Increase charging current TP4056 

👍🏾👍🏾👍🏾👍🏾

de hecho a mi me prendio fuego la bateria Xd

who cares? Hype is must.

çıkışa zener diyot ekleyebilirisiniz. ayarlı olan tl431 olan bu işi görecektir diye düşünüyorum.

Maybe there is resitor on board

I'm pretty sure the pin on the board is already driving an onboard FET. This is adding an extra Fet in parallel to that.

@@robmc3338 There is no external power mosfet.

@@robmc3338 😂so is it practical to do this reply

I agree with You. This kind of batteries are really dangerous when You Charge them with higher currents than the nominal.

@@jjcreacionessoluciones Definitely a very dangerous video. Not everyone is as knowledgeable as we are.

I guess it makes whatever amps it gets, as the FET works in a switch mode :)

.

among other things, it is not certain that the current is distributed uniformly in all 4 cells, some could absorb more, some less increasing the risk of overheating.

Thanks for watching

окончание заряда контролирует микруха, по напряжению на банках.

@@РоманХашматов да, но CC/CV тут явно не работает. Вернее, работает только ограничение по верхнему напряжению. Но там должны быть всякие trickle charge режимы и т.д. Будут ли они корректно работать или нет неизвестно.

@@wirtdonners4212 известно. не будут. Тут показан вообще "апгрейд" для идиотов желающих спалить свой дом. Здесь просто вставили ключ (транзистор) который тупо напрямую подключает АКБ к источнику питания. И разомкнётся только при достижении на батарее 4.2 В. Токоограничения кроме сопротивления проводов нет (если его нету у БП).... Да лучше тогда просто плату защиты поставить и так же напрямую к источнику подключаться.

@@ОлегСелян-х9ж Согласен, так себе идея.

As well as the temperature of the external field effect transistor. After all, the power on it will stand out considerable./ Равно как и температуру внешнего полевого транзистора. Ведь мощность на нём выделяться будет немалая.

hi, what is 1C mean?

@@ClassyJohn It means the Capacity of the battery. Example a 1000mah battery which is 1A battery can not be safely charged at 1A and it could cause damage to the battery or even make it explode. The typical safe recommendation is 0.5C which is half the capacity of the battery, so 500mah charge rate in this example.

@@Angryhelder What if a battery is charged with less than 0.5C, like 0.2, will it damage the battery?

@@naingtheawperc3817 preferably you want 0.5c or less so that is fine.

схема плохая! транзистор не может регулировать ток и это не минуемая гибель акб или вовсе взрыв...

Это схема хороша если ты пожар хочешь устроить. В этой схеме отсутствует ограничение тока. Вернее оно есть но только лишь из-за сопротивления проводов и мощности БП. Просто поставь плату защиты на АКБ и подключи напрямую к БП и будет тоже самое, даже лучше, потому как у платы защиты есть хотя бы защита по току.

He bypass the IC with Z44 MOSFET

At 1:34 you can see on the pinout of the TP4056 that pin 2 connects through R-PROG to ground. This resistor's value tells the chip which output current to use - so it has "programmable" output, up to 1000mA. The pre-installed resistor will be chosen to provide this maximum rating. With this hack, this circuit (output current regulation) as well as the circuit for voltage regulation are bypassed. So, you are feeding whatever voltage and current capacity your power supply provides directly into the battery. To answer your question, then, it is the internal resistance of the battery that dictates the current draw, up to the maximum rating of your power supply - 30A in your case. The battery's resistance would certainly limit the current to something less than that, but it would very likely be too much current for safety. Therefore, the only function then that TP4056 is now providing is the charge termination, which is supposed to cut off the charging circuit when the current draw reaches C/10 ...typically this is around 100mA. It is unlikely that the TP4056 will provide this function at these higher voltages and current. So, if you're thinking of doing this hack you might as well just connect your battery directly to your 5V source!

Yes, this is just a test.

@@PhdHung I understand. Just telling other people. Also, this mosfet has a little bit high Rdson for 10A. Check out the IRF5305

I think banks should be charged to the minimum of 10% of their storage capacity, for example if I have a 100Amp bank I must charge it to 10 Ah, so as not to increase the internal resistance every time I loaded it, the idea is great only that that mini battery bank is too small to load it that way. If you want to charge so fast, better use Ultra LTO Capacitors

@@rickhuntraslam2925 what you mean is you want to never discharge below 10%... there is already a security threshold. We do no discharge Li-Ion or Li-Po under 3V per cell, yet each cell could get down to about 2.5V before any real damage happens! Also a 100A bank doesn't mean anything, it's 100Ah! A are used to measure a current flow! Ah are used to measure a capacity, it's how much A you need to draw to drain the battery in an hour! That is a very common mistake I have even seen on official products like more or less famous bluetooth speakers!

@@Zebra_Paw ok

при такой схеме контроль тока зарядки вообще отсутствует.

Заблуждение. Зарядный ток литийных элементов может быть в половину от емкости батареи. Не путайте со свинцовыми.

why? is it because batteries have a capped current limit they can support?

@@ClassyJohn Because rechargeable batteries work by a reversible chemical reaction. Too much current will cause internal heating that can damage the cell's internal structure. In addition, for some chemical reactions, too much current can produce a different non-reversible chemical reaction to occur, thus lowering the cell's capacity.

Are you sure it's great?

@@tuxede I don't think it's working, however i give it a try. When it work, the energy problem is solved :-)

@@richardnoordhoff4288 it isn't creating more energy, it just allows more current flow. that is possible, and for that this will work, however the schematic also showed a protection diode which is missing here, as well as you need to be sure it won't remove the protection functions of the cirquit. more curent(certainly) does it still protect the batteries(Perhaps, it does to a certain extend, but should still test it anyway).

True, but if you keep in mind that there will be 9,1A charging current you have to choose a ≥10A power supply.

за блок питания не переживай переживать надо за акб ,транзистор не может регулировать ток и это не минуемая гибель акб или вовсе взрыв...

Unfortunately, it's real. The TP4056 is still only supplying 1A (and has internal current limiting for over-temperature anyway). But the circuit is using the "charge" indicator output to turn on an external MOSFET between the supply and the battery and that is supplying the extra 8A. The IRF9540 has a resistance of around 0.2 ohms when turned on fully, so the current is being limited crudely by whatever the power supply is capable of. Not a safe circuit.

En estos casos, no necesitas un balanceador extra.

I think the original charge board will turn off the mosfet when the battery reaches 4.2V via the pin with the 10 ohm resistor he added.

well i just tried 4 and seen smoking coming from it so its not 4 haha

The maximum charging current is limited by the power supply itself. The gate resistor does not affect the charging current.

~40*C

Somewhat 2V at 10A, "40C" is only if you live on a pole lol. Well, unless (and I guess that is exactly what happens) he overloaded the power supply so it is what defines the current, not the useless charger.

5V 2A is almost too much. By wiring the MosFET via the LED charge indicator, it gets an enormous current gain. Combined with the low resistance value and the polished, highly efficient copper antenna, it can convert the missing power from the magic around it. Sorry for the joke, but output power can never be greater than input power. If you want 5V 10A at the output you have to provide at least 5V 10A at the input.

just add 2 modules on top of another in parallel, you will get 2A

@@JawadAhmadsahibzada I connected two TP4056E modules in parallel: for some reason, the output current did not change. On one of the boards, two diodes are lit at the same time.

@@sddfefr5686 I used 4 tp4056 in parallel to charge my power bank quickly. I tested around 3.8A going to power bank. But make sure you’re using 5v 2A charger minimum for 2 in parallel

@@louisgabriels6333 a little bit over 1C is not an issue

How do you balance batteries connected in parallel? It doesn't need a resistor, the current regulation depends on the connected power supply.

@@wernerpeter9706 just skipped on some part lol but you can do balance the batteries using a resitor to lower the output from source or like you said just change the supply to 4v 2a

@@tossancuyota7848 That's not balancing, that's charge control. In a parallel circuit, there are no voltage differences between the individual cells that need to be balanced. If you set 4.2V and 2A on the laboratory power supply, why do you need a modified TA4056 module? In this case, 2 cables are enough ;-) So this modification is not only dangerous but also pointless.
