/diy/ - Do It Yourself

There may be other places to get parts i guess. Maybe there are some good 3D printed battery cases or knockoffs from China?

Is anyone able to just take 2 battery packs from 2 different companies and 3D print adapters?

>pic unrelated. Card full. No more screenshots. Ffs

You could buy the whole chink knockoff packs with chink cells for like the same money as your pic.

You gotta get in with the recyclers and scoop some packs, or warranty department at Home Depot (they can’t just trash old packs because muh dangerous lithium). Maybe a pawn shop could find you dead packs on trade ins, but those cunts would probably charge you nearly retail because they’re jews.

Or look for clearance or sale packs. 2pks or 4pks of 1.5Ah packs for some brands were going super cheap as everybody upgraded to better 2000mAh and 3000mAh cells in their basic 5-cell battery packs, but then you would be ripping apart perfectly good battery packs.

Yes, me. Pic related. Imgur albums of it:

I see. I'm fine with stripping new packs. I'll label and hord them for later. Maybe i want a 12ah drill from a 2ah case one day kek.

>>1766618
Wow anon... that's some next level shit bro!

>>1768012
Only problem with this, if you want to use it on high demand tools, the 1.5Ah packs and 5.0Ah packs probably have a different BMS. A lot of the newer packs will supply more power to bigger tools than the old ones and I’m guessing the BMS has some sort of limiting in there so you don’t kill the cells, and a 1.5Ah BMS, even with 12.0Ah worth of cells won’t power a full size saw as well as a 5.0 XR pack, it will be less powerful but last a long time.

>>1766470
I've built Makita batteries from chink kits and cells, and also have a direct adapter for some Ryobi gardening tools. If you can get good quality cells on the cheap, it's not a bad idea, but fucking with bad used cells isn't worth it. Chinese cells are cheap and so-so work, but under heavy loads they are noticeably worse performing than the original Makita. These chink cell packs are good for drills, sanders and such, not so good for angle grinders, recip tools, chainsaws, anything high amp.
Aliexpress tends to be the cheapest for these shells, and you can also buy the shell only, without electronics, for a lower price, if you just want an adapter.

>>1768334
Right on.

I've already been studying this. I'm a dumbass so i don't know. But i know you are right. Trying to find appropriate china made "brains" for them

>>1768344
Nice.

I actually found

why not just buy quality tools i never have the problem of running out of batteries and i work that shit all day

just buy red and forget about it

>>1768900
This would be great advice if you’re a non-poorfag. I made the impulse decision to buy into the ridgid line two christmases ago when Home Depot had their little “buy this set get this stuff free” sales. Now I’m about $800 deep into the ridgid line, counting my 4 batteries and 6 cordless brushless tools. I wish I would’ve gone with Milwaukee or Dewalt because they have cordless bandsaws. If I could safely adapt one of my ridgid batteries to a dewalt or Milwaukee bandsaw, I’d be a happy camper.

>>1768904
You could always get the corded bandsaw...

I wish Ridgid would do a big impact wrench. Can’t step on Milwaukee’s sales though.

Have you googled for adapters? Find a nerd with a 3d printer to make a few for you.

>>1768909
>You could always get the corded bandsaw...
Not really worth it considering we got the corded Milwaukee bandsaw on the work truck (it belongs to the contractor/shop)...but it weighs about 8-9 pounds and I have to find a place to plug in.

I’ve been using that one handed sawzall I was shitposting about all holiday season but I need to find the right blades for it if I want to use it to accurately cut 3/4”-1” EMT conduit...it’s come in handy great for cutting 7/8” unistrut though

>>1768911
I found the reverse one, there must be the one you need

I design and 3d print my own on a 100€ printer, a bunch of the adapters i make are for obscure brands of nail guns and other industrial tools. I would definitely recommend making your own because you cant always buy what you need.

>>1769543
How do you retain the batteries? They usually have some spring-loaded mechanism in the authentic ones and it seems like it'd be a pain in the ass to 3D print. Just make them tight enough to hold?

>>1769566
Ive recently started experimenting with actual spring designs but all the fully working adapters ive made have just been held in by a bendy part of the print. It works well enough, but sometimes it takes some wiggling to get them off the tool.

>>1769566
And as for holding the battery on the adapter, i just have an appropriately sized indentation where it should be.

>>1769543
you can buy an adapter now from almost any popular brand to almost any other popular brand, as well as very inexpensive adapters that can be mated to anything.

>>1766470
>Has anyone else modified powertool batteries or repaired them?

yes I made a thread about this about a month ago and was soundly told to fuck off.

I built skil to makita.

>>1769799
stout to makita

>>1769802
Here's one that converts makita battery to anything.

>>1769798
>you can buy
And they often charge a good $50-$100 for them. Now chinks are starting to roll out cheaper ones, but you can't get every type, and they're still comparatively very overpriced.

>>1769798
There now Chinese knock of power tools that work with many major brand batteries.

>>1769804
incorrect they are very cheap now.
dewalt tool to makita battery is $17.19

milwaukee to makita $17.84

universal adapter for a makita battery is $15.69

plus you can modify the USB chargers that connect to a manufacturers battery to anything you want.

>>1769809
I, too, can search eBay, evidently better than you can. $17 for a shitty piece of plastic with a two tiny pieces of nickel in it is overpriced. $12 for an even smaller piece of plastic that converts your battery to nothing is even more overpriced. These things should be like $5 and China would still turn a profit.

>>1769811
those prices are half of what they were just 6 months ago. when people were selling 3d printed ones for 2 to 4 times the prices they are now.

also seriously you're so poor that a ridiculously inexpensive adapter that cost $18 is too much money? You really don't understand how inexpensive they are selling these for. begone with you small minded person. also I didn't search ebay those are prices I paid for them.

>>1769811
Ah the old tactic of "I will down play something that's already out there because it's now part of my small minded narrative".

You people have no Idea.

You can take a $14 usb charger that snaps on to any battery. remove the guts and then attach that to any other battery (after removing the guts) wiring the 2 together and voila Instant battery adapter.

macyver would be so disappointed in you.

>>1769803
>>1769799
But then we commented how that 2-wire Makita adapter won’t really work with any tool because a lot of them won’t run without connecting to a temp pin. Will probably work with basic compact drills, but not with the XR or Fuel SDS or 7-1/4” circ saw.

>>1768900
Because with a little work i can make them universal for many other projects that are battery bn intensive as well.

Pluse the Milwaukee grease gun and battery was $350

>>1768904
Shit like this is a big part of why I'm doing this. I bought a new craftsman skill saw and sawzall with faggot nickle batteries. They finally have the option of lithium now but I've instead decided to casually collect them from yardsales and friends.

I have rough guess 8 nickle chargers 12 craftsman nickle packs and 2-5 of every tool. Most of them lightly used or still brand new because people won't listen to me and take care of their packs.

So, i figured i may as well put in some work and got lithium

>>1769995
have you actually tried this? stop conjecturing.

Here bepis is. Reading my mind again.

Tbh i feel like it's the never ending saga. Proprietary shit or suck it. And if you do find a fix we will sue your ass for making profits.

I don't have the time, energy, or motivation but i say .stl the fucking world man.

PUBLIC SERVICE ANNOUNCEMENT:


This is where the shills come in now. There is a wretched new "niche" called "motorless generators" these pieces of shit are building giant battery packs to run 110v shit. It's cool. But so far in my studies i found NO SHIT more than 1 company dry fucking uneducated retards but even worst a FUCKING DISCHARGE LOAD

So basically these filthy cunts rewrap china 18650 or 21700 cells and essentially clone the look of cells 3 times the price and quality. Then they make the standard made up claims and 5 minutes after use the charge pack begins to discharge until dead, then charge until full, and continue. So they BARELY meet american shit standards. Then they lie so hard they can't get caught. Then they cycle cells till they are trash. Then they market an upgrade and it's just.... aweful.

>>1769543
Anon. I doubt we could ever make real money here but i do have a need for a few adapters similar to your pic. I could send you the actual parts i need.

If you are at all interested in some cash or trade or just some fun experimenting with this shit hit me up. Acornstu@gmail.com

>>1770412
I'd delete that post if I were you. also you can buy whatever from ebay.

>>1769798

WHERE ANON?

is there a dependable place where 9/10 at least half assed work?

>>1769799
I like you anon. An no. I gave up here. Fucking faggots trolls and faggot trolls along with moderators help have ahit this place up almost as bad as /b.

Make literally any OP thread. Under 40 posts and archived.

Damn.

He did it.

Anon, just FYI the pack is marked. The internals of this "adaptor" just jam a spade terminal into the 2 ends...

>>1769805
PROTIP:

BAUER FROM HF. USES SAMSUNG CELLS. SUB CONTRACTOR QUALITY BY JUST A BIT. 75% OF QUALITY AND BATTERY FOR HALF PRICE.

I have abused the fuck out of my bauer shit and my buddy who owns a company that buys 100 dewalt tools at a time switched. They get broken well before they max out their life with "who cares it aint mine fags."

>>1770418
dude..... wtf are you smoking?

>>1769817

Yes anon. But do you use slow blow wire like tesla? Do you use only the best quality 100% nickel strips? Do you have a spot welder costing 20 grand with insurance or a busted microwave transformer and copper wire?

>>1770414
It's a spam account anyway. But thanks for not being a faggot like 80%+ of diy is becoming

>>1770421
Yes

>>1770423
well since you did not read what I posted. the usb adapters do have nickel contacts, and the wire I use is 14awg the same size wire that you will find inside a dewalt battery or most cordless tools.

>>1770421
Basically you have a battery for a power tool.

The pack even labels the battery +, -, and bms pins.

This entire adaptor basically just clicks on top of your battery and jams a spade connector into the battery + and -.

They charge almost 20 bucks for something a bit of electrical tape and scrap wire can do

>>1770427
BUT HOW DO SPOT WELD THEM

YOU SURE 100% NOT NICKLE COATED

nvm.

Not trying to shit on your work but these rapists charge a premium buy hiring a team of engineers to make sure they don't start house fires while most of us spot weld in the spare bedroom

>>1770428
sure anon, and by your logic you're just a conglomeration of carbon and water with trace minerals. so why did your parents spend so much on you.

>>1770430
so took me a bit here, you think I am making battery packs? no I just make adapters to fit battery packs to tools (like you).

Although I do have a spot welder I built using a starter solenoid, timer relay board from ebay and a car battery. the electrodes I machined out of brass and copper nails. IT works pretty good, and can weld at least 1/16 inch metal.

I'm sure you have built a better one though.

>>1770224
See this >>1770229

Clicked thumbnails on the video for 2 seconds and I’m assuming it’s dude talking about how only the light worked on the tool because there was no connection to the temp pin, right?

On the DeWalt batteries, it measures resistance of the temp sensor between the + and T pins or some shit, but you can trick it with the proper resistor between those pins. It’s not difficult to trick them, but lots of the tools won’t run simply by hooking up 18V and GND.

>>1770224
Have you actually tried running just 2 power wires into a tool with a battery temp sensor?

>>1770437
>Clicked thumbnails on the video for 2 seconds and I’m assuming it’s dude talking about how only the light worked on the tool because there was no connection to the temp pin, right?
nope he shows it working then takes it apart show why it works.

also all 3 of those posts are me.

basically you refuse to accept that there are easy inexpensive adapters that work and do exactly what people need AND are more than safe enough to use.

>>1770437

>>1770437
>Have you actually tried running just 2 power wires into a tool with a battery temp sensor?
besides dewalt tools don't use a temp sensor they look for a voltage across a second set of pins which is very easy to deal with.

Niggas gotta read, I was trying to help one anon find an adapter, but commenting on the stupid Makita pack with 2 wires hanging off of it because you can’t just tie + and GND to any tool and have it work. You need an adapter for that brand that deals with the other shit, so might need 5 different adapters for your one Makita battery with 6 different tool brands, not a “One Size Fits All” solution

>>1770448
>You need an adapter for that brand that deals with the other shit,
yes anon and that is in ALL the adapters except the universal one.

>>1770829
Yes, the one I commented on, the shitty universal one that I said is shitty.

See >>1770448

Original post you got uppity about is still up there. Read it 6 or 7 more times and maybe you will realize I said exactly what you are trying to argue for.

>>1770828
Why am I going to watch a video about a proper adapter? I was talking about the shitty one with 2 wires and whatever alligator clips get jammed inside the bottom of any power tool.

Surprise! If something needs 3 connections to work, it probably won’t work right with only 2 of them!

And yet it will still be useful and for some reason this enrages you? It can be used to connect any tool that does not need some special sensing to work which is most of them.

you can keep using older tools with new battery packs. isn't that nifty. Don't you agree?
