DIY: Make power tool battery adapter from EVA foam

[@daveb7999]

Thank you for this! EVA foam looks to be a very handy and useful material, I didn't realize it was this easy to form and use for all sorts of things.

[@roadrunner694]

What can this adapter be used for?

[@johnmalecha666]

I love how you made the ring terminals, that will come in handy some day.

[@hjeffwallace]

I was so glad I came across this video. Your other videos inspired me to build an Ebike powered by a couple of 24 volt Kobalt tool batteries. Yesterday, I hit some rough ground, and a battery holder split apart. I tied it together with a bungee cord. I usually ride about 20 smiles per hour.

[@maderightamerica3216]

I was looking for something to use as a mold for our new pedal assist electric vehicles. Your EVA Foam is exactly what I was looking for. Thanks for demonstrating how easy this foam is to work with.

[@DaveEtchells]

Great tip, I had no idea that EVA foam could be used like this; I just didn’t know about it as a material. Thanks!

[@krazmokramer]

VERY impressive video. Excellent explanation. I have no use for this at this time, but I know where to return to if I ever have the need for this adapter. THANK YOU for this great video!!

[@groundskeeper5292]

Amazing. Never thought of using eva foam. Have some scraps in the garage!

[@quickb16crx]

I legit laughed out loud starting at 4:50 into the video. Great content as usual!

[@HRTsAFyre]

Me too! That cracked me up.

[@smile768]

Great video. I think EVA foam is my new friend.

[@FleaMarketSocialist]

Holy shit I found my new favorite channel

[@mrmotofy]

Consider using a plastic called Kydex. Easy to heat and form

[@richardwellons5138]

Great approach. Additioally, I'd first smooth/round the contacts before installation, and use more EVA foam to mold a cover. 24 VDC shorted is quite exciting.

[@user-sf9mh1ms4q]

Very nice. I did mine with a "moldable plastic Thermoplastic beads", using press and seal or saran wrap to cover the battery. Then, just like molding a putty, you press it to all the necessry areas like the slide and lock. When it is almost cured but still workable (slightly white, I slide it off the battery and use scripto knife on the terminal holes to finish the slot all the way through. I dont even need to make holes on the battery lock (It locks in place). Fits like a globe. You can use a thicker material like aluminum foil to wrap the battery If you like it a little bit loose.

[@lupillos7404]

You make awesome vídeo another great video really like that Eva Foam 👍🏻

[@way2g619]

Awesome video I was trying figure out how to do this thanks

[@tysontyson1244]

You are brilliant! Thank you for demonstrating how to make a ring terminal!

[@sewasewa6585]

Very good idea, I will try it. But I would reinforce the back with an insulating hard heat resistant material like a piece of plywood or odd floor laminate piece with holes for the contact screws. High current with mechanical contacts have habit of getting very very warm. And a final cover also. Lithium batteries got bad reputation even though they getting much better now.

[@AC7812]

AMAZING AS USUAL!! THANKS

[@crumblenaut9776]

Excellent idea! Thank you

[@AB-C1]

Fantastic video mate! Well done! (Hope the integrity of the PVA foam hasn't been compromised too much by your screwing the screws so tight to flatten it?) You nigytbeb wise to add a couple of extra layers of foam one on top before the aluminium to make it thicker and then one op top of that above the screws so that they're isolated and not exposed (it also adds a bit of impact resistance to the top of the battery aswell as preventing shorts!) Aside from that good cheap and quick result! I might try this myself on some different batteries I have.. I wonder if you can make some battery adaptors in the same way? EG. To fit one tool brand to fit another brand of battery? Maybe you could try a video on this? Cheers from London England 👍😎🏴󠁧󠁢󠁥󠁮󠁧󠁿

EVA foam and a heatgun - nice one, thanks 😄 No need for a 3D printer 😉

[@mirriulahwaterdog]

Love your innovative work mate...

[@fixitkev1966]

Looking forward to more videos. Would love to see more ebike motor and controller content. I have an ebike testing meter. 0ne of the $15 variety things. When testing the controller I am getting a sequence of lights that tell me the controller is not working. Would like to know what the meter is detecting and how to troubleshoot or repair controller if possible.

[@stephensanchez5761]

Good video, can you do a video on a 40v Battery with Eva foam and connect it to a pure sin wave inverter? I have some Hart 40v battery's that I would like to use any good ideas?

[@vuaeco]

I did the Kobalt 40V adapter a while back. Here's the video: kzbin.info/www/bejne/iKi8oqZ-m7xne5Y

[@BarbeRodzTV]

Wow nice idea bro thank you for sharing this video 👌

[@billrimmer5596]

Good morning. What is the third terminal for?

[@vuaeco]

Third terminal is signal wire for the Kobalt tool. It runs from the battery BMS to the Kobalt tool. Without the third terminal, the Kobalt tool won't work. But since I'm making this for everything else but the Kobalt tool, third terminal is useless.

[@naturesmoments1297]

Great job, fist time I have come across EVA foam, is it the same stuff as gym mats and the like or are there special types for heat moulding, cheers ?

[@michaelflora375]

What was the size of the peace of foam. Please tell me in inches thank you. Great video

[@barismetin1014]

Where can I find the battery contact terminals? Thanks awesome Video!

[@andanh8]

You are genious! vuaeco.

[@flierbill]

Good stuff! I guess I could cover the terminals with hot glue or something like that?

[@vuaeco]

Yes, hot glue is best, for protecting the terminals from shorting out.

[@Sylvan_dB]

Or you could glue some additional pieces of foam to box in the terminals.

[@electronic7979]

Good idea

[@biggregg5]

What mil. Thickness of EVA foam did you use? I'm guessing Amazon was your source. Great stuff. Thorough....easy to understand. Thanks!

Ever thought about getting a 24volt inverter for power backup useing the tool batterys?

[@vuaeco]

I did that a few years back with 2 Milwaukee 18V power tool batteries. Here's the link: kzbin.info/www/bejne/bqvZgYB5gtufeMk

Hello sir , I hope all is well and staying dried I have so much thinking of how to make my own without a cnc 3D printer ? Thank you 🙏 so much !

I dunno about those exposed terminals, but that's otherwise pretty well done.

[@ulisesortiz3820]

I'm Mexican, eres un chingon 👍

[@Mike-fs4cj]

You're a f****** genius

[@jamest.5001]

It would probably be better to make the electrical connections with about , 12mm copper tubing, hammered flat, then filed or sanded to get more precisely flat to fit the battery, and bend and drill. Holes and possibly use copper pop rivets to attach, solder 12 gauge wire to the terminal, then attach to the battery, and coat the outside of the adapter with epoxy, if you want it to be a bit stronger!

[@mattisfahani6021]

I need DIY to get my Snapper XD/Victa work, it has no battery . Thanks

[@odgreen9113]

How thick is the foam?

[@catcherxuefeng8516]

can you make cordless Drill use type c with Power Banks work?

[@mwint1982]

Nice, just use something to cover the exposed terminals lol 💥

[@curiosity2314]

Great idea.

[@Shad0wSmurf]

How high was the temperature on your gun for that bending? Can't seem to make it bend as easily as you 🤔

[@РОССИЯ-д3л]

For what purpose is such an adapter made, what is it used for???

[@Carlo-qs3yn]

can I use an aluminum foil instead of the aluminum strip you used?

[@martinmuldoon603]

No don't use aluminium foil it's too thin and weak, try to find copper cuttings someplace, maybe a plumbers wasted cuttings. Copper is a better conductor.

[@RixtronixLAB]

Nice information, thanks :)

I'll marry you. Are you still desperate? LOL that was funny. Watching you make this adapter I must say. You are briiliant. Not sure if i can use this on my lawnmawer to convert it from 24V lead acid to lithium like you just made. If so it would be perfect.

Thank you!

Nice

[@r.hernandez6152]

At least your not making a bomb out of it!

[@SciDOCMBC]

It's not the smartest idea to heat a battery pack with lithium ion batteries with a heating gun. But the project itself is great. You should just remove the batteries before heating. The electrolyte in batteries is volatile and highly flammable.

[@HRTsAFyre]

The battery wasn't attached he only had the plastic piece

[@chodechotchney5331]

That trick to turn the wire into a ring was pretty slick. But I'm going to assume if someone doesn't have any ring connectors, they probably don't have a soldering iron. I don't know what kind of weirdo would have one without the other. You either have both or neither

[@wrathofsocrus]

I'm that weirdo, I despise crimp connectors. Way cheaper to keep scrap wire, solder, and an iron on hand than a complete load-out of crimp connectors. I did the same thing with heavier wire on an inverter with a 10mm head bolt and nylon locknut just like in the video. Taped a cheap 10mm wrench nearby because you can never have enough 10mm wrenches!

@@Vile_Entity_3545 Because I think vuaeco is a great KZbinr trying to help people with DIY projects and explains himself very well. Why would people come to these comments to discourage DIYers or vuaeco? If some people don't gravitate to this content then that's their problem. The function of the projects on this channel speaks volumes whether someone wants to listen or not. It's lovely that other people have other methods, but people would be surprised just how different some people live their lives, such as having a soldering iron and no ring crimp connectors on hand. I specifically rolled with it instead of being insulted because I don't want to be like other people purely to 'fit in'. There's a long line of people who know I'm a weirdo, and they all call me when their stuff breaks. I wear the weirdo badge with pride.
