How to make Balanced Battery Charger at home

[@fredmessina5352]

*This battery reconditioning program exceeded my presumptions. It worked on any drill battery, several AA and AAA batteries, **batery.repair** and any camera battery. The steps are simple and the act itself is exciting to do. No matter what type of battery you`ve got, it is sure to function again!*

[@normskilight]

This is not a balance charger. This is 4 separate chargers. Why not instead of buying 4 TP4056's buy a single 4A voltage regulator, and the money you save buy a 4x battery holder? No poor defenseless paper clips have to be brutally mutilated anymore!

[@amogh1773]

TP4056 can't be replaced with a voltage regulator. And yeah using paper clips for wires is quite preposterous

[@normskilight]

Well I had the half decent ones in mind, some come with voltage and current pots. They'll do CC-CV charging no probs.

[@malipetek]

but in module you dont adjust the current.

[@alphadeicide7491]

but in fairness those paperclips where talking shit behind his back so...

[@station240]

I agree, It's not a balance charger, as the batteries aren't even connected in series. I mean why bother with the switches if the TP4056 shuts down when the cell is charged anyway. Really bored with these I built X project by soldering wires between ebay bought modules. Someone build an actual charger from scratch, and prove they actually understand electronics.

[@malipetek]

This is not balanced this is just a stack of chargers. Change the title.

[@Jaultaub]

yes. it will not even word if the cells are connected.

[@6sensory]

I'm having trouble seeing the 'balance' part... I see a common B+ & Common ground, but no link to change anything

[@orange11squares]

there is nothing to change, each tp4056 module will charge the connected cell to exactly 4.2V.

[@6sensory]

Yes, of course, but it says "balanced". I have the 4056 in an array of ten and there's no balancing or they'd constantly be tied to whatever cell might drag them to its lower voltage. They're set at one amp but you can move a part for lower amperages. Not balancing.

[@borisjevic6338]

4 bank independant charger ;-) Balancer would mean that you can USE their voltage to for V out, but lets not get toooooo technical about it. A real balancing circuit would have more parts, i.e resistors or transistors to switch the load between the batteries etc.

[@jwuethrich8385]

if you charge each cell independently you technically get a balanced charge. have you ever looked into how the most common balance circuit works? its wasteful as fuck and not great fort the cells. this needs some control circuitry to enable series use and cell isolation for charging but its the start of a much better balance charger than 99% of those sold

[@bayviewboom4468]

@Johnathan Wuethrich, if one cell has an inherent lower capacity than the other cells, then it will not charge to the same level as the other cells, right? Balance charging means all cells charge to the exact same V, right? Meaning, all cells should be limited by the cell with the lowest capacity, correct? cheers

[@YourLocalBomber]

Can you tell me about the power supply? I understand each board is 1a output so the power supply should be min 5a correct? What voltage is ok is it 5.5v max or would it 4x that so 22v for 4 boards. What supply did you use I can see a mini usb cable and that is all

[@goodtech1]

No a 5v power supply is enough as all the modules are connected in parallel. However, the maximum supply current of my power supply was 2A, so i could only get 500 mA per battery. I used a 5v 2A smartphone charger as power supply.

[@YourLocalBomber]

+GOODTECH - Creativity and Science so if the power supply only puts out 2a then it will just divide the output to each battery and you don't need any resistors etc? I'm doing 5 boards and 5 cells so my supply should be 5v 5a maximum correct? I'm using mp1405 though but not using out connections

[@goodtech1]

yes, for 5 boards in parallel a 5v 5A power supply is required.

[@YourLocalBomber]

Thank you for replying and good video !

[@eirikmurito]

that was awesome! what will happen if i use one chargin module for all the batteries?

[@goodtech1]

All 4 batteries connected in parallel charged with single charging module will require a very long time for the batteries to be charged and also the batteries will be damaged.

[@eirikmurito]

***** oh. anyway did you find a good box to mount the chip in?

[@Ostrica391]

GOODTECH - Creativity and Science batteries wont be damaged in that configuration.

[@illuminator4633]

Damaged? How exactly?

[@borisjevic6338]

You can use just one charging module, this is common practise for the vast majority of battery banks that use more than a single battery cell, they are all wired in parallel. The full current will also be distributed between the cells. There are a few drawbacks to this method is: 1. You MUST HAVE cells manufactured from the same batch and when 1st charged, must be at the same value, i.e. 3200mAh, 3180mAh 3210Mah all at 4P15V (4.15V) or 4P2V, then you can use them in the same "box". Second drawback, if one cell fails, the others besides charging your equipment will try to keep that faulty cell charged too. Now, using a cell balancning method, similar to the one shown above, this particular one has a major drawback/ flaw.TP4056 does not have documented what will happen if you have it set to charge at 1000mAh (1Amp), you connect 4 of these modules in series and you only have a 1 or 2 Amp USB supply, it can actually SHORTEN either 1. The battery life, do to it not being consistant. 2. Damage the IC (although they are fairly robust), 3. Overload your power output by puting a huge demand, 4. USB CAN MELT if you do NOT HAVE A GOOD ONE AND YOU HAVE A 4 AMP SUPPLY. IF you want to charge like this "balanced", the look for charging IC's with a "PowerPath" Controller, since you program the maximum current, and if the current is not enough, they automatically lower it so as the input voltage will not drop. This long reply is for the benefit of others too. :-) Have a nice day.

[@weazeldark3983]

This is genius ish Loving the paper clips

[@garywatson8602]

I don't care if it is Balanced or not I think it is a Really Neat and cool project to do ....I build this Last night with a few Changes , I omitted the Paper clips And used Battery Holders ,And I left the Switches Out since I could not see How to connect them , And I added a USB Cord To power it all , And Added a Voltage Meter .. Works pretty good as a charger ... Thanks for the Video and Idea ...

[@goodtech1]

You're Welcome :)

[@ynfe]

Please Please What material do you use to install welding

[@yougolook]

Is there a product like TP4056 the will manage my 26650 LiFePO4 s ?

[@goodtech1]

Yes, there are many products now available. Check one here - ebay.to/2vGPJzi You can also use a bq24650 IC and make you own circuit. Refer to the datasheet here- www.ti.com/lit/an/slua565/slua565.pdf

[@Lowpropo]

if i get this same circuit but i add wires to the batteries to create a high voltage series output would it mess around with the tp4056s while the batteries are connected? even if i cut off the output?

[@goodtech1]

If you connect the batteries in series, the TP4056 will not be able to charge the batteries. So, there is no point in connecting the batteries in series in the same circuit. You can remove the batteries from the charger and make a separate holder to connect the batteries in series and when batteries get depleted, you can again use this charger to charge the batteries.

[@daxxmo]

que tipo de cargador utilizaste para la carga de las baterias?

[@davidefem320]

Sir its a nice one,is the battery recheable

[@goodtech1]

Yes, these are rechargeable Li-ion cells found in Laptop batteries or mobile powerbanks.

[@jirun2359]

and in aku tools think

[@andonrangelov8844]

good. Can you use your device also in in reverse? i mean can you use it as battery bank from the same terminal that you use to charge it ?

[@goodtech1]

Thanks :) Yes, it can be used as a powerbank but you will need a switching circuit such that when the battery power falls below threshold, it indicates a discharged powerbank and then enable the charging of batteries through input terminal (micro USB port).

[@jirun2359]

I have this tp4056, but If I put two batteries in one tp, module charging, but never are charged-never blue :( do u think, its problem with two and more batteries to one tp?

[@goodtech1]

Ji run No, a TP4056 gives 1A at 5v, you can connect as many batteries as you want with TP4056 but only in parallel and the problem will be that the batteries will charge very slowly but they will surely get charged in time.

[@jirun2359]

so will be blue after day-2 or more... :D

[@goodtech1]

Depends on your power source. If you use a 1A adapter, then 2 Li-Ion cells(2000mAh) connected in parallel will get fully charged in almost 4 n half hrs.

[@arrowstheorem1881]

Though the use of paper clips may be viewed by some as inappropriate, i think in some cases, this is a perfect solution! Eg. when prototyping in the lab.

[@uttamx2016]

Nice Videos !! i saw after buying from Amazon.

[@poontikwah]

Is it possible to use two of such TP4056 modules to individually charge two 18650 batteries that linked in series?

[@goodtech1]

Nope. If the batteries are connected in series then you need atleast 7.5 v to charge two 18650 batteries connected in series.

[@poontikwah]

you have misunderstood my question, each chip is connected to one 18650 only, but at the same time, the two 18650 is connected in series, you may think that i am using two chips for balance charging

[@xtopheve2500]

No, it can't be done because they would have a common ground, which would short the whole thing out. It is however possible if you use one separate power supply for each TP4056 chip.

[@CaraAmar]

super creative design! gj

[@viswanathanramakrishnan7613]

Superb work. Really a different thinking in making a charger with gem clips and PCB board.

[@darshangowda8665]

bro this is awesome.It really works.Thank you goodtech

[@allexrock2795]

This could work for lipo batteries as well? I would like to charge 4s lipos 1300mAh

[@goodtech1]

Theoretically it will work with any 3.7v batteries but LiPo batteries are very different from other rechargeable batteries so extreme caution is needed to keep the batteries at optimum performance over a long time. A normal TP4056 charger charges battery with about 950 -1050mA of current but a LiPo battery should be charged quite slowly with around 500mA. You can easily modify the charging module to make it work well with LiPo batteries as well. Have a look at the tutorial here, it might help you - www.electroschematics.com/10551/tp4056-lipo-battery-charger-rc-toys/

[@blackholenebula1714]

whats the brown plate that u put the metel on? is it a custom circuit board? i also lked this ✌✌.also can u do this with d batterys or 9v batterys?

[@goodtech1]

This is a general purpose PCB board (available on ebay and amazon). TP4056 modules are made to charge 3.7v Li-Ion cells, they will not be able to charge 9v batteries.

[@niniliumify]

nice layout. I need to order some switches!

[@borisjevic6338]

just remember, they are "locked" swithes or "On/OFF" don't get the momentary contact ones of which look the same.

[@flux6826]

nice idea i liked it

[@namanlath3740]

whick batteries u have used

[@goodtech1]

These are 3.7v 2000mAH li-ion cells found in mobile powerbanks or laptop batteries.

[@Porama6400]

It's called 18650

[@kukusclan2012]

fantastic please, measures pcb board?

[@goodtech1]

PCB board size will vary with the components size and their placement. However, i used a board of about 5x8 inches.

[@kukusclan2012]

OK thank you

[@lurkingcorsa10]

powerful creativity..

[@thomaslorenfriedman]

Подскажите, если я правильно понял, то этой платой без всяких сторонних устройств на прямую можно заряжать акумулятор? Или нужны дополнительные запчасти или платы? мне просто постоянно нужно заряжать 18650, а зарядки дорогие. Заранее спасибо за ответ.

[@goodtech1]

Никаких дополнительных деталей не требуется. Только модуль Tp4056 и мобильное зарядное устройство. No additional parts are required. Only module Tp4056 and mobile charger.

[@thomaslorenfriedman]

спасибо!

[@joeestes6318]

now here is a project i think i can try!

[@DragonMaster5050]

Could this type of charger be used to charge AA or AAA batteries? Perhaps if a different charging module was used?

[@goodtech1]

This charging module is suitable to charge 3.7 v li-ion batteries. However, with a different suitable module other batteries can also be charged in this manner.

[@zeba3728]

Great advice

[@zeba3728]

thanks for your info

[@carsnboys]

hi. after disconnecting my laptop charger my batter dies in 5-7 minutes. so i remowed my laptops batteries when i checked them it varies 3,82 - 3,83 3,84 - 4,07 so i charged with tp4056 so i have some question 1- how long should i charge them 2 how can i understand they are charged fully 3 after a 10 15 minutes charging some of my batteries decreased 4,07 to 4,02 even they are free (not charged or used) is that normal? 4 what can i do apart from those techniques ( by the way i am not experienced of electricity i just watch videos :) thanks from now on

[@ericklein5097]

you probably already figured this out but for anyone reading with similar questions: 0. Your battery is dying fast because they cells no longer have the same capacity, they have degraded and now likely have a couple hundred mAh each. Voltage doesn't really indicate much except after charging you are seeing a voltage in the low 4's instead of 4.18, 4.19, 4.20, 4.21. Those are all voltages I would expect a new/slightly used cell to sit after charging. It's ok if your cell charges just a little past 4.20, I would not use a charger or TP4056 module that charged a cell past 4.22 though. As the cells degrade you'll see the max voltage decreases. A well worn cell will get below 4.15 and that's usually a good sign the capacity is quite low. This happens because the internal resistance has gotten much higher within the cell, this is a natural part of cell degradation. 1. How long to charge a cell? There is no answer to this question. It's a matter of math. A 2000mAh cell, or 2Ah, will take over 2 hours to charge at the rate of 2A however I wouldn't charge this fast. Charging is best done at 0.5C or lower (0.5*Cell capacity in Ah). So a 2Ah cell charged at 1A should take about 3 hours.Why not two hours? Lithium Charging has two stages, constant current and constant voltage. CC takes it up from its discharged voltage to 4.20V. CV starts when the cell hits max voltage and the current slowly winds down. CV will stop when current is 0.05C or 0.05*Capacity so 50 milliamps. Most chargers just cut off at 100mA which is fine. So the initial CC phase will take up to 2 hours for a fully discharged cell and the CV phase may take another hour for the current to wind down. Some use lead acid charging terms and call CC "bulk" and CV "absorption". There is not float charge with lithium. It is only 2 phases, CC and CV. DO NOT float charge your lithium batteries they don't need it and it will overcharge them. 2. The TP4056 LED indicator will change from red to blue. Nearly all chargers have some kind of indicator. If one is not present, check the voltage. When it reaches 4.20V leave it on for another 15-30 minutes and remove it. If you have the ability to measure current then check to make sure the current is decreasing after it hits 4.20V. If it is not then you do not have a proper charger and I would not use it. If you must use it, turn it off the second the cell hits 4.20V. Voltage will drop a little bit in the following 30 minutes but its very little capacity you are missing out on. If you were to leave that cell on the charger it would almost certainly overcharge the point of exploding. 3. Like I said earlier, your cells are settling at their resting voltage which is lower than normal because of IR. 4. There is nothing you can do to recondition Lithium Ion cells. Anyone that says otherwise is trying to start a fire in your home by instructing you to do something dangerous. Buy new cells, not from Aliexpress or Amazon. 18650 Battery Store, Lithium Ion Wholesale or Bulk Battery in the US/Canada. In Europe NKon and Fogstar are popular. If you buy from a place that cater to the vaping crowd expect to get hit with 300-400% markups.

i have a better idea, take out the switches, just parallel every module and put the batteries when needed

[@weazeldark3983]

Might be lazzy n want leave them in

[@bimaotong]

Can use the modul to charge Lithium Ion Battery 3.7V?

[@goodtech1]

Yes, this module is designed to charge 3.7v Li-ion batteries.

[@flux6826]

nice idea i loked it

[@jamesandonian7829]

Can you make an adapter so you can charge lipos using the lipo charging end? Can't remember the actually name...

[@darshangowda8665]

please tell me how can you make this using one charger module

[@goodtech1]

Connect all the batteries in parallel then a single module can be used to charge all the 4 batteries but the batteries will be damaged over the period of time due to over charging when connected with a single module.

[@OrbitalSP2]

GOODTECH - Creativity and Science -- they won't be damaged in parallel. Just won't. If a cell has a higher voltage it will charge the others with lower voltages and they will all balance out a 4.20V max. They will never go above 4.20v if the IC never lets it go there. What can happen is if you place a very discharged cell alongside a charged one. Them the charged one will unload high current into the other and that might be bad for the cables or the cell itself.

[@goodtech1]

Li-Ion cells in parallel work very well as long as they are in exactly the same condition but it is very rare. Even if one cell is degraded, it will affect other cells and will never let them to be fully charged as they will have to compensate for the lower voltage of the degraded cell, Also, the degraded cell might overheat while charging and other cells will never reach 100% capacity, thus degrading and damaging other batteries. It is always suitable to charge LI-ion batteries individually.

[@correia707]

So, charging paralleled batteries is not possible? For instance, if i place a 3p battery pack, how can i safely charge it? (taking into consideration i cannot remove batteries from a inclosure)

you can't use TP4056 in series unless they all have their own isolated 5V supply

[@mrgrid6395]

Добрый вечер! Скажите пожалуйста я сделал себе зарядное устройство на двух паралельно соеденённых модулях TP4056 (03962A) для зарядки двух банок 18650 (2200mah), заряжаю это чудо мобильным зарядником 5v 1A. Вопрос можно ли в этой сборке использовать зарядник с планшета 5v 3A?

[@goodtech1]

Да, вы можете, но каждый tp4056 будет использовать только 1A. Таким образом, батареи будут заряжаться быстрее. Yes, you can, but each tp4056 will only use 1A. Thus, the batteries will charge faster.

[@TheVovaDen]

Напрашивается вопрос можно ли в параллель, в другой микро USB, к такой сборке подцепить ещё один блок питания увеличив таким образом ток?

[@alexcuvajevs1477]

Там 4 модуля они могут работать каждый по отдельности. естественно их паралелить не нужно хоть на каждый свою зарядку. а так всё в паралель будет заряжаться по времени больше. Блоки питания паралелить нельзя просто запаралелить по 2 модуля и пользовать 2 блока. Зарядка будет идти быстрее.

[@chrisleech1565]

The only reason you would need a balanced charger is if you were managing a series arrangement ie. - 2S, 3S, 4S and so on, ie. laptop battery packs; ie. batteries such as those used by the RC community and those chargers manage balanced charging, amongst a host of other tasks necessary for managing the health of the high cap LiPo. It is a great project though and would use the single 18650 holders for a nice touch. For goodness sake man they are practically free!!!

yes.

[@borisjevic6338]

Yep, and you MUST USE A VERY GOOD USB CABLE. This is a MUST, unless you like the smell of melted rubber/ plastic and a possible fire hazard. USB cables that CAN handle that amount of current without voltage drop do exist, you just need to search for them. Just google: 22 awg micro usb or 20 awg micro usb. If you charge it with thiner cables, you will have a bigger voltage drop, and then the charger MAY throttle back on the current, or it will try to pull the full current and there goes your cable ;-)

[@priyabratasaha5385]

You should not say it balanced. tp4056 are self capable of balancing 1 cell. For multiple cells, balanced means you can charge all the cells in series with a same power source.

It isn't balance charger! Its only a 18650 charger

[@Schjoenz]

I was expecting a balanced charger but I think it is not. You basically have used 1 module for each battery... I have created a powerbank using 6 batteries in parallel connection with just 1 TP4056 module. It's working just fine and I've been using it for months now without any problem. I can charge the batteries for 7-8 hrs because each cell has 4000mAh capacity... But I can use the powerbank for 2 days.. I just didn't know exactly how many times I charged my phone because I just randomly charge even the battery is at 50-60%... I played games a lot so I used to charge more often...

[@punpck]

hmm, I guess the cells are not connected together to form a 4s battery pack? Imho that won't work because the batteries are not galvanically isolated ...

[@goodtech1]

No, the cells are not connected to eachother in any way. They are 4 cells in parallel orientation with independent charging modules.

[@elecdroid3666]

this is not a balanced charger . balanced chargers are charging serial connected batteries. am i wrong?

схема балансира строится так что каждый акум соединяется + к - и так по цепочке и от каждого соединение между + с - выходит один провод т.е. если мы заряжаем 6 акумов то у нас 7 проводов. 2 силовых и 5 соединении. и они одновременно должный заряжатся а не так что один акум на 15% заряжен а второй на 30% тертый на 10% и т.д. он должен выровнять вольтаж всех акумов и потом идет процесс зарядки. т.к. как по мне тут 2 проблемы конструкция точнее схема подключение не соответствует балансиру и я не знаю вроде бы чип tp4056 не умет заряжать и балансировать.

походу блок питания должен быть ампера на 4 :)

[@Sorca777]

Че блок питания на 4 ампера?)

[@goodtech1]

То ще разпредели равномерно тока, ако използвате 2А, ​​а след това 500mA за всички батерии. (Translated Text) It will distribute the current evenly if you use 2A, then 500mA for all batteries.

the 1 cell does not have switch

[@dominiktulak120]

Because one cell will be active everytime, u are just turning on another cells. ;)

[@RFC3514]

So, where exactly does this video show how to make a balanced charger? Do you even understand what a balanced charger is?

[@goodtech1]

A balanced charger is a charger that maintains all the batteries at the optimal charge without overcharging any single cell. When multiple cells are connected and charged using a balanced charger, the charger charges each cell only upto its optimum voltage. If a cell with short capacity reaches the optimum voltage quickly then its charging is stopped but the other cells still continue to charge. Similarly, in this all the four cells are connected in parallel. suppose, if a 2A charger is connected, each cell is charged with 500mA(ideally) but when one cell(with short capacity) gets charged then its charging is turned OFF and other cells continue to charge with 666mA(ideally). You can also connect multiple cells in parallel abd charge them with a single TP4056 module but in that case all the batteries will be charged to same voltage and the cell with short capacity will be forced to charge and thus damaged over time.

[@RFC3514]

No, it isn't. What you just described is _a group of independent (i.e., essentially separate) chargers._ A balanced charger ensures the charge of all batteries is approximately equal (based on the cell with the lowest capacity), to reduce the risk that you'll over-discharge one of the cells when using them together. Hence "balanced". A charger that charges different cells to different levels based on their individual capacity isn't *_balancing_* anything, it's just charging each cell independently.

[@goodtech1]

Yes, I think you are right. Thanks for clearing my concept. But if this is true, it means that if one cell loses its capacity then the whole battery will lose its capacity too because other cells will also not be charged to their full potential. Is there also a way to to overcome this disadvantage??

[@RFC3514]

The alternative is to allow that cell to discharge too much, potentially catching fire (this is what will happen if the batteries are too unbalanced and there's no BMS on the device where you use them). The point of balancing their charge is to make them safe(er) to use without constant monitoring (i.e., the output device only needs to monitor the overall voltage). If the device does have a BMS that monitors each cell, you can charge them all to full, but the BMS will still cut it off when one cell gets too low (or will actively discharge all the other ones to the same level, which adds up to the same).

[@MikeysLab]

This is not even close to a balanced system, none of the chargers know the voltage level of the other cells, and there is no way for the system to get rid of excess voltage. This merely charges 5 batteries at once. There are so many really bad tutorials like this one on LiPo batteries. Given how dangerous the batteries can be, someone is eventually going to get really hurt.

make me one

[@봄바람이-e4j]

밸런스는 아닌거 같은데요... 그냥 충전인듯

[@muffinman3630]

A parallel charger is NOT a balanced charger! WTF??

[@ธรรมธวัชหอสุวรรณ]

Wrong title. It not balance ,it just single cell charger! So bad.

[@pooorman-diy1104]

not a balanced charger ..

[@marcelihryniow211]

This is not a balance charger, it does no such thing as balancing.

[@HoRNET_FPV]

wtf is this lmao

[@siux94]

This is stupid and wrong way. You cant use these batteries in parallel anymore..

[@ВиталийРомадин-д6ы]

Сомневаюсь што на скрепочках будет ахуевший контакт

[@beefsupreme5291]

use your words just like you were a big boy

wastage of breadboard and solder.
