enthusiastic battery pack builders 👍🏾 great channel, keep up the good reviews.
Really comes across like a very good welder. Will wait for the price to drop. Thank you
Nice and small one. Thank u mike.
Great looking welder
thanks for the review
that is good high quality welds unlike what is used by the hoverboard scooter batteries.
if you can pull the welds apart easily then they are not good welds
if you strip out the philips screws then you are done because stripped screws are difficult to remove
you may want to practice on dead cells so you dont have to grind off good cells
if you are going to welding a lot you will need a battery that can handle very high burst currents because seeing how the battery leads twitched when you welded you are probably drawing hundreds of amps in bursts.
Love your stuff man!
Very easy and portable machine, interesting
nice video! can you use a power supply instead of the LiPo battery to power this spot welder?
Will this make a re weld strong enough to hold a handle to a 2 quart Revere sauce pan?
Thanks to you , i make a purchase for this spot welder
What your problem with Phillips heads? Seems more practical since everyone has phillips head screw drivers laying around.
You did a very professional job nice voice also l believe you sold me on this one
Thanks for that review!!!
I am soldering as you are demonstrating. I will add this to my wish list.
I was doing the same😂😂 good luck
What else besides battery making would a spot welder be good for? Is it only for electronics?
I have a 2021 Bolton Lancer and I’m having trouble getting a secondary battery for it, seems it’s always out of stock. I’ve just purchased your book on DIY lithium battery. I’m not sure it will do me any good in build a battery for the Lancer as the secondary battery Bolton/Area 13 sells for the Lancer has a proprietary plug the plugs into the side of the Lancer. Do you have any thoughts on this?
Have you tried welding copper strip with this and how do you compare this to a kweld?
how about connecting d 18650-ies with magnets? like flat ones, 25x10x3mm for example? big question: could they damage or discharge d cells? maybe not as permanent solution, but at least for testing, when trying out different configs it would be practical. i may have seen it somewhere on d web. but, is it safe for d cells?
Hey Micah! How's it go with welding nickel strip to nickel plated aluminium?
Would love to see a follow-up on this product. Have you built any packs with it yet?
I second this!
What kind of batteries are them and what do you use them for ?
diy lithium batteries please! also can you make a video talking about voltage sag and how to mitigate it?
More packs in parallel is the first thing that comes to mind...
I think most camera have a feature so the shutter effect disappear or many just some tuning? 🤷🏼♂️🤔
Funny how you turn left to increase time 🙂
Love your videos. Thanks.
im a newbie 'Im getting one'. .....thank u great review
Another high quality video.
Thanks for vidéo , need to purshase one similar , IS it from Aliexpress?
I would like to make a bike which Hub drive or belt/chain drive which is good waiting for your replay
How long do you think it will take for 18650 batteries to be available again? Most sellers that I have seen are sold out for most types.
Hey Micah! Are you not selling your vruzend battery kits anymore?
I like this unit, portable to my radio control airplane events. Thamks
So you need a battery to make a battery?
Which came first, the chicken or the egg?
Looks like a Malectrics spot welder in a nicer case.
my thoughts exactly
interesting
Agree. I find it odd that he does not mention anything about that.
Very similar interface but pricy (£161 basic kit) got the Malectrics!
It should be verified if the manufacturer indeed copied the design and if yes, has he got permission to do that from malectrics?
really good review! I bought an el cheapo chinese one that I haven't used yet. Maybe I should just try to find the coin for this one.
BTW - I just bought the same batteries as you show here. :) Do you like them? the specs look awesome.
Nice spot welder!
