Once you are familiar with the diagram, you can use it to troubleshoot electrical issues and ensure that everything is working properly. 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! These are normally used for cell balancing during charging, but with the switch depressed, they can be connected together to produce 60v at the B+/- terminals. Nominal voltage is 10.8 volts.

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. Your best bet is to use a fuse that blows with less current then any wire it feeds. 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. 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. Solved This gave me access to measure each cell in the battery as well as some control signal inputs. This is a fast, heavy-duty Pulse Engine derived from my Commercial grade desulfator.

This Lithium Ion Battery is compatible with all DEWALT . Embedded hyperlinks in a thesis or research paper. DEWALT. 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. *Maximum initial battery voltage (measured without a workload) is 12 volts.

Because I'm going to be charging 9 batteries (3 in series x 3 in parallel,) I believe I need a circuit, then, that can generate an output of 6A (2A * 3 in parallel, ignoring the 4A stage) through a range of voltages from around 54V to 59.4V to charge all at once. Replied Who makes the LS IMR-18650BB cells? What do we know about them? Id guess theyre made in China. IMR signifies lithium manganese oxide cells (LiMn2O4). This is a good power chemistry - it trades off energy storage (mAh) for output amps. In general, you can pick where you want to sit between them, but something like a super high energy capacity cell (3400mAh) will sag badly and generally not like you pulling 30A off it. A power cell may only store 1500mAh, but will do 25-30A all day long and not care. Yes, thats an awful lot out of a little battery. Yes, modern power cells can do it. Thicker wire is less safe because MUCH moe current will flow before it melts through and opens the circuit. To make the experience fit your profile, pick a username and tell us what interests you.

With a little bit of practice and patience, you can learn to read a wiring diagram quickly and easily. Reddit and its partners use cookies and similar technologies to provide you with a better experience. The main integrated circuit on this board is a S8254AA chip. Its a standard little battery management IC that handles shutting down the pack if the voltage is too high or too low, and it supports multiple levels of overcurrent protection (so you can start a motor, but not sustain that power for too long, while still shutting down the pack instantly if someone were to try and short it out). I didnt test the overcurrent protection. - An interesting note, here, is that I measured no current across any pins except the TH pin. Is "I didn't think it was serious" usually a good defence against "duty to rescue"? To subscribe to this RSS feed, copy and paste this URL into your RSS reader. 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).
