Get the most out of your 12V MAX tools on the jobsite with this 12V MAX Battery Starter Kit. Hello all, Great information here. This particular battery outputs 20v by default; using the 20v mode is as simple as making connections to the B+ and B- terminals. Asking for help, clarification, or responding to other answers. What differentiates living as mere roommates from living in a marriage-like relationship? It is important to take your time to read and understand the diagram and pay close attention to the color coding of the wires. Be aware though that using power tool battery packs is probably the most expensive way of building a 60V battery. I'm voting to close this question as off-topic because as presented this question is a plea for consulting services which this site most assuredly does not provide. Most are 20v, but the Dewalt Flexvolt can also output 60v. A sag of 2.84V on 4A implies a total system resistance of 710m, which is super high for something like this. But, testing with my handy gizmo gave me per-cell internal resistance measurements in the 150-180m range, which is incrediblyhigh. You should see 30-50m for a cell like this. That high measurement means the cells are old and worn out - probably both. Without an original spec sheet, I dont know what they were supposed to be, but not this high. This pack has lived out its useful life and should be recycled (or re-celled, since its got enough smarts in it to be more than just a case for cells). 04-25-2017, 03:41 PM.

If I were some random YouTuber, Id probably just short the pins and see what happened. But thats not really science. There are no numbers to that process. Also, I really, reallytry to avoid shorting battery packs. Fortunately, I have a good load bank. Hook things up, and, yup. Just a hair over 12V on the pins. You can also use "20V Max" chargers to charge any 5S li-ion (or lipo, I guess) pack with compatible charge rate, as long as the charger "sees" 10kOhm resistance from "TH" to "B+" (emulates a 10kOhm-at-25C temp sensor), and ~1kOhm from "ID" to "B-" (DW's pack identification scheme, which presumably controls charge rate). dewalt 12v battery for sale | eBay 18V XRP Battery Pack | DEWALT Private Hackaday API, By using our website and services, you expressly agree to the placement of our performance, functionality, and advertising cookies. Active Before I dive in, lets inspect the top. This pack has the same general connection layout as the bigger lithium packs - two double height pins on the end, and six sockets in the middle. Annoyingly, these arent labeled like they are on the newer packs. I did a bit of probing around with the pack assembled and couldnt make any sense of what I saw, though. Unless DeWalt has done something very, very weird with this pack, its quite stone dead. Its lost in the reflection here, but someone did write Bad in faded marker on the latch. So, probably dead. Also of note, on the right side, you can see a 2010 build date under the muck. Probably week 34, if its a normal build date encoding, so late August.

DeWalt tool 12 V battery pack - what is the code for the ID pin? I suggest getting a single pack that has the voltage and capacity you require, rather than trying to repurpose a product that was not intended to be used this way. Looking at the pins head on, the far left pair is B+, and the far right pair is B-. This is the same as the newer packs, which means if you have something sized for the 20V Max packs, and find yourself needing less voltage, and less capacity, the interface will work more or less the same. Battery Warranty 90-Day Money back guarantee and up to 3-year free service agreement. Note that the gerbers included with this project plot the bottom copper layer. Your Dewalt battery does not have a smart chip inside. To understand what it takes to charge a DeWalt battery, I built a test rig, depleted a battery, and sampled the current and voltage during the charging with 1 battery and 1 stock charger. I suspect this is related to the 3rd pin. My great experience with my bike batteries spurred me to buy both of these, knowing how much battery tech has advanced! I've also made a different version of this and here's Love this Idea and roybi has a 40 volt battery out now. I'd be ok with using a microcontroller to monitor the charging cycle and control different states in the process (ex: from 6A to 0A when charging is complete). Like most of the DeWalt packs, the cells just pull out (with a tiny bit of prying if theyve been corroded in place), leaving the bottom of the case. Given how much dirtier one of the cell housings is, its possible that a cell vented, but the pack was filthy on the outside, and it still could be a lot of water damage. I just dont know what happened here, exactly. The metal actually went "everywhere", Some peole might think you can make the project more safe by using thicker wire.

Its been over a year since Ive posted anytool battery teardowns, and it shouldnt surprise anyone terribly much that Im the sort of person who collects tool batteries wherever I roam. This week, Ive got a pair of cute little 12V lithium batteries to pull apart - one DeWalt, and one Ryobi. Hi nicholas, welcom to EE stack exchange, my first suggestion would be to check the chemistry of the batteries you are using, that is what will determine the charge procedure/IC, then try researching about the battery packs themselves, they most likely will have protection circuitry and probably balancing (in this case you may want a circuit that supports balancing). DEWALT 12V/20V Max USB Power Source DCB090 - The Home Depot You can see the interconnect leading straight to the end terminal on this side. The other side is the same. Like the 20V Max packs, the end terminals are double height (which makes sense, as theyre the main current carrying terminals), and theyre always live. If you were to stick a conductive object in the end pins, youd find pack voltage, and its up to you to monitor the pack voltage and keep it from deeply discharging. Id recommend running this pack no lower than 9V. Youll be a hair above 12V fully charged (around 12.3-12.6V depending on where the charger quits), have useful power down to 9V, and below that, youre just abusing the battery for no actual energy extraction. But, definitely hobbyist friendly! The PCB can be screwed into the adapter body or glued, making sure that the PCB sits flush or just under the inside surface of the adapter body. Flipping the board over, weve got a little thermistor in the top left corner, a UP72 UCHIYA thermal fuse (configured for 70C), and a big diode going from the negative plane to the positive plane. My guess is that this handles reverse polarity connection - if you were to try and hook up a charger backwards, this diode would short out your charger, at least after the battery bank drained through it. Its the type of thing that Im sure exists for a reason, but I cant figure out where it would reasonably be used. If you tried to force current through the pack backwards, youd drain the pack down to the low voltage cutoff (fine), and then when the transistor closed, youd end up dumping current through the diode. Its a weird feature, but here it is. It shouldnt do anything in normal operation, but if you happen to know whythey have this, Id love to hear about it! 50. You've done some impressive work researching your battery packs, but it was unnecessary. What is this brick with a round back and a stud on the side used for? Source: I piss around with battery packs in my spare time. When AI meets IP: Can artists sue AI imitators? I'd like to stick with these DeWalt packs over sourcing others, though, as I like their robust casing/materials/and onboard balancing/protection circuit. for pricing and availability. Chart (noisy because of cheap equipment): Note: I limited the Y-axis of the voltage to 18V-20V, each of the C1 through C4 pins shows the same line as TH but scaled to represent the lesser number of cells measured across (I felt relevant cutting that portion of the graph off as there was no current across the lines leading to those pins).

If you reproduce the charging profile of the DeWalt charger then theoretically it should work. The bottom of the pack has the usual warnings about reading the instruction manual, which probably would say things like, Do not disassemble this pack. Not having an instruction manual, obviously, I dont know any better than to just whip out my Torx T-10 drivers and go right in. I mean, theyre not even security bits! However, out of curiosity, I did probe the end ports - and, hey! Voltage! This works out to 4.02V/cell, which is nicely charged. I can do some testing on this pack! Price and other details may vary based on product size and color. Click here. DeWalt DCB120 Battery Pack(about $25 on eBay for a genuine one)is a Type 1 battery pack (the 20V Max packs are Type 2), rated for 12V (Max), and 15.6Wh. Ive messed with enough DeWalt packs to know that their capacity ratings are determined by someone in marketing with a calculator and not any of the engineers. If you divide 15.6 by 12, you get a neat and tidy 1.3 - so Id guess the cells in here are 1300mAh cells, and three of them. Now, if I were to call this pack something, Id call it something like 11.1V, 14.4Wh, but thats me. I will nevermanage to get myself hired as a tool battery marketing type. The ID pins appear to be both roughly 110 to B-. And the TH pin seems to be a 10k NTC thermistor connected to B- as well. Im not sure about the remaining pin. Id say its not connected, but I do get some connections to some pins through it. On the other hand, I also get about 20M between pins that shouldnt be connected at all with the pack disassembled like this, so Im not sure how much of that is intended and how much is the corrosion leaking.
