7s is a better configuration for 24V if using 3.7V nominal cells. Also, from the looks of that wire that 12A BMS will not protect the wire from insulation failure from overheating due to exceeding it's ampacity.
Any concerns regarding soldering directly on batteries, no thermal probe on the battery pack, and how thin are the wires to the terminal? how much amperage through them before they start getting toasty?
Never try soldering to a relatively large chunk of metal like a battery even with good flux. Given a little rough handling they will fail. If you want a starter project make yourself a cheap spot welder .. plenty of examples on UA-cam ... then join the batteries with strip metal.
7S is far better for a 24v lithium ion battery 7S at 100% charge will deliver 29.3v which is perfect for powering 24v devices like power inverters and portable fridges.etc 6S will still work but you will get vastly lower runtime and in the case of DC motors, you will also get lower performance to keep the rectangular shape, have 7S in a straight line or use an even P number (7S 2P for example)

Jeffery .W Its really hard to solder a 18650 battery. There is a coating that solder doesn't stick too. So you need to sand down the ends. Also use a wide tip soldering iron. But its really not a good idea to solder 18650 batteries. To much heat. If you care about your batteries the best way is to spot weld them.
Can you combine multiple battery packs. For example if you wanted to stack the batteries in a tube instead of connecting them all next to each other in rows
if you had more amperage that drill would work better. if you double the size of the battery, you can still keep your current setup. all you would have to do is double up each of the positive and negatives.
Do you think you could do a 18650. Rechargeable portable solar bank power and just for the hell of it a small DIY wind turbine. Lol i like to see a bug out solar set up. If thats not to hard?
A reinvented car battery. Most auto batteries were designed back in 8 cylinder days. Every car now has 6 or 4 cylinders. Perhaps, not as much need to start a 4 cylinder, so no need to carry a 60 lb battery. Just a thought.
The way you would build a 36 volt pack, as opposed to this 24 volt pack, would to just add more cells in series. The cells he's using are around 4 volts each, and by connecting them in series (ie. positive to negative to positive and so forth...) the voltage is added together. So, 6 cells at 4 volts each would net around 24 volts. By the same token, if you added an additional 3 cells that output 4 volts each, you would achieve your desired voltage of 36 volts. The protection circuit might need to be changed out in this case, but that is essentially all that would need to be done in order to up the voltage. Hope this helps!
PARALLEL 2 OR 3 OR 4 of these "2000 PERFECT" (these confounders ((18650's and such)) Babes! :O) In addition to the movments like no tv, fast vehicles over 35 or lack of psychic war pt A and Omega too! AGAIN THIS IS A NICE NICE VIDEO! well done!
Hi, great video. If I want to give it more capacity by connecting 4 of those 6 cell units, in parallel, is it just a matter of each unit having 4 of the same BMS as in the video or do I need a single, different BMS for the whole battery? Thanks.
Hello, I need help.Does all 18650 Battery needs to be same capacity (half are 2500mah and other half is 3000mah)? Doing it for my bluetooth speaker.Tnx
So what is balancing the cells? you may get away with it for a while if you only use a lite load, but when you use them cell to drill with or any other heavy loads will throw the cells out of balance. A 6S pack 25.2v charger is needed to properly charge, why? First the charger builds the voltage and holds it there, then the current is topped off, you need a power source that does constant voltage - constant current cv/cc 4v per cell is fine, but this is a bulk charge not balanced, right?
Hi great vid I have an old 24v masonry drill and the batteries are scrap. Would this power it and give good run time also would I be able to use the drills own charger. Cheers William
Can I connect a second pack of 6 batteries to the same driver on the same meats to get more endurance. That is, will this charger manage to charge two packs of 6 batteries at the same time?
The person of the video, is not answering the questions. The six batteries are connected in series in two groups, The terminals for each battery are to be connected as, 6v, 9v, 12v, 15v, 18v, and 21 volts , marking available on the bms board. The minus terminal is to be connected on the board lastly only after connecting all the positive leads to board
24 volts will only take the cells to 4 volts each in theory. a 25.2 volt charger would be required combined with a means of balancing and controlling the current.
Does this battery module have under and overcharge protection? So if the voltage rate say drops from 24 down to 17 does it have a cut off switch? Also does this battery module have overcharge protection? Like if you plugged in a 28 volt charger would it accept it knowingly that the batteries will exceed the safety voltage? And on the same coin what is the lowest and highest voltage Chargers you can connect to this to make sure it gets up to its maximum voltage? And one last question what if the six batteries that you're putting in even though they're all rated it's a 2000mah, are not at the same voltage when you connect it to the board? Does it have Smart charging circuitry so it knows that one at 3.7 volts you'll need longer to charge someone at 4 volts, without possibly causing an explosion or fire for overcharging? I would love to hear from you

So many risks, so little advice to protect the inexperienced!! 18650 Li-ion cells can catch fire and become fireworks! This is more likely to happen when soldering wires to cell!! Much safer to spot weld! The combustion events can happen days or weeks after soldering.... Do not try this at home, unless you know exactly what you are doing!

Sir , 3.7v x 6 = 22.2v so how it will give 24v ? & one more confusion can I use 4 cells in 6s BMS & hookup 2 BMS for getting 24v . ?
The discharge value is 3.7 volts but 4.2 volts at full charge. Then 4.2 volts x 6 cells = 25,2 volts.
Is that BMS is great for diy drill
