DIY: Make power tool battery adapter from EVA foam

Make a Kobalt 24V battery adapter with XT60 connector from EVA foam. Wanna see how beautiful Eva is? Let's check this out!

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.

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.

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

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.

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!

[richardwellons]

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.

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

chinese companies should hire this guy. he is a legend 😁

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!!

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

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

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.

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

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?

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

[sewasewa]

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.

Holy shit I found my new favorite channel

[lupillos]

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

[quickbcrx]

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