I'm thinking some wired power supply that is able to interface with the standard battery connector on my tools, and provide the necessary power in lieu of a battery. The DEWALT FLEXVOLT battery is backwards compatible with our 20V MAX* tools so you 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). I'm working on a project that will require a 60V DC (mobile) power source. We'll assume you're ok with this, but you can opt-out if you wish. Why? $43.98.

Shop DEWALT 12-Volt 3 Amp-Hour; Lithium Power Tool Battery in the Power Tool Batteries & Chargers department at Lowe's.com. Before going any further, I had a question I needed the answer to: Does this pack need any sort of key to turn it on? Some packs will leak voltage to the terminals, but wont let you pull any power without some sort of secret code (pulling some pin to ground, or putting a resistor across two pins). I have connected 12 V to the B pins, and the tool LED lamp flashes momentarily when tool is turned on, but tool refuses to work. The 12V MAX* 3.0Ah Lithium Ion Battery provides additional runtime for our 12V MAX* tools, with 50% more capacity than the DCB122 2.0Ah battery. Will it do 4A? Yes, but also, seriously, ouch. Thats a nearly 3V drop on only 4A. My connections arent amazing, but theyre not thatbad. Where might I find a copy of the 1983 RPG "Other Suns"?

Fortunately only minor second degree burns then healed up well in about a week. Nominal voltage is 10.8 volts. I've also made a different version of this and here's Love this Idea and roybi has a 40 volt battery out now. At that second milestone, it maintains a voltage of ~19.6V and notifies the user that charging is complete by triggering the "TH" pin. Embedded hyperlinks in a thesis or research paper. Get the most out of your 12V MAX tools on the jobsite with this 12V MAX Battery Starter Kit. Most are 20v, but the Dewalt Flexvolt can also output 60v. Why the obscure but specific description of Jane Doe II in the original complaint for Westenbroek v. Kappa Kappa Gamma Fraternity? I intend to use regular Dewalt chargers to charge the system so charging won't be an issue and I intend to set up individual voltage cell meters for each pack to ensure an even usage and low voltage risks. 1996-2023, Amazon.com, Inc. or its affiliates. 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).

In the comments you say that you like their robust casing/materials/and onboard balancing/protection circuit. 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.

You are about to report the project "DeWalt Flexvolt 60v Battery Adapter", please tell us the reason. It means that the charger does the balancing, the logic is inside the charger. Here are some tips to help you get the most out of your wiring diagram: With a little bit of practice and patience, you can learn to read a wiring diagram for a Dewalt 20V battery pinout diagram quickly and easily. If you check the labeling of the contacts, C1 to C4 are actually the joints to the cells. By signing up you agree to receive emails from DEWALT with news, special offers, promotions and other information. 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). This a very good alternative to wireless microphones available in market. 120V MAX is based on using 2 DEWALT 60V MAX* lithium-ion batteries combined. Part of this project will be making a circuit that can charge all 9 of these at once, without removing them to put them on a separate charger. Sign up. Tool battery packs can make a handy portable power source for various projects. You can unsubscribe at any time. 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.

Visinilor, No. Most are 20v, but the Dewalt Flexvolt can also output 60v. Learn More. B+, B- and a third pin which is either a thermistor (TH) or an identifier (ID). Closed, Str. These packs are not designed for charging in series or parallel. However it may be difficult to get each pack to share the voltage and current equally. Not Replied Unlike the DeWalt 12V battery, the Ryobi labels the negative and positive terminals. Unlike the newer DeWalt batteries, the rest of them are a mystery, at least from the outside. I did a bit of probing from the outside, but its sometimes easier to figure it out from the inside. The main power connectors here are a single hunk of metal instead of the dual finger DeWalt style. Ive no idea which is better in theory, though in actual use I doubt it matters at all (especially for lower power packs like these). DEWALT. 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. 12V MAX* COMPATIBILITY I will connect three in series to achieve a nominal 54 volts.

The other piece of the puzzle is the connection between the C1 and C3 terminals. 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. created on 02/01/2018 A set of T8 Torx screws gets you inside the Ryobi. Take out the four corners, pull the top off, and well, thats a bit more substantial. And extremelyfamiliar looking. Last time I got into a Ryobi pack, I saw a BMS board that looked nearly identical to the board in a Rigid pack- and this board looks pretty close to both of those. On the right, you can see the manufacturer silkscreen - Wan Nien. Apparently they also make Craftsman batteries, if youre keeping track at home. There are labels on the board by the connections, which is super convenient, but Ill dig into the board a bit more later. *Maximum initial battery voltage (measured without a workload) is 4, 20, 60 and 120 volts. I will repeat that process three more times and then parallel all to achieve a 20 amp hour battery. References: Treat this project and anything you power with it the same as any mains wiring. I normally try to guess if a pack is hand spot welded or machine assembled, but this one is too gross to do much analysis on. Ill wager hand done, though, because its a 2010 pack, and Ive not seen any machine assembled ones of that age. Also, the soldering is clearly hand done, so its probably hand built. Talk about a boring job wait, Ibuild batteries! Extracting arguments from a list of function calls, What are the arguments for/against anonymous authorship of the Gospels. If you'd like to receive each new post by email, sign up here! Inside the battery, there is protection only, no "smart part". Pay close attention to the color coding of the wires. New Question. Turn the bank on, and I pull a nice clean 2A from the pack. But woah. That voltage drop. Id expect a sag to 11.5V or so on 2A, not down in the 10s. On the plus side, Ive answered my question: The pack will happily provide current if you shove wires in the terminals. Work overhead and tackle one-handed applications with lightweight tools built to minimize fatigue. Thanks for this project. But, for me? Ill stick with my DeWalt tools. The 20V Max line is clearly their flagship line going forward, with the 20V/60V FlexVolt packs being a thing, and Im not concerned about finding packs for a long while. They use good cells, and in some cases, its literally cheaper to buy packs than to buy bare cells. Volume is a good thing. Plus, since the packs are nothing but cells in a case, it wont be hard to find aftermarket ones long term.

Price and other details may vary based on product size and color. 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! DEWALT. I figured out to depress the switch and to short c2 c3 but I bricked one battery because I did not figure out that the switch had to be depressed first. Get it as soon as . I would suffuse a fuse on EVERY lead going to the battery, but at the very least one on the positive battery terminal mounted as physically close to the battery as possible. 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).

Log In. 6 Amp Battery Charger. If you're looking for a way to turn a dewalt battery to AC, I've seen dewalt - to - ryobi adapters and ryobi dc->ac adapter on top, allowing for a 120v plug Lie-Nielsen 2 yr. ago Dewalt makes something that looks like a battery but is really just the connector attached to a wire to allow you to plug tools in. Private DEWALT 20V/60V Battery has 12.0 Ah capacity for maximum runtime ; DEWALT battery is compatible with 20V MAX*, 60V MAX*, and 120V MAX* tools . I really like what DeWalt has done with their battery packs. Theyve moved all the smarts off the pack and into the tools, allowing them to have a pack that is literally cells in a case with a dumb interface board. Its a great way to build a battery for tool use, because theres nothing extra in there. The Ryobi pack is a good pack, but the BMS in there is wasteful. The tool can handle the low voltage cutoff, the charger can handle the high voltage cutoff, and the whole circuit board, in the common case, will be trashed when the pack is thrown out. Yes, it grants a tiny extra bit of safety if something goes wrong, but theres no reason you cant have a backup overvoltage detection system in a charger (and refuse to start charging if the voltage is too low). Most of it is just extra complexity, and extra things to go wrong. I dont see the value in that system, unless, of course, youre Wan Nien, convincing tool makers that they all need your battery management boards and battery packs. Not a bad spot to be, really. The best way to find the DEWALT cordless tool for your toughest jobs. Be aware though that using power tool battery packs is probably the most expensive way of building a 60V battery. The middle two barrier block terminals are not connected to anything. With no clue as to what these cells are in the pack, I keep going and separate them from the case and interface board. Still no clue. Given what looks (and feels) like an old pine needle in the top left, Im going to guess this pack got quite wet from being left outside a long while. And/or fully immersed at some point. But, seriously, dont leave your tool packs out in the rain. They wont run very long afterwards, and then someone like me will make snarky comments about you in a decade. The backside of the connector board is just a few passive components. I saw a tiny transistor on the front side, but wasnt able to get a good shot of it. At some point, I might buzz out the boards and see what exactly they have going on, but not today. Sold by Electronics Club and ships from Amazon Fulfillment. Store Finder; Truck & Tool Rental; For the Pro; . I understand that five of those pins are for the individual cells that are in parallel to make up the pack. Your Dewalt battery does not have a smart chip inside. 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.

Forum contains no unread posts Moved out of knowledge base which is more meant for answers not questions. 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! NLBA Laptop Battery Analyzer with Chip Reset & Repair Option, Can I test and charge with NLBA this Dewalt tools battery?
