not like that.... if if two batteries charge before the third battery will never charge... bcoz it will get get enough current to complete third battery charging...
the problem I see here is that the batteries are not connected together so there is not a battery pack as such, joining them together to make a pack of ~12v battery pack would short the diodes out and make them redundant...
I'm no engineer, but wouldn't the output of the modules be virtually the same as soldering or welding the cells together, but instead they're individually protected?
Use a proper 3S circuit board to manage the battery charging and discharging. There's many flaws in this design, as these boards are designed in mind to handle only one battery at a time. What you can do safely? Wire them in PARALEL not series with a source of 5V - 3Amps, and charge batteries in paralel without any connection to each other board.
@@jorgecarlosmogollonrojas5536 BMS should implement safety triggers for both charging and discharging. BMS should be used only for what it is designed for, like 1S BMS only with 1S battery, 3S with 3S battery and so on. You can put the same cells in parallel to increase the capacity while maintaining the 1S, for example, put 3 cells in parallel they are still 1S. IMPORTANT: Cells should be from the same lot (manufacturer, year, same usage, preferably new), and balanced when you put them together (have same voltage). It is, even like this, unsafe, as the BMS designed for 1S 1P (1 series, 1 parallel) would not have balance charging along all the cells put in parallel, but let's say if you respect what I've said (same lot, manufacturer, year, date, usage-preferably new), you are quite safe for 2 or 3 cells in parallel.
I either saw a RUclips video showing a person wiring these BMS boards in parallel or figured that out after seeing something similarly mentioned. I also saw in a video where someone applied thermal plaster and a small heatsink to limit heat buildup in larger 1s setups... still took the RUclipsr like 7 hours to charge the battery, but was able to constantly output 1amp safely. I never intended to follow this project, as I remember hearing of all the difficulty and risks of getting a few BMS boards to work together in series (I bought about 20 or so of these Lipos that are thin, like phone batteries, and come with a decent BMS installed already).
@@Suzuki_Hiakura It's not about heat, thermal safety or similar. 1S BMS can't handle balance charging, and can't current limit the output properly and so on. If the piece of hardware is not designed to work like this, and imply a possible fire hazard, then don't use it like this.
@@overPowerPenguin the first part of my comment was referring to your closing statement. My second part covered what I heard of using simple 1s BMS boards in series.
I'm no engineer, but if you connected all the modules' 5v charge inputs in parallel, you should be able to connect one usb cable to charge them all at the same time, no? That way you don't have to mess with inputting 12v across the three or charging one at a time.
Another vid introducing bad ideas to people, knowing even less, than the originator: Sure: connecting the single boards this way charges 3 cells at the same time, but you win pretty much nothing, apart from using a 12V source instead of one 5V source with more ampere: *) you still cannot use the charged cells as a 12V/11.1V 3s-power source. *) What about the charging current? IMHO it is limited to the current of the slowest cell. And what happens, if one cell isn't present at all?!?!? *) no real balancing function *) 12V will not load the cells to their limit of typical 4.2V, but rather 80% - IF cells are being drawn equally. *) the role of the diodes is not explained, nor the type/their voltage drop They look like some 1A+ type. (didn't look them up) *) soldering the cells instead of changeable slots -> if the cells are used quite differently, at a current >> the one the 4056 can provide --> smoke? The 4056 allows for different charging speeds (via changing some resistor on the board) - it'd be much more interesting, to have add a switchable current/capacity charger.
The correct when using the TP4056, is to connect in parallel, feeding with 5V and 3A or more, so you can load a pack 3s quietly without problems, because each cell will be charged individually. The B3 lipo chargers, use TP4056 in parallel.
This looks like a really bad idea. FIrst of all, BMS = Battery Management System, the first modules in the video are BMS but the one that was chosen is a CHARGER. Second, it uses the TP4056 chip which was not designed to operate this way, and could cause all kinds of problems, including causing the batteries to get on fire or explode.
thanks for the honesty. I would like to have your opinion on this thought. What if each battery has a its own protector board. like cellphone batteries. anyway the purpose of charging them with the proper 4.2 limit but needing the 8.4 +/- volts for instance of using 2. I assume not to try it. If not, could you guide me in the direction of figuring out how to use 2 cell batteries in a series and being able to charge them safe. hopefully a DIY way. i have no budget to work with
This is cool. I fooled around with this idea but didn't think of diodes to isolate the boards. This should be good as a low current battery supply (500mA) because the boards can only switch about 1 amp through their output circuits and the diodes are 1 amp. Each board contains two circuits. One shuts the input voltage to the cell off at 4.2 volts. The other circuit shuts off the output voltage when the cell drops below 2.9 volts.
With that connections you are actually shorting the chargers as you see when you plugged them in the chargers that has the current led on , (red led on), cause you are shorting them with the connections that you made so its a bad idea to use them like this. Keep doing videos but learn from your mistakes!

Hi Dream Finder. These individual battery protection circuit boards can handle a max of 1 Amp. Would there be a problem if I make this same 3nos series circuit for 3nos 3.7v battery and use it for my UPS? The problem I am concerned about is if the UPS 14v charging voltage is 3 or 4 amps. Would it blow the circuit I have made? What is you take on this?
i used a separate charge source for the 12v batery pack. and use a full bridge rectifier on the battery to ups. that way the ups can't charge the battery but can draw power from the pack.
Hi, I loved your project, excellent, congratulations. I would like to use this idea of yours. Could you please answer some questions for me? I'm going to replace the 6v lead battery of a children's electric motorcycle with a 18650 lithium battery. I'm going to make a 2S pack. Can this project of yours be done with just two cells? Will I have to replace any components? Thank you very much for your attention. I wish you to continue with your projects. A hug
I have a 3 S BMS. How can I use that as a 1 S BMS.. Basically I want to put 2 cells in Parallel and use a BMS for that. Need atleast 3 Ah output I need
Uma gambiarra que não vale a pena fazer. Melhor gastar um pouco a mais e ter um BMS com balanceamento, além de ficar muito mal o posicionamento, podem ter queima de componentes e até uma explosão de uma ou mais baterias.

this is not 3S, you are charging the battery 1S, you just used 12v as input.. 3S is series of 3 batteries, and you are charging the batteries individually. misleading title..

I like this crazy mad engineers way, not sure how safe is this before anything explodes or catches fire, but it does give good ideas 🎉
If two batteries charge before the third, the third charger Will get all voltage, só it Will burn,,, consider that current stops While batery is full.
not like that.... if if two batteries charge before the third battery will never charge... bcoz it will get get enough current to complete third battery charging...
Kids, don't try that, it will only damage your batteries and charging module. Be safe when play with li-ion batteries and get a proper BMS and charger

Батареи не соединены вместе. Если их соединить как в батарее электроскутера, произойдёт короткое замыкание.

what if you dont install the diode? what will happened?
Готовая плата мягко говоря лучше, учитывая сколько она стоит. Она ещё и как защита работает, а тут ерунда полная выходит
