The H interconnects are placed a bit more precisely than the interconnects on the older pack I tore apart. Lots of solder, lots of thermal wicking, and lead free solder leads to needing a serious amount of heat. 1. C1, C2, C3, and C4 are direct access to the voltage of each cell group - so, as shipped, 3.5V per cell. So, cool! What Happens If You Overfill The Battery? My 3.0Ah packs read exactly the same. Skipping ahead slightly, I measured the thickness of the interconnect strip used. This means I cant pull the PCB off to observe the underside without starting to dismantle the pack with a soldering iron - which I dont care to do. The cells are rated a bit more if you fully charge them to 4.2V/cell, but at 4.1V/cell, it looks like this is pretty much exactly a 6Ah pack. You wont see a true 6Ah in operation, but thats true of pretty much every battery out there - theyre rated in ideal, low draw conditions. Always charge them after use. Should any special precautions be taken when transporting or traveling with batteries? McGruff the Crime Dog says, Dont sniff lithium batteries.. This means the battery corrosion is acid in nature. I'm a homeowner and I like to do things myself. Im reasonably certain that this is also one of those things the manual told me not to do - Ive jammed some conductive spade terminals directly into the pack and am discharging it through my FDY10-H battery tester (which I will review at some point - I love this little gizmo for bulk testing). Corrosion will cause the charge current reaching the battery to be reduced. Itll provide a general idea, but nothing nearly so useful as a set of thermistors on the cells to find if one is running hot and suggest the user back off. C3: 8.19V (4.09V) Does it hurt DEWALT batteries to leave them in the charger? The back of the board is entirely passive components. NiCd batteries lose the bulk of the capacity when outside of the charger in the first 3 days. And, again, if Id run it lower (which I dont like to do), Im sure I could have pulled a full 6Ah out. To call it a 20V pack requires a nominal voltage of 4V/cell, which is just weird (and not what they have). DeWalt offers a 3 year warranty on these packs, and Id expect them to easily last 3 years. All you do by draining the pack deeply is hurt cycle life. Probably less. If I can rebuild the pack radically cheaper than I can buy a new one, Im likely to rebuild it. 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! In mobile phones, some Li+ battery packs have 3 terminals.

Type 2, whatever that means. Im not surprised, but as one who deals with the proper dangerous goods/hazmat shipping for battery packs on a regular basis, I really dont like to see batteries shipped around in violation of shipping laws. And to obtain similar 30A rated batteries, Ill spend more on cells in small quantities as I will on a brand new pack. I keep going! 3. 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. No. After removing the conformal coating, I measured10.68k at 21.6C - so probably a standard 10k/25C thermistor. Easy to install ,locks on you battery very well. 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. One of which is very much included in this 100 piece set. And inside is just a scaled up version of the 18650 based pack I tore down previously! Again, a beefy, beefy pack. 100% positive Feedback; Save this seller. The only real complaints I have are that the BMS is really just a balancing board, and the thermistor is more or less useless.
