Unboxing & testing the Sequre spot welder for DIY batteries

[@HIROLLER9]

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

[@bulldozaaa9353]

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.

[@JohnS-sn2sd]

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.

[@paulnobody8050]

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.

[@BattleHawkHeavy]

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.

[@EbikeSchool]

For sure, it takes very little time and effort - and seems worth it just in case it helps!

[@BattleHawkHeavy]

@@EbikeSchool Yes, it does help 😁 Thank you for your feedback!

[@toddjago3265]

I just ordered a radmission1, and found your channel and already showing me how to modify the bike. Keep up the great work

[@edgelord6560]

10:23 so much current cables are moving

[@samuelseidel6148]

Wow, nice catch! Magnetism is cool

[@xeeded]

Electrostriction and magnetostriction are cool. Can be hard on fuses as well.

[@donfrommpls778]

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. :)

[@EbikeSchool]

Glad I could help!

[@andycapo9you]

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.

[@ChristianLuckins]

Looks like a Malectrics spot welder in a nicer case.

[@jaylord55]

my thoughts exactly

[@albaharh]

interesting

[@kkops]

Agree. I find it odd that he does not mention anything about that.

[@peteturner8493]

Very similar interface but pricy (£161 basic kit) got the Malectrics!

[@Arek_R.]

It should be verified if the manufacturer indeed copied the design and if yes, has he got permission to do that from malectrics?

[@bambatsa1310]

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.

[@EverythingEbikeChannel]

UI looks very similar to the malectrics spot welder

[@joepublic2894]

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.

[@captainyak3948]

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!

[@vernhartjr]

Awesome build. How many of those 36v batteries would I need to power a 36v golf cart?

[@dumsterdave]

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?

[@justinc8157]

What your problem with Phillips heads? Seems more practical since everyone has phillips head screw drivers laying around.

[@databanks]

Do they make mains powered versions? Preferably one that can handle both 120V and 240V (or just 240V for my requirements)

[@shimes424]

If they did it would be more expensive than using a battery setup. Spot welding needs a lot of DC current so storing it in a DC battery is cheaper and easier than using large enough caps and switching circuitry to use AC input power Although I've never spot welded before, but I suggest using a meady 12v 16ah LiFePO4 battery. Only $55 for 200Wh and it can do 500w continuous (40A) maybe more if you replace the internal BMS Lithium iron phosphate (LiFePO4) batteries can output so much more power without voltage drop. From what I've learned, voltage drop is usually what causes bad spot welds, so not powerful enough battery causes voltage drops, abd many things can cause that from battery type, size being too small, not enough charge on the battery, age, ect.

[@guywatkins]

Was I randomly chosen? That rectangular handle thing looks way to large and awkward. Did you notice the spot welds also left holes or dents in the table? Watch at 3:55

[@EbikeSchool]

yes the table is lacquered (I originally built it for the kitchen in our last apartment) and so I think it melted the lacquer a bit

[@joearcuri3377]

bought the same one, love it... use it with a 12V AGM Marine battery, works like a charm.

[@dennisyoung4631]

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…)

[@Bige4u]

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.

[@JosePerez-il5qy]

Thank you for the video. It would be nice if you took it apart to see the internal construction and quality.

[@KetansaCreatesArt]

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.

[@Progress303]

The spring loaded probes maybe you can install it in one of those inexpensive presses for hand-drills.

[@diamonddbw]

Looks like a great way to motivate me to move along on building batteries. Thanks Micah!

[@Danny_Elite]

Nice! I never spot-welded before and this looks like a perfect, nice size equipment to buy for beginners to use without difficulty.

[@triaxialwolf951wolfy3]

Did you get it? How well does it work? Does it still work the same and have you had repair it yet?

[@Dang_Near_Fed_Up]

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.

[@petercrawford5513]

[@dji-tesla-paragliding-ando9641]

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

Or can i use sand paper to remove the excess nickel weld?

[@amitzahirr]

Hey Micah! Are you not selling your vruzend battery kits anymore?

[@rubensosa384]

If u had a choice of spot welder comparison in your opinion would you choose the sq-sw1 or the maleltric

[@vxeel]

You mentioned that you will “clean up” your test spot welds later. What method do you use to clean them up? This could be useful information for us DIY used 18650 crowd.

[@vxeel]

@Ivan Goring what type of file? All the files I have are straight. How do you clean up the negative side without also damaging the battery sleeve?

[@StefanBacon]

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.

[@k4x4map46]

nice video! can you use a power supply instead of the LiPo battery to power this spot welder?

[@manski209]

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?

Hey Micah! How's it go with welding nickel strip to nickel plated aluminium?

[@GenderSkins]

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?

[@rokrjock33]

Isn't this the one with the built in battery?

[@bikeboomer2617]

Very nice demo, thanks for that. I like how small it is.

[@ejonesss]

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.

[@wembry432]

Will this make a re weld strong enough to hold a handle to a 2 quart Revere sauce pan?

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?

[@gilsthefish]

Curious what a battery made from Grown2's would do. I vape and the Life4 cells live up to their name. It is the only cell that can run my vape at a true 120 watts not to mention they will put out every bit of amperage you ask for till the are bone dead. They are pricy and I contacted the supplier to see about bulk orders of 200+ but no reply as of yet.

[@OldinMariner]

Thanks for the great videos, I was wondering with this spot welder how it will do with different thicknesses? I have been looking for a reasonable priced unit that will handle 0.15 or higher and maybe nickel plated copper up to 0.3. Thank you

[@SequreTech]

The pulse time can be adjusted by spot welding different thickness nickel strip. You can start with 5ms pulse time and slowly turn it up. Up to 500ms Find a suitable pulse time. Of course, the pulse time is also related to the discharge coefficient of the battery you use.

[@bulldozaaa9353]

This can be adjusted, but from experience mine went out after about a week. Remember that it’s going to take weeks to get warranty if you can even get warranty. I don’t recommend this spot welder for longevity. I took mine apart and it was poorly soldered and was pretty bad quality. If you can get your hands on a k-weld you should. Not this one speaking from a person that regrets their purchase

Mine is not working correctly, a 0.1mm strip needs about 30ms to 40ms and 0.2mm can't weld at 100ms and that's with a new battery(5000mA 3S 100c) I bought from Sequre!
