[@allamesancak9067]

probably that charging IC will burn to ashes until you fully charge those batteries, even there is a possibility that many batteries will explode because the voltage and ohm ampere values ​​in those batteries will not match each other, but sometimes if there is their own special bms inside the batteries, the battery will cut off the charge by itself without exploding, at most those 3 sister batteries. it will be good for you to use the mountain, let's be careful

[@paddyLaBelle]

Hello Electronic help care! I love your videos! You should be a role model for all western countries! Do not always dispose of everything, repair it! There is a small group of people here in Germany who work like you. It's called a "repair cafe". Old devices will be repaired again! I think that's great and so do many other people who come to us. I am also an active member of the "repair cafe" and have already copied some of your great tricks! Thank you for all the videos, keep up the good work and be our role model! Many greetings from Germany! Patrik

[@luisr9176]

That's a very dangerous work, cause you need a special bms circuit for that quantity of batteries (if you dont' have the good one, batteries can get overcharge and explode) also you need to recharge one by one of the batteries to have the same voltage and don't damage the others batteries when are all connected, and that wire solded between the 2 package of batteries must be selected according with the maximum current of the circuit.

[@nkhjk3457]

Luis R finally , i was searching through the comments because this video did not mention anything about wire gauges or battery configuration ... someone has notice how faulty this is finally.

[@pip5461]

Whatever he was doing, he clearly has no regard for safety... or bms ...

[@mohamed.foaz.]

[@Scott_C]

Yeah super important information. I too was looking for this in the comments. This should be the top comment. Remember kids lithium batteries (like the ones in this video) will explode if not maintained properly.

[@muungaemmanuel]

So this explains why my batteries didnt work when I connected mine I did this without watching any video so I thought that I was gonna get the longer lasting bank instead it was at it default state charging for 30 mins and working as it was with only one cell

[@franksmith7271]

Great video, I'd just like to say that its a good idea to charge and check the voltages in each battery and only pair similar voltages together, the closer to 4.2v the better. I just built a battery pack with 6 18650's and each battery was between 4.10 and 4.15v, the charging board in the video is the same one that I'll get in the mail today and I'm going to wire them together tonight.

[@meetv7700]

Yeah

Nice video and upgrade! Those fake powerbanks with sand cells are no good. Just a few points I'd mention: 1) This isn't a 20,000mAh power bank. With 5 cells, this would be 4,000mAh per cell. The maximum on the market is 3500mAh by Sanyo or 3400mAh by Panasonic, both very expensive, not usually found in laptops. Most 18650s from laptops are 2200mAh - 2800mAh when new. 2) It's not a good idea to just check for voltage and then solder together in a pack. You need to measure to at least 0.1V accuracy, preferably 0.01V or better. And you need to use a battery analyzer (e.g. a Turnigy Accucel or SkyRC iMax) to measure the capacity at a 1A discharge. Some laptop batteries are fine on voltage but hold very little capacity.

[@jkev1425]

Thank you, exactly what I though. Pretty dangerous to do it like that...

Charging is going to take a long time since its charged at 1A max(circuit limit). 2000mah x 3.7 x 5 = 37Wh (37Wh + losses) ÷ 5w = 8 hours of charging for fullcharge.

[@seitakiiiii]

The question is how long it will last?

Who cares? put it on charging when you go to bed. that's all. simple.

[@maciejpospiech4371]

And for whoever is watching this video there is warning for You. Please, under eny curcume stances don't solder this batteries directly, I learned it hard way, I'm actually watching this wideo in hospital after one of my 18650's blowed me nearly straight in my eyes... NEVER EVER SOLDER ENY BATTERY DIRECTLY!!! AT LEAST SOLDER TO STRAPS!!!

Boa tarde, essas placas pode aumentar o números de células sem problema? Deve ter um limite ou não? Tipo essa dai pode colocar 12 células? Obrigado amigo.

i cant tell if your resoldering the nickel back on to the cells but doing that could offset voltages and they could get hot explode or just stop working

[@0mkarMirkar]

Sand Nice... This gave me a smuggling Idea 😆😆😆😆

[@XxiMcRAzYLaZyxX]

Id also like to point out he never capacity tested the cells so how can he claim 20000mah. Those are most likely sanyo cells and none of them come at 4000mah a piece or by any manufacturer for that matter, He got scammed and this guy is scamming you people

[@gaelrodriguez2965]

in fact, if you count the cells, there are 10 diferent ones, the thing is that they not fit in the power bank module that he has, so he put in it less, event guessing that the cells are 2000 mah each one you can make a 20000 mah power bank if you put all of them together by doing the same process, the thing here is that he didnt specifically tell the people to build a 20k one but instead he shows how you can fit in one of those cheap chinese copies

[@hamzaahmad9489]

For your info, there are many cells available that have greater mah value in this cell size. For instance 8800 mah is available.

[@cosmos69]

@@hamzaahmad9489 lol, I know you are indian and you want to protect your scammer friend. The fact, even the top class manufacturers(samsung, LG, panasonic)could only produce these 18650 batteries with max capacity 3600mAH. The capacity of 8800mAH is only something your indian manufacturer can do with mouth and sand.

[@papaddzul5763]

Thanks for exposing the sand exporters. I had the similar experience. Mine wasn’t sand, though. A “protected” 18650 from China that wasn’t protected. A disc was attached at the Negative that had no electronics in it ! In your case “sand”. But look at the “sand batteries” don’t they look very genuine? I admire these basta##d$.

Generally those 18650 batteries are about 3500mah so if wired correctly there's definitely 20000mah of power there

No way it 20,000mah. There are no 4,000mah in a single cell of 18650 Li-ion. 4,000mahx5=20,000?? No way.. Single cell in laptop most 2,000mah or less. Used some more. Most likely 10,000mah or less.😁

[@cosmos69]

Without BMS circuit that is definitely an untimed bomb. 5 18650 batteries in parallel array, how did you calculate 20000mAH？

[@marianboteanu8163]

Yes i Was thinking howww 20000mah ? And when this bord charge all 5 battery maibe never

No it wont explode, BMS is necessary when using batteries in series connection. Charge discharge and short circuit protection is the only chip needed when using in parallel connections all powerbank PCBs contains them

4,000mAh 18650s do not exist. Max is Panasonic NCR18650B @ 3400mAh These looked like generic Sanyos @ 2.2Ah or 2.4Ah per cell (new) so will be less when used.
