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. I am working on my daughter and sons power wheels.

I'm working on a project that will require a 60V DC (mobile) power source. a member for this project? 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).

We take extensive measures to ensure all our products are made to the very highest standards and meet all relevant industry regulations. After a bit of probing around on this corroded mess of an interface, I figured out a few more things. C1, the voltage after the first cell, is definitely the top pin, second from the right. C2, the voltage after the second cell, is the lower pin there. And, of course, if you want the voltage of all three cells, just use the B+ connection on the far left. 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. 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. 12V MAX* COMPATIBILITY 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. Time to tool up? 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). Wow, they both really kick butt, my previous e drill was an old nicad 12 volt. It means that the charger does the balancing, the logic is inside the charger. It is also important if you want to make sure that everything is working properly. This is a fast, heavy-duty Pulse Engine derived from my Commercial grade desulfator.

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.
