    You really need to have a fuse in-line close to the battery, as these batteries can easily put out enough current to melt wires that thick. (The Makita 18V packs are internally protected by two 50 amp fuses in parallel!)
    Also, be aware that most lithium tool packs don't have internal over-discharge/undervoltage protection, as this is usually done by the motor controller in the tool, so connecting to random loads could trash the battery if left to discharge too low,

      While most batteries don't have over discharge protection every one I have ever opened does have a fuseable link basically just a super thin one inch trace that is basically a 30-60 amp fuse and I have blown them they work even the off brand China replacements I have opened have them. and on better brands like Makita Milwaukee and dewalt they have actual fuses or fuseable resistors

      That's strange, my Ridgid batteries are great for this, protection is in the battery, I assumed this was standard. It has to be on at least TTI brand tools - Ryobi, Ridgid, Milwaukee, and AEG. The batteries are pretty much the same inside. Always shuts off at 15v, 3v per cell, perfect! Overcurrent protection too.
      Most of these batteries are meant to be backwards compatible for old NiCD tools, obviously they never came with onboard protection, so protection *has* to be in the battery.
      I do like to include a self resetting 30A breaker in adapters like this anyway, like $5.

One way to safely use Dewalt packs is to make a connector using an OEM Dewalt battery adapter designed to allow use of Lion on their older NiCad tools, which has protection circuit built in (only dewalt oem ; the cheap aftermarket adapters have no protection).

    Nice one! As a teenager (like 15 years ago) I played with power tool batteries to power all kinds of things, like PC speakers and connect them to an MP3 player for use on the go with friends. I speculated with ideas and designs how to properly connect to the battery without repurposing a power tool. 3D printing made this so much easier.
    Your design is so neat. And all that in under six minutes. No BS, just the facts and how it was done.

    Thanks for these Clive; a nice simple solution, and really useful for me as I have a load of those Parkside battery packs. Thing to note: The Lidl/Parkside packs don't have any over discharge protection, as it is in the tools and not the battery pack. So if you use this with the Parkside batteries, make sure you add an over discharge circuit, or be careful not to let them get too low.

    • @tomaskolinger
      @tomaskolinger 2 года назад +17

      To be more accurate - the battery does have protection sensing but doesn't have power mosfets for cutoff. Protection is thus split between the battery and the tool.
      When battery gets low, the battery sends "alarm" signal over temperature connection to signal the tool to cutoff. External protection will not be ideal since you don't see all cell voltages (only battery does) and thus if one cell is lower than others external protection may cause damage/early failure.
      To properly use Parkside 20V batteries you need to replicate what the tool does. Battery has 10K? (guessed value) NTC resistor across third "temperature" pin and GND pin - in normal state but if any alarm condition occurs (like cell undervoltage) battery disconnects NTC and thus creates voltage resulting in invalid temperature (around -20C) and this signals the tool to cutoff. The tool has pull up resistor on third pin creating voltage divider together with what battery has as pull down resistor, when battery signals alarm then third pin has around 4.5V with 10K pullup to 5V. Perhaps there is 100K? parallel resistor across NTC, this would explain why alarm isn't 5V when NTC is disconnected (100K pull down is always connected). Thus proper protection wound need to monitor third temperature pin with pull up and when voltage gets very high on the temperature pin then mosfets or relay need to be disconnected (for example if divider equates to >=4V with 10K pull up to 5V).

    In the US Ridgid batteries are without question the best for this sort of thing. They come with a lifetime warranty, which they honor with no headaches. Make a phone call and you get a new battery within a week! We all know batteries will die of old age at some point, but they still replace 8 year old batteries just 'cause they got old. No other brand will do this. They are hoping you will forget after 8 years but I keep that number handy! ;) They have very high quality Sony cells inside.
    They also have all the protection/control circuitry inside the battery, not the tool, as apparently others have. I have bought a bunch of battery connectors from china-bay, I use these to power so many random things. Before 3D printers I just used some alligator clips...
    I am disappointed to find they discontinued the big brick 9AH battery...good thing I got a 6 pack with the warranty. :) I don't think they offer this on AEG batteries outside the US, even though they are the same thing.

    A note in re suggestions to glue more than one part together: Some of the common 3D printing materials, notably PLA and the ABS family, are attacked by acetone such that they can be solvent-welded with it. Just moisten each face with a brush, and press them together for a moment (and then wait for the solvent to migrate out of course). Seems to make quite a robust joint.

    Love it. :) Mod tip. first power: Angle spades 90 degress , remove the plastick cover on the spade, and solder it directly to an XT60(XT90 placed in the middle if your adapter with the opening facing the same way your wires are exiting today... solder spades to XT60/XT90. Hotmelt it down and you have an solid mass in the middle with an great XT60/90 outlet.
    Ryobi mod idea: Same principle, Angle spade 90 degrees sideways facing the straight side of the battery. Add another jacket with an XT69/90 connector that slides over the adapter you made, where you put the XT connector facing up from the battery. It will again give you an great and solid outlet for differet outlets. The new jacket might also be an USB 2/4 way module integrated into this new jacket. :)
    Love your design so far tho. Great start :) Thank you :)

    For those who are interested in getting a usable voltage/current from one of these batteries and be able to provide over-discharge protection. There is this DC to DC converter that they sell on Ebay called a "Dual headed synchronous boost-buck converter." It's based on the Linear Technologies LTC3780 controller chip. I don't know if I can post a Ebay link. But if you go to Ebay and do a search for "ltc3780 buck boost converter" it should be the first item on the list. The one you want should have 5 silver electrolytic capacitor and a torroidail inductor with 2 heatsinks on each side. It will also have 3 blue colored trimmer pots as well. It should cost somewhere between $15 and $20. The reason you want this particular one is because it has an adjustable under voltage cutoff that can be use to protect your battery from being over-discharged. Plus, the thing is damn efficient. about 97% if you run it at about a %50 load.

      @@tin2001 Yup pretty much. I suspect that it works well between 15 to 20 volts. Probably even a bit higher but without taking it apart and inspecting the circuit I wouldn't chance on higher voltages. The low end voltage is based on the guess that it probably works as long as the voltage is a few volts over the battery. I should test if it has some under voltage lockout circuit some day. (The battery packs have that which is good though).

    I have something similar for my Ryobi batteries, I use them as field charging batteries for R/C planes and drones. Ryobi batteries are especially convenient, because they have an internal low voltage disconnect while most if not all others put that inside the tool. This is probably so they can be put inside older tools meant for nicad packs. It also simplifies and thus reduces the cost of the bare tools in many cases, further feeding the "printer and ink" model of power tools and batteries.

I found an ideal unit by Harbor Freight (20 volt) but, of course, you must use their own battery. I am not a fan of different battery types so I looked in eBay and found a guy who prints adapters so I can use my regular DW batteries in the Harbor Freight tools.

    Since, like most things these days, products are only made by about 4 different factories then manufacturers slap their brands all over it, meaning quite a few batteries are actually compatible with each other or only need minor modifications to the case to allow them to fit, so it's worth searching along the lines "are Ryobi 18v compatible / interchangeable?"
    For example, I have a Greenworks mower and I found an article from smartfamilymoney about battery compatibility, it was quite nice of them to do all the work for me figuring out that several batteries from Kobalt, Snapper, Powerworks, etc were all the same and thus I found some Snapper batteries sold as "not working" for just $20, they only needed to be brought up to 3v per cell, so the charger would recognize them and have worked great.

    Here's another use for the 18-20V tool batteries that may not be something many would think of: using them as a temporary power pack for laptops, via their AC Adapter port.
    Most laptops are 19V DC input from their adapter, but can still operate from a range of voltage. Having perused forums, the consensus was that using 1V higher is going to be within their tolerance spec same won't harm anything (personally, I've always wondered if the circuits used 24V DC rated components since that's a common voltage).
    Of course, running at a lower voltage is doable, but I lack an adjustable bench PSU to actually test what the lowest voltage is it'd operate on. I wouldn't be surprised if it was fine down to 16V, as long as the battery could put out the needed current (given that pretty much everything in a laptop is sub-12V, and probably 5V these days; sans battery).
    Of course, an inline fuse would be smart. Hell, even for Clive's for that matter 🥴
    [CAVEAT: Some laptops, on their power input, handshake with the adapter to ensure its an authorized unit (ie properly specced), and if it isn't then it runs/charges at a very reduced rate, like trickle charge rates. Smartphones do, or did, similar, as all of us have no doubt experienced at some point this past decade. Point being that the same 'problem' would happen on those laptops by using a battery, since it wouldn't recognize the source.]

    There's no overdischarge protection !
    Well actually there is but it only works when the battery is used to power a Dewalt tool, in this case it will automatically shut down when the battery is discharged, but hopefully before it goes so low that it will sustain damage.
    I'm pretty sure it's because the battery communicates with the tool and Dewalt batteries do in fact come with 5 pins instead of 4 for the Parkside ones. (Although my Dewalt drill does only have four pins, but the charger comes with all 5).
    One of them is used by the charger to monitor the battery pack temperature and also the tools won't power from a bench power supply or anything else that doesn't come with the data pins.

    Couple of remarks: the designs on thingiverse often have the goal to be a wall mount for the batt or be part of an adapter, so you want that clip-in action altough it rarely snuggly fits.
    Adapters are to be done with caution, as some makers have the battery protection in the tool (Dewalt, Makita) and some have it in the battery (Most others I think). But generally the adapters and mods I do are my middle finger to the tool makers and their battery pricing. You can grid away a plastic rib in the parkside 12V and use it in einhell 12V (common here too).
    I am working on an adapter that is very compact an uses folded copper sheet or can be made from pipes to use my dewalt batts in all the chinese Makita-Knock offs.

    I'm just curious about what project you want to do with the batteries. Also, I've seen the connectors ready made for makita, bosch, milwaukee, ryobi, etc on aliexpress

      It was inspired by the Pinecil soldering iron. It also has programmable low voltage cut-off.

    Generally, it's a good idea to use the "horizontal expansion of the initial layer" setting in your slicer (assuming your slicer has such a feature) to make the first layer a little smaller. That way, you don't have the elephant's foot in the first place. Alternatively, you can either chamfer the bottom of your parts or make the first 0.2 mm (or whatever your layer height is) a little smaller, in the 3D model itself.

      I've seen some people design a small chamfer into the part where it will be in contact with the print bed to counteract "elephant's foot"

    Very nice! I'd be using much thicker conductors though unless it was fused down. Those battery packs DON'T hold back when it comes to kicking out current!

    thanks Clive, finally a use for my dead parkside vibration-cutting wiggly noisy thing, i will chop off the connector and make something useful :)

    On the Ryobi, you could extend the perimeter walls a few millimeters and then fill in with black hot glue. It would look really nice.

    Finland has that same x20V Lidl. And the Ryobi of course. I have a lot of Makita tools and batteries. I just bought the Ryobi cordless sliding mitre saw and ordered a makita-ryobi adapter so I can use my makita batteries in the ryobi saw. Works great

      Does your battery adapter have protection against low discharge voltage? Because Ryobi has that function in the battery and not in their tools, thus if Makita has that function in the tool rather than in the battery your combination could drain the battery below the safe level for low discharge voltage (because neither tool nor battery include the needed protection).

      @@stevebabiak6997 no, it only has the two connectors. I'm using a few older batteries for the adapter. I also have a few older machines that doesn't have the protection at all

      @@justme5384 - there could be internal electronics that perform that function. Such an electronic circuit would have a MOSFET that is normally switched on when voltage is above the low voltage discharge level, and then that MOSFET is switched off when the battery voltage drops too low. Only needs the two external terminals for that.

      @@stevebabiak6997 probably it is then in the battery, the newer ones has a 4 led indicator and when the battery is flat the last one starts to blink. I'll have to try it with a blinking one and see if the Ryobi still runs with it

      @@justme5384 - that is the test. Be careful to not deplete too low, because some batteries have some chips in them that remember they were drained too low and then won’t take a charge.
      The Ryobi batteries can usually be run until the battery stops putting out voltage (although I have one where I did that and it now won’t take a charge - have to open it one day, but it’s only 1.5Ah and I have several 4Ah batteries so don’t really need it now).

      Hi, use existing developed bits where possible.
      Just add a fuse (always a good idea) and a low voltage cut off circuit and away you go!
      Good one M.
