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. These are *relatively* safe compared to Lithium Polymer (LiPo). Wow, they both really kick butt, my previous e drill was an old nicad 12 volt. 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. I built something that uses a battery about this size and thought I had circuit protection but didn't and accidentally the wires shorted. Not a member? Click here.

I would assume the downside of a catastrophic failure with this type of battery is much less than a LiPo. Yuck, yuck, yuck. Corrosion everywhere. Nasty cells and interconnects. This particular battery outputs 20v by default; using the 20v mode is as simple as making connections to the B+ and B- terminals. and last updated 4 years ago. Look for labels and symbols that can help you understand the diagram. There is a guy on youtube who uses dewalt and other packs to power his hub motor bike. Sold by Electronics Club and ships from Amazon Fulfillment. Get into tight areas and cramped spaces with sub-compact tools designed to fit where you need. On the Dewalt there are 8 connector pins. A couple T10 Torx head screws laster, and Im in. And wow. Yuck. Ive seen some nasty packs, but this is up there. Gross. Its quite corroded, either from a vented cell or from being quite wet. Price and other details may vary based on product size and color. But for reliable operation you should connect directly to the cells and have a balancing circuit that does all of them at once, so if you do it properly the existing case and balancer are redundant. Finally, the pinout youve all been waiting for! The board actually has the terminal names printed on it, so while theyre not on the outside case, its easy to work them out. B+ and B- are the end connections, obviously. C1+ and C2+ are the per-cell taps, so youll see about 4V and 8V on them, respectively, against B-. T1 is the temperature sensor, a 10k NTC unit again. And, T2 appears to be a 7.5k fixed resistor - so the ID pin for the tool to identify the pack. Enjoy! If my project is successful I will be sure to contribute an updates back here.

You are about to report the project "DeWalt Flexvolt 60v Battery Adapter", please tell us the reason. . 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. *Maximum initial battery voltage (measured without a workload) is 4, 20, 60 and 120 volts. It is mandatory to procure user consent prior to running these cookies on your website. 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. 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. Two voltages. FWIW, a quick perusal of the internet suggests that this unit uses Lithium Ion batteries. Recent Posts Unread Posts Tags, Forum Icons: With the cells out of the way, I can get around to working out the pinout on the interface. Shop products from small business brands sold in Amazons store. 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. I thought about being done here, since the pack still worked, but then I looked at the voltage sag. Its not a useful pack, and I dont own any Ryobi tools anyway. Why not keep going? I thought I saw some cool stuff on the bottom of the circuit board.

Besides the positive and negative posts there are six smaller pins labeled. 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!
