With the pack fully charged to 20.5V (4.1V/cell), I set the tester up for a 2.0A draw and ran the pack down to 15V. I dont know what the high temperature cutoff is, but if you are using this pack for your own projects, be aware that the cells will be a good bit hotter than the thermistor indicates. Power tools draw higher currents and have sporadic drain rates minimizing the opportunity for the battery to develop a memory. Sane enough, though one LED means you really should be charging it now. Just the opposite. Remove the battery, once you feel a loss of power from the tool. The exposed balance wires (coming from the center of each H interconnect) go into the board and are routed to the C1-C4 terminals in the center (since these dont handle nearly as much current, they dont have to be double height). Time to tool up? Use it as intended, dont run it below 1 LED if you can help it, and it should keep you going for a long time! Finally, the circuit board handles the ID and TH pins as described above. Im absolutely comfortable calling this a 6Ah pack - it meets specifications just fine. The previous pack I pulled apart had a pair of 15A rated cells, for a total pack rating of 30A. The back of the board is entirely passive components.

It has the same terminals and latching mechanism as all the 20V Max packs - which does make sense, given that they all need to fit in the same tools. Weve all been there, our battery indicated that it was fully charged. Its not going anywhere. Corrosion at the battery terminals is not a sign of a bad battery but may lead to a bad battery if not corrected. When the alternator is defective or running at the wrong pace, it may produce too much electrical current which will end up in the battery thus overcharging it. You can unsubscribe at any time.

And inside is just a scaled up version of the 18650 based pack I tore down previously! They are dead as granite. Sitting in the trunk of a black car in Phoenix in the summer will also kill them early. How? Hi, I'm Eric the blogger behind ReadyToDiy.com. These are hardcore power cells - a single cell at 30A is putting out over 100W! Looking at the discharge curves for the cell (from the previously linked PDF), Panasonic considers the cell fully drained at 2.5V - which is absurdly low for a lithium cell (and works out to 12.5V across this pack). The following are trademarks for one or more DEWALT power tools, accessories, anchors and concrete adhesives: The yellow and black color scheme; the D-shaped air intake grill; the array of pyramids on the handgrip; the kit box configuration; and the array of lozenge-shaped humps on the surface of the tool.

If this cycle continues, the battery may suffer thermal runaway which will destroy the battery. Back in 2016, I tore apart a 3.0Ah pack I had laying around - that particular one had a bad cell group (dead short in a cell - that must have been exciting when it failed), so it was quite unusable and I couldnt really get much data on it. The same goes for B-. MPN. The electrical interface is a bit more interesting - and, really, quite a bit of fun! This new pack is supposed to be twice the capacity at 6.0Ah - or, as the front cover helpfully explains, 50% More Capacity vs DCB204 4.0Ah Battery. Math!

So, bring your security bits trying to keep me out. Hint: I brought it. There is no way that the BMS can cut off current if the pack voltage is low. Because why not? The low capacity (1500mAh - below half of what a high energy cell can do) is the price you pay for a cell with that kind of power output. The increased resistance will make the battery heat up and this will cause water in the electrolyte to evaporate leaving the battery without acid. Theres basically no excuse to not have one in 2016.

Dry the connection and the battery terminal before reconnecting them. In fact, it is better for the battery to leave it in the charger to be sure it goes through Equalization and Maintenance Modes. Not fully charging them, and not running them totally empty (as is the case with the DeWalt charger and, ideally, users) is a lot easier on the cells and should keep them alive a lot longer. Is it any good? Where some people get confused is when they see a flashing red light. you will notice after folding and unfolding the string of batters that the 12 batteries are wired in series pos-to-neg, neg-to-pos and so on use the gummy insulator that you pried away from the top and bottom of the batteries to draw a template then use a coin to complete the circles representing the batteries draw a diagram looking at the batteries from the bottom then draw a Unfortunately, this one is really only monitoring pack temperature - not cell temperature. These, obviously, dont work with regular Torx head bits. The board has the ID resistor and thermistor as well, but it is by no means a battery management system - it doesnt appear to do any balancing, and is quite simple.
