Really good analysis. I run a full range of 20 volt DEWALT tools but use their 60 volt portable saw. I own several 20 volt batteries and 2 Flexvolt. It’s a great system to allow 60 volt power where it is needed but gives high capacity 20 volt where needed like my high volume leaf blower. Having a little more understanding of what’s inside and it works is very helpful. I did not know that the cells were larger than 18650’s

Hey I’m glad I watched your video ! I learned so much . The first one was the way it switches voltage . I am also like you hopping to see more of this in the future. Then the way it’s wired learning that along with the size of the battery’s. That helped me out so much I have an after market battery that’s bad I’m going to rebuild. I would have ordered the wrong battery’s. Then you tell what mAh they use that helped out a lot . I like how you describe everything so plain it’s so easy to understand . I have subscribed to your channel as soon as the video was over. I look forward to learning more in the future you are a great sensei ! I have always wanted to have more wisdom on electronics . I was happy to learn and build a 13.8 volt DC battery charger from an old microwave transformer . An by using 8 AWG wire it has a high amp charge around 30 amp . With a 6 setting porch light timer switch I can set it for 10 min to a hour . I used the vent area off an old hot water tank to make the box I put it all in. Thanks for your great video and all of your wisdom on this battery pack !

I just took a 6ah pack apart that is built the same way. It takes a lot of skill and time to get the cells free since the black plastic on the sides goes over and under the metal tabs. It took me 3 hours to get it all apart. It's also difficult to not short anything out. I had one cell that was zero volts and the four other cells in series were over charged to 4.42v.
@frankjackson2439

I find it’s just easier to cut the plastic out around the cell your replacing. If your doing a full rebuild it would make sense to take the time to desolder everything. But if your repairing an old pack with old cells it just makes sense to make a quick repair on a pack that will soon fail.

Great vid very helpful! You might find this interesting.. I just disassembled my 6ah DCB606. It stopped working for 60v tools but does still seem to work with 20v. Also the charger will show that it is charged, but I only get 1 bar. Dewalt is sending a new one but told me to recycle or keep the bad one.. Sooo, the fun begins!..lol ; ) I haven't tested for bad cells yet which is what I believe the original problem may be. But, when I opened it I immediately noticed (Per your diagram) the BMS -3 right side connection is burnt completely out, and -5 shows heat damage, but is still intact. Debating how to proceed.? I'll test the cells tomorrow and post what I find. Thanks for making the vid!

Great Video! I believe the 21700 cells are used by Dewalt for the following reasons; 1) better heat disipation (for bigger tools), 2)21700 can go all the way up to 5000mah per cell, 3)the physically bigger cell can deliver the same current as the 18650 without heating up as much per watt delivered. 4) by using the 21700 now with the 21700 in rather early production they can take advantage of the improvements with the new 21700 of higher capacity without changing anything except the cells. They will probably use the same BMS and definitely the same packaging so very little work to get even beyond 12ah batteries!

@fun_ghoul

For high current draw applications, you may well do better with the 6 Ah and 9 Ah packs. I can't rattle off the specs right now, but improvements of energy density often come at the expense of power density. Of course, the flipside is that the nickel strips max out even the lowest-current pack does @ 3P (Russell "Syonyk" Graves estimates 30 amps continuous, max). The DCB230 (and any subsequent 5S1P 21**0 pack) looks like a nice option for no-solder ebike power packs, when coupled with the now widely available 3D-printed battery interface adapters...if you can get them cheap. The benefit of that style setup is the ability to warranty battery packs with DeWalt/SBD if/when they fail from [definitely not abuse], as well as easy replacement of a small block of cells if one craps out. It's also a good setup as battery tech improves, as the "FlexVolt" shit indicates at least to me that SBD is committed to this battery interface for several more years. This means you can upgrade by just sliding some new packs on, at which point your old ones could be used for less "mission critical" applications and/or ones with lower charge/discharge current requirements.

Excellent analysis of the battery. Couple of questions though: 1. Are you inferring that that the -5 terminal is temporarily connected to the negative output pin or are you basing this on observation of the wires? Reason I ask is because it doesn't seem necessary since it would be connected in parallel in 20V configuration anyway. 2. What purpose does the jumper serve? I would guess it has something to do with onboard monitoring of tool function but not certain. Subbed and looking forward to getting a closer look at the terminal connections behind the switch!
@vuaeco
6 жыл бұрын
1. That's correct. At 23:30, the (-5) terminal is moved to a different position. So yes, it is just a temporary connection until the switch is pushed in. 2. I think you're correct about the jumper (for the black and red wires). And I also think it serves both as a monitoring tool and current carrying wires. There's a reason why these 2 wires are so thick.

The reason use 2170 than 18650 is the same reason telsa using model3 vs model S which is more energy density. When 2170 has the same cap as 18650 it increase the life cycle and can be upgrade not just from 2Ah cell to 3Ah but also 4or even 5Ah in the future
