Thank you for the excellent demonstration. I think there is lot of misconception regarding the function of BMSs on the internet. I always though that the balancer keeps the same voltage on each cell connected in series no matter what state of charge they are in. Thank you very much for clearing this up for me.

You are a genius and a gifted teacher

Thanks Robojax for a top presentation. I was educated and entertained.

great video and explenation ;) will definetly use one of these balancers for my 12v 18650s ;)

Herzamanki gibi mükemmel bir video olmuş. Her saniyesini keyifle izledim.

Another great video!

Thank you so much! Video is very useful!

superb explanation !!!!! thank u

خسته نباشی احمد جان عالی بود

Can you add two 5 balance circuit board to make a 10 batteries balanced in series?

Can I connect in parallel another resistors for faster discharge and balancing?

Great video nicely explained. Thank you. Could you please explain how to connect charging module and balancing module in to a 3S battery pack

Nice explanation anw, - so it usually called bms, right? & what's diferent with battery equalizer??

When do the balance only boards start balancing? Most BMS only balance at near 4 volts, id like the balance to start early, maybe anytime it is charging, although I guess it is more efficient when the charge current is greatly reduced, at near full charge. I think anytime it is charging would be better, (* sorry you answered most of my questions,* )

I am a beginner in this topic. You have excellent videos and they are all very informative. I watched the full length of this video and you said that this balancer when used should not be connected to a charger. What can you recommend to use as a balancer at the same time a charger with OV, OC, UV protection features? Sorry for the newbie question.

so how can we use this ?? add this to a bms with no balancer ?? i have a 4s 40A bms enhanced version without balance ..can i solder this to the bms ??

Thanks for the effort in creating this informative video. I am searching for how BMS balancing works and your video gave me a very good concept. In your video, you demonstrated how the balancing works and showed the 66mA current for one battery. Do you know how much would be the current or how it would flow when two batteries (say, battery 1 and 2 which are next to each other) are doing balancing? How much would be the current value and what are their direction on B0, B1 and B2 lines? I am new in learning electronic so please forgive me if this is a dumb question.

Can you review the 5 amp active balancer capacitor type

What does balancing a single cell actually mean? Isn't the point of balancing to even out the difference in voltages between cells in a series pack? If there's just one cell then what's the point of using a balancer? I'm new to working with batteries and want to learn as much as I can before even actually touching one.

Is there a way to changing the balancing voltage on these balancers, by replacing the R5 resistor maybe?

Amazing. Explanation was very useful. Sir I have question, I've been looking for the answer. Does it support balance discharging, as it use to balance charge, because I have a 3s4p battery which I use for backup of my router, but I also want to add a mobile power bank board which uses 3.7 to 4.2 voltage, can I connect it's terminals with B- and B1 whare voltage are 3.7 to 4.2 (1st cell) while also using 12.6 voltage also for sometimes,also tell me if I do something like this and charge my stuff using that powerbank module then will it consume first parallel 4 cell or the whole battery pack by synchronizing with other cells in series. Please tell me , or please test this for me and others if you can. I'll be very thankful to you. And also one more thing.

And the active balancer inductor type

that's means all of balancer power loss of all cell! so it's passive cell balancer! what's solution about active types cell balancer

if i repair laptop battery and using brand new battery for replace old battery can i simple them balance without any electronic only connecting them in parralel and then replace cells?

Hi Ahnad, very interesting your channel. I whish to know if you have any project whitch charge a Li-Ion 18650 arrangement 1S 5P or more parallel Cells, using a different board from TP4056. Thanks. A best regards from Argentina

can you add a parallel resistor with the 62 ohm, to increase the balance current? say a 220ohm to get a slightly higher balancing current? it looks like the FET would be able to take it.

Can i use this 8s board for 8s Lifepo4 battery?

Dear Robojax. I have a question for you please. I am trying to use the same 40A 3S balancing board on my 3S pack. It has 43 Ohm balancing resistors also. My pack is off balanced and C1=3.6V, C2=4.1V and C3=4.0V. When I supply the charging voltage (12.6V), the C2 reaches 4.2V after some time and starts dissipating heat through it's balancing resistors. At this time, the charging is also becomes OFF and the other two batteries don't get a chance to raise their voltage. So, I am worried about how the balancing is supposed to work in a well off-balanced pack like mine. Can you please explain.

So in conclusion, is this balancing module worth it or not (66mA version)?

66 mah of balance in 4.23 is not very little it does not reach 10% of the capacity of the battery. To properly balance a battery it needs to operate at 4.1 volts at a current of 10% of the battery.

Can you do active balancing?

Can we use it as 2s balancer?? Please reply

happy Ramadan Ahmad

Where is turkish subtitle ????!!!! 😑😣

Please replace “charger” word in your video with the proper one, which is “BMS”.
