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. 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. Ratchet Kit, XTREME 12V MAX* Brushless 1/4 in. With a little bit of practice and patience, you can learn to read a wiring diagram quickly and easily. The chip handles the charging of the battery completely on its own, with a single 5V power supply (most if not all those modules have a USB socket on them). (have not tried 20V tools yet, considering the extra C3 pin and a lack of 20v tools to dick with) I'd like to use DeWalt 20V 5Ah batteries to supply this power, 3 in series x 3 in parallel (9 total). If I was using these packs I would make them removable and charge each one separately on the official charger (that's what I do with our drone which takes 6 removable batteries, and it takes half a day to charge 3 sets). No problem, if you open up a typical cordless drill 18V / 20V Battery pack, there will be 5 cylindrical cells hooked up in series (S).

Or wait, is it really 190A? Maybe its less. Maybe its a lotless. Maybe the package can only handle 75A. At least this datasheet is a bit more direct about the problem. DigiKey has a great article titled, When Datasheets Attack, talking about this very issue. If you actually sit down and try to work out what would be required for a part to meet their current rating in the face of actual thermal behaviors of parts, you rapidly find yourself considering things like liquid nitrogen. Plus, at high currents, a printed circuit board is not build of superconductors, so it will help heat things up as well. Theres no way this part could handle 190A at all, and even 75A is suspect in reality. But, hey, it looks like itll survive 750A until the legs or internal wire bonds fuse Be careful out there! And if it seems to good to be true, it almost certainly is. I thought about being done here, since the pack still worked, but then I looked at the voltage sag.

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.

Their charging process is well described. Use MathJax to format equations. 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.

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).

Home Understanding The Wiring Diagram Of A Dewalt 20V Battery Pinout Diagram, June 21, 2022 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.

Almost exactly 8 years ago to this post, which long predates this blogs existence. and I built something that uses a battery about this size and thought I had circuit protection but didn't and accidentally the wires shorted. If you reproduce the charging profile of the DeWalt charger then theoretically it should work. B+, B- and a third pin which is either a thermistor (TH) or an identifier (ID). 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). A wiring diagram is a simplified representation of the physical connections and physical layout of an electrical system or circuit. Im going to explain what I'm doing as I go and a how to do the same y Today I will show you how I build a battery box to power my electric bike using cordless tool battery.

Here's a rudimentary diagram of my setup: What I learned, in broad strokes, is that the Dewalt charger applies a constant current of 4A until the output reaches around 19V, then it switches to a constant current of 2A until the output must be around 19.8V. 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. Why? I would assume the downside of a catastrophic failure with this type of battery is much less than a LiPo.

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. I could use help designing the circuit to control the charging. 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.
