... 3 things which will prevent this from exploding : 1# use a better charging controller 2# dont use diffrent sized capacity/voltaged batteries 3# do not create such things
Actually the different size/capacity is not a problem at all because of the way he's using them. He has them wired in parallel as one gigantic cell. Any difference in capacity or charging doesn't matter because the cells will always equalize among themselves. Say you had one cell at 3.2 volts and the others at 4.2. The moment he soldered them together, the 3.2 would have started charging off the others, and the 4.2's would have lost voltage until they were all equal and the same voltage. The same when charging up. This is how most ultrabook batteries are set up, with different sized cells spread all over the interior volume of the device, but running in parallel.
I do agree that I wouldn't trust that charge controller. As for your #2 @Subparanon already told you the facts. #3 I made an ebike battery using 130 18650 cells. It is setup in a 13s10p format. Nothing pisses me off more than ignorant people telling me that I'll blow my self up.
@@Subparanon Parallel-connected batteries with different capacities are charged / discharged unevenly. The battery with the lowest capacity will be charged first, and the battery with the highest capacity will always be undercharged.
Good job, the only thing I would have done different would be to add an external charge port that could be hooked to a rc car battery charger....the charger in the input is at best 1000 mah.... so 50 hours to recharge it

@@justADeni why is the voltage 8v? because this is a fast charging battery, the output voltage of fast charging is dc3.6-6 volt 3 ampere, 6-9v 2a, and 9-12v 1.5a
50,000mAh is crazy for a powerbank and it would take ages to charge up! I'd also be very dubious of how those Macbook battery cells were arranged together. Personally, I'd have used 18650s in parallel, and to a more modest capacity (one that won't take hours to charge up), thus saving the Macbook battery cells for something else. Plus, the whole pack will be limited by the weakest cell - if one cell fails, the whole pack goes. You also need to run a capacity test on those cells to see how much capacity they have left!
Those mac batteries are 3.8v nominal and 4.35v full charged, not the standard 3.7v / 4.2v batteries. It needs a special charger. Also cells were not tested. What to say about different capacities mixed in the pack. It's a complete fail setup & implementation.
I don’t get why people are so against this All the cells are in parallel so the capacity of the cells adds up and doesn’t matter the size of the cell. There are no cells in series so people complaining about no balancing are fear mongering. The PCB has built in protection for over current, short circuit, overcharge, under charge, over temperature and will disconnect the battery if there’s any issues. As far as the 8v goes that’s how it charges quickly. Say you have a cable rated at 2 amps, under standard usb 5v you will have 10 watts available but if you raise the voltage to 8v still with 2 amps you now have 16 watts without burning your cable. Now the pcb will take that 8v and use a buck converter to lower the voltage to li ion charging Levels of 2.8-4.35v
I have a few power banks I built, most are 4.5ah to 6ah, I have one that's 15ah plus, and I'm going to build one about 20ah with 8 USB out, and 9watt led light, being off grid, its good to have power and light, I have a 118ah 4s LiFePo4 bank, that is solar charged with 300watta solar, its for led lighting, radio, and has USB output, I'm thinking about adding a 12v- 120vac inverter, of about 800-1kw, so incase my main 24v systen goes down, I can keep my fridge going and have TV! I need to figure how long 118ah will last! Great video!!!
Protective card must be on each battery. Then the difference in capacity between the batteries will not matter. But the total capacity will need to be measured by the weakest battery.
When they are in parrallel they all balance each other the higher capacity cells will drain into the smaller ones so they stay at the same voltage the same as parrallel charging
They will drain each other out of control. High drain continuously will stressed the battery. All lithium or polymer battery have short life cycle. Charging the battery in this condition will make battery more hot and soon it will die.
1. The batteries are in parallel so no need of any balancing 2. The board included is a 1s balanced charger which will charge the batteries efficiently, 3. Different batteries capacities doesn't matter so far the cells are in parallel, it's just like 10 people pushing on a car, all their power combined will move the car regardless of the stronger or weaker person. 4. This is common sense, I don't think it's common anymore lols
I think the more likely problem is heat from constant, uncontrollable discharge on the larger batteries to keep the smaller ones charged. This might lead to fires or even an explosion.
Where did you get all the tools, the bins and drawers full of materials at your disposal? This is what I desire in my own shop but this takes time to achieve and years of collecting.
@If Perkov Why do people think this? the batteries will happily take a charge till they are all full but this will put a lot of strain on the lower capacity batteries, if you charge past the capacity of the lower capacity cells then you have created a constantly discharging larger cell and a constantly overcharging smaller cell, this creates what is commonly known as death!
It's totally safe other than the fact of those kinda blunt ridges in the case but he kinda held it in place with double sided tape I guess? Also kinda wished he check the capacity of the cells and if there is any self discharging cells since one cell can actually drains the whole pack. Other than that I kinda dig it, I make some electronic projects too and it amazes me how many amazing components people throw out such as transformers and such.

Kids, the batteries are in parallel, no balancer needed. You can also mix small and big batteries they won't explode. If they are at 4.20v then they are at 4.20, they won't get higher. Learn before sharing wrong thoughts :)
but watch again what he doing, he was tested all batteries and shows different voltage, he rather soldered all batteries in parralel than fully charge each battery before
@@azharschecter7076 I propbably skipped ahead too much to see that. But i approve, they should at least be at the same level or near the voltage of the others
When a small cell (let's say 1Ah) is connected in parallel with a large cell (let's say 3Ah) and a load is applied to them, the small cell will lose it's charge quicker, therefore lowering it's voltage. The bigger cell will compensate this by supplying current at it's max output to the smaller cell to charge it up (why max current? Simple, no limiting factors other than the internal resistance of the batteries.). This will destroy the batteries over time and create heat.
You need to learn about lipos, when a higher capacity bat y connected to a small capacity bat, the big is going to charge the smaller with a lots of amps

@step sister if u know what i mean you really need to pay attention to physics,amp (A) is a measurement of current ,while amphour (AH) is measurement of capacity.just like km is distance and kmph is speed
@step sister if u know what i mean As you are saying above that amps is the same as amp hours then I´m sure you don´t mind saying wrong units to other stuff either (maybe you do not even know what the difference is, other than a letter). What you are saying is that it is ok to say "My cars fuel consumption is 8 liters" or "While jogging, my maximum speed is 10 kilometers" or "My electricity bill was last month 200 kW". All those three examples are totally nonsence and the only outcome is that you make yourself sound like the worlds biggest idiot when using them or some other similar "short forms for units".

@@DrFailov there is a couple actualy, for the start, dont connect Li-ion batteries in parralel circuit, if batteries has their capacity in mah in different levels, this will cause cells to be unballanced and they will die quick, also, total capacity will not be the summ of all capacities used. Also, do not use ready dc-dc boosters like that, I would recomend to buy the one that is more powerfull, lets say capable of at least 20w of active power, so wheb you charge your phone at 10w peak, it would not get as hot as if you use 10w or 2amps 5v booster, because in second case it would be working at its max, therefore causing loss of efficency of capacity available... just adding my two cents!
@@CuXaPuK as you mentioned about different capacities, it's not a problem in parallel connection, besause batteries self-balancing. It's a problem in serial connection, so then balancer board is needed. As for DC-DC board, it's not able to output much power, so, it's no problem with overheating.

but watch again what he doing, he was tested all batteries and shows different voltage, he rather soldered all batteries in parralel than fully charge each battery before
@@azharschecter7076 I propbably skipped ahead too much to see that. But i approve, they should at least be at the same level or near the voltage of the others
When a small cell (let's say 1Ah) is connected in parallel with a large cell (let's say 3Ah) and a load is applied to them, the small cell will lose it's charge quicker, therefore lowering it's voltage. The bigger cell will compensate this by supplying current at it's max output to the smaller cell to charge it up (why max current? Simple, no limiting factors other than the internal resistance of the batteries.). This will destroy the batteries over time and create heat.
@@azharschecter7076 it is not optimal but this is ok here 3.7 .9 v
You need to learn about lipos, when a higher capacity bat y connected to a small capacity bat, the big is going to charge the smaller with a lots of amps
This poverbank can and car charge. Excellent, I also make interesting videos.
I watched your videos, it is very interesting. 👍👍👍👍👍
dont know spelling of power
Isko power ki spelling Nahi pata aur youtuber banega 😂😂😁😁😀😀🤣🤣
I see.
fabulous
It's a drift stone, isn't it?

Why not use other batteries
I have a bad feeling about it i think from the first use it will explode
Mshare AL-khuraiji nothing about a samsung in the video. it should be good.
hvpeconnections hmmm fair enough
.you r great bro.. amazing creative idea..bro
Nice box ! 😲😲
How much input 5 volt...? That was long very long time 😂😂
10 days to charge 😅😂😂😂
What's up with your pinky nail?
не то чтобы мне это понадобилось хоть когда бы то ни было в жизни, но смотреть довольно весело)
upd. провода и соединения батарей все же стоило сделать поболее, тогда бы потери на сопротивление проводов были бы куда меньше а мощность батареи выше
Good job i like a lot 👍❤👍
Great.. Congratulation..
Waitttt a second, Ur using different capacity batteries and without a BMS!!!???
ADSlammer they in parallel
@@joe070907080706 yes, but its not the best for it's health!
@@adslammer1359 No!
BMS is used when you connect serial
@@adslammer1359 you can't connect a bms to a pure parallel battery pack.
想知道行動電源都沒有獨立安裝保護板，在使用上沒有問題嗎？因為是用舊電池，在充電時不會爆嗎？
Olha quantos componentes a disposição, ele é oque? Milhonário kkk
Unico br nos comentários kkkk
wowoo 😮👌
Eso es una bomba de 50,000 kilotones, mas poderosa que la de Hiroshima y mas si nisiquiera son de la misma capacidad la baterías.
si we esa madre al conectarla a la corriente explota
Very good idea and a cool job.
where did you get that quick charge 3.0 PCB at please?
50A?! It'll take forever to charge!
and forever to discharge
It's not 50A ,it's 50Ah,the difference is like km and kmph
@step sister if u know what i mean you really need to pay attention to physics,amp (A) is a measurement of current ,while amphour (AH) is measurement of capacity.just like km is distance and kmph is speed
@step sister if u know what i mean I bet you are the person who also states that a human needs 2000 calories each day...
@step sister if u know what i mean As you are saying above that amps is the same as amp hours then I´m sure you don´t mind saying wrong units to other stuff either (maybe you do not even know what the difference is, other than a letter). What you are saying is that it is ok to say "My cars fuel consumption is 8 liters" or "While jogging, my maximum speed is 10 kilometers" or "My electricity bill was last month 200 kW". All those three examples are totally nonsence and the only outcome is that you make yourself sound like the worlds biggest idiot when using them or some other similar "short forms for units".
мне одно не понятно! откуда у этого х.. столько запчастей?
Most likely in his father workspace. Whole video is just a cringe of doing wrong things one after other. I am afraid to imagine what will happen when kids attempt this at home with even more mistakes, I hope no one dies, literally...
@@CuXaPuK what's wrong with this powerbank?
Он - из Китая, а у них всегда все есть))
@@DrFailov there is a couple actualy, for the start, dont connect Li-ion batteries in parralel circuit, if batteries has their capacity in mah in different levels, this will cause cells to be unballanced and they will die quick, also, total capacity will not be the summ of all capacities used. Also, do not use ready dc-dc boosters like that, I would recomend to buy the one that is more powerfull, lets say capable of at least 20w of active power, so wheb you charge your phone at 10w peak, it would not get as hot as if you use 10w or 2amps 5v booster, because in second case it would be working at its max, therefore causing loss of efficency of capacity available... just adding my two cents!
@@CuXaPuK as you mentioned about different capacities, it's not a problem in parallel connection, besause batteries self-balancing. It's a problem in serial connection, so then balancer board is needed. As for DC-DC board, it's not able to output much power, so, it's no problem with overheating.
