Hi is it possible to connect two different ah battery in parallel for example the first battery is of 10.5 Ah and second battery is of 7.5 Ah can we connect this into parallel connection plz reply for this
Hello Sir, can you help me I have 4.2 volts 8000mAh batteries, how many batteries do I need to create a 12 volts 50,000 mAh battery pack, and what is the layout, do I need a special BMS, thanks.
The “C” rating is a concept that is applied to batteries based on their Ah rating. 1C = whatever the cells capacity is. (Omit the “hours” part of the capacity rating) For example: an 18650 with a 2500mAh capacity rating would have 1C = 2500mA or 2.5A But a different cell with 1500mAh capacity rating would have 1C = 1.5A Another example: let’s say you have a 1S8P battery. Each cell is rated at 2000mAh. So the total capacity is 16,000mAh or 16Ah. For this 1S8P battery, 1C = 16A. See how 1C is different for every battery? It just depends on the capacity if the battery. Why is this useful? Because some batteries can discharge at 10C, while others can only discharge at 2C. Knowing your cells limits are important. The same goes for charging… you’ll often see recommendations to charge at 0.2C for best results. So you would need to know what 1C is, then divide that by 5 to get 0.2C. Last thing I’ll say is that the “C” rating capabilities of a lithium cell are highly dependent on its chemical composition. Some cell chemistries can output huge currents without burning up. Like the Sony VTC4. Try getting 30amp out of a different chemistry cell and it will likely explode after it heats up to the critical “thermal runaway” temperature.
He constantly misused Amps with Amphours. Amps is a rating for how much current is actually flowing at a given point in time. Amphours is a measurement of capacity.(how long it can deliver current) For example: the Samsung 30Q cell has an Amphour rating of 3000mAh. (3.0Ah) However it can deliver 15 Amps continuously to your load. See how those are different things?
Hello, I am a mechanical engineering student working on the design of a radiator for an EV. I just want to ask how to calculate heat generation from a lithium-ion battery pack of 48 volts, 100 Ah, and 1.4 C (hours). I am searching but unable to get a satisfactory answer. Please guide
Hi thanks a lot for the explanation but I still a bit do not understand ... if I want a 72 volt battery with 60 amps an hour how many 3.7 batteries do I need and how many amps an hour? And to the best to connect them?
Nicely done. Now armed with the "I" and "E" of the cells in question what formulas do you use to calculate the Ah and Wh for the series and parallel cells as used in your example. How to calculate the 4series cells Ah and Wh and the same for 4p.

Bravo!!!!!!!!!! all way from Nigeria, i really enjoyed your teaching, please kindly teach how can we get twelve volts and hundred hundred amps from those battery
Thank you for your positive comments ☺️. For making 12volt 100ah battery pack . Use 21700 lithium ion cells . Each cell has 3.6volt 4500mah . Use 66 cells , 3s 22p . You will get 12volt and 99ah . Use 3s 100amps Bms for your battery protection. If you need more information +91 81486 45086 WhatsApp number . Just text me
Are you referring Ah as ampere or the continuous current draw as ampere,that should be explained clearly because in e-vehicle Ah and max current draw(C rating) both are important. And you explaining the series parallel in 2D plane it would be better if you explain it in 3D matrix.Other wise video is awesome.
Hi, I want to make a 12.6V 72Ah battery pack from 18650s and I´m not sure about charging current. It would have 36 parallel cells with 2Ah and charging C rating is 0.5, then maximum charging current would be 36A? Am I right? Thanks.
Thanks for watching and subscribing my channel . You're on the right track, but let's clarify it step by step. You want to make a 12.6V, 72Ah battery pack using 18650 cells. Each cell has a capacity of 2Ah and a charging C-rating of 0.5C. The C-rating indicates the maximum current you can safely charge the cell. Here's how to calculate the maximum charging current: Maximum charging current per cell: The C-rating of 0.5C means that you can charge each cell at 0.5 times its capacity. For a 2Ah cell: 0.5 C × 2 A h = 1 A 0.5C×2Ah=1A So each cell can be safely charged at a maximum of 1A. Configuration of your battery pack: You mentioned that your pack will have 36 parallel cells. In a parallel configuration, the currents from each cell are added together. Since each cell can handle 1A of charging current, for 36 parallel cells, the total charging current would be: 1 A × 36 = 36 A 1A×36=36A So, the maximum charging current for the entire 36-cell pack would indeed be 36A. Conclusion: Yes, you're correct that the maximum charging current for your pack would be 36A. However, remember that this is the theoretical maximum based on the cells' C-rating. In practice, it’s often a good idea to charge at a lower current for longevity and safety.
How many batrreyes needed for lithiminpo4 12volt 100ah and 12volt batrrey & what kend of bms have to conect & whare can I purchase this mettieal in best price😕thank you
Thanks sir but one doubt I have 5watt blutooth speaker it has 1200mah of 3.7 volt so the battery backup is low so if I use 2000mah of 3.7 volt battery what will happen does it run or damage to the speaker please tell me sir🙏
You're welcome! To answer your question, replacing a 1200mAh 3.7V battery with a 2000mAh 3.7V battery should not damage your Bluetooth speaker, as long as both batteries are the same voltage (3.7V). Here’s why: Capacity (mAh): The 2000mAh battery has a higher capacity, meaning it can provide more current over time before running out of charge compared to the 1200mAh battery. So, your speaker will likely last longer on a full charge with the 2000mAh battery, but it won’t affect the operation or cause any harm to the speaker itself. Voltage (3.7V): Since both batteries are rated at 3.7V, the voltage is the same, and your speaker's circuit will work as designed without any issues. However, a few things to consider: Physical Size: Ensure that the 2000mAh battery fits properly inside your speaker, as a larger battery might not fit in the available space. Charging Circuit: Double-check that the charging circuit in your speaker can handle the larger battery. Most Bluetooth speakers have built-in charging circuits designed for the original battery capacity, but this is usually not a problem unless you’re making significant changes in battery size or chemistry. In summary, swapping the 1200mAh with a 2000mAh 3.7V battery should not damage the speaker and will likely give you a longer battery life. Just make sure it fits and the charging system is compatible.
Hi Sir, this is Remedios from Goa, if I want to get (3.7v and 2430mah) in parrel , (for a sony xperia mobile) of 2 Lithium-Ion batterys what should I do? If the value of 1 lithium battery is 3.7v2200mAh in parrel the voltage and mAh will remain the same? Or the mah will increase? Please advise Please help!
Actually I have a query that can I use 48 volt 24 a in a parallel connection through which I can get that the 48 volt and the 1248 a so that will be suitable for a 48 volt 900 watt motor or not Another thing that is if I will increase the a then the battery loss is increased or it is the same Please tell me
Really superb explanation sir thank you so much my all doubts cleared by your video thanks a lot.. Sir can you please make a calculation on batteries connected in the combination series and parallel .. To increase voltage and current
If you using 3.7v and 2500 mah lithium cell then , 340 cells required to build 72volt , 42ah. Battery pack If you using 3.7v, 3000mah lithium Ion cell then, 280 cells required to build 72v 42ah battery pack
How would you calculate the battery size needed to run a 1000watt hub motor for 2 hours? Sometime i thought i understood, but then i got lost. Also whats to consider when choosing the spec of the battery, ie, 72V30A 36V20A ,etc
Friend my cordless imact driver required 7.2v 1.20A but I did 3.7 2A of 6cell in series to make 22.2v2A but the motor not runed in high speed and circuit changed to parallel 3.7 2A *6cell to make 3.7 12 A no use and changed to series parallel combination no use give some idea and in impact driver battery is lithium cadmium and I used lithium ion I think battery discharge depends to give more current
Its not 2A. Its 2Ah or 2mAh Ampere and Ampere-hour are two different things. Current is indicated as I and its standard is Ampere(A) For example: I = 4A Charge is indicated as Q. And its standard is Coulomb(C). The relationship between I and Q is l=Q/t
I really enjoyed ur teaching, even lecturer can not explain pretty like this, Bravo

So. Minimum motor 4 hr work
Its not 2A. Its 2Ah or 2mAh
Ampere and Ampere-hour are two different things.
Current is indicated as I and its standard is Ampere(A)
For example: I = 4A
Charge is indicated as Q. And its standard is Coulomb(C).
The relationship between I and Q is l=Q/t

there is no data of cuurent avilable in bateries ,only volt given ,then how to predict currnt
just divide voltage with watts you will get current 👍...or else send me battery pics ..8056248257
How mobile or laptops calculates the battery capacity into percentage?
👌 awsm
Good explanations
Thank you 👍
