What is the power of the TPA3116D2 amplifier

Hello, I would like to make a portable speaker powered by 10 cells 18650 based on such an amplifier https://m.aliexpress.com/item/32711415303.htmlwhen connecting 3 speakers of 4 ohm this drum the amplifier had 2 * 50w + 100w and will it play I have converters so you don't have to worry about proper power supply. I know there are instructions for this system but I don't write everything there!

Hello,
and where will my colleague take this 200W to power this amplifier assuming 100% efficiency of the amplifier and converter?
greetings

The amplifier needs 24v and 4a so wrote in the announcement and that's how much the inverter will give

So what if the inverter will give you so much? The inverter does not generate electricity from anything, you have to supply it with something. 200W is the only car battery that will be able to deliver for a reasonable period of time.

Besides, as I wrote here:
https://www.elektroda.pl/rtvforum/viewtopic.php?p=16210928#16210928
all necessary (and even more) data is in the system catalog card. Nothing can be found that contains more data than the integrated circuit manufacturer's official document.

From 10 batteries 18650 each 2000mah or 20,000mah = 20ah and the power from these batteries goes to the converter for 5v, and then to the next converter that produces 24v and 4a, and for comparison the car battery has 7ah and 12v, I think that my batteries will last longer

Are you kidding? Who told you that? 7Ah, they have batteries from UPS. Car batteries have at least 5x as much (the smallest ones are about 40Ah, and such for vehicles with diesel engines even after 70Ah).

First of all, the amplifier would give 200W in total, which at 24V gives not 4A, but just over 8A of current.
Secondly, 20Ah at 3.7V gives 74Wh energy - that's all you have accumulated in batteries.
Thirdly - the amplifier needs 200Wh of energy within an hour, i.e. almost 3x as much as you will have accumulated in batteries. As you can easily count, the amplifier with full power will be able to work about 1 / 3h or about 20 minutes, assuming that there is no power loss.
Fourth - two converters, one from 3.7 to 5V and the other from 5V to 24V is a waste of some 10-20% of energy accumulated in batteries, which will further reduce working time.
Fifthly - 200W at 3.7V means 54A - you would have to use average thumb wires for 18650 cells.
Sixthly - where do you get the converter, which you connect to the rechargeable batteries and get 5V / 40A at the output.

Exchange further?
Buddy, this is no magic, it's just physics at middle school level ...

Everything is cool but where did you get the 5v and 40a converter and I wonder what amplifier would have such current and secondly I can safely add batteries

Added after 11 [minutes]:

A and 18650 cells have a nominal voltage of 3.7v and a maximum of 4.2v. You may have heard about the jbl xtreme speaker which has 10000mah has a power of 40w and according to calculations per hour would charge 40wh and the battery will give it 37wh so it would play about 1h and the manufacturer will provide 15h az tests on 100% volume play 12 hA in my speaker, so in xtreme there are class D amplifiers, which are characterized by high efficiency at the level of about 90%, which in my case would be 180w, and their second feature is low power consumption. I don't know if it's good I think if not, please correct me.

Everything is fine but where did you get the 5v and 40a converter

From the power balance, sir ...
If the amplifier gives 200W then 200W must download (assuming the ideal case - 100% efficiency). At 24V, 200W means 8A, while at 5V - 40A, at 3.7V is 54A. Simple math and a simple school formula for power.

The amplifier cannot withstand the current, the amplifier consumes it ...

Yes, I even had it in my hands and unfortunately the case is quite different than you write.
According to the manufacturer's specifications:

Rated power: 2 x 20 W bi-amp circuit (AC mode)

AC mode - i.e. when powered from the mains, not from the battery! With this power there is one more myk, but I will not write about it, because at this point it is completely irrelevant, besides without knowing some issues in the field of audio you will not understand what is going on.
And from the network, the power supply looks like this (via an external power supply):

Quote:

Power supply: 19V3A

So 57W! Takes 57W and gives 40W despite class D amplifiers.
And the battery only like this:

Quote:

Battery: Lithium Polymer (7.4 V, 5000 mAh)

Do you see the difference?

according to calculations, he would take 40wh per hour and the battery give him 37wh, i.e. he would play for about 1 hour and the manufacturer provides 15 hours

The manufacturer shall provide this information:

Quote:

Music playback time: up to 15 hours (varies depending on volume settings and audio content)

Up to 15h, this does not mean 15h.

akumulatorek wrote:

tests for 100% volume for 12 hours

And how do you know that the speaker worked at 100% volume? Just because you had the volume control set to 100% does not mean that the amplifier gave full power.

in my speaker yes in xtreme are class D amplifiers, which are characterized by high efficiency at the level of about 90%, so in my case it would be 180w

And how should the amplifier give 200W by downloading only 180? Completely the other way - it will give 200W, but it will charge 220 instead of 260W as it would be in class AB.

akumulatorek wrote:

But not less than as much as it gives to the speaker.

Sorry, buddy, but I have to ask - how old are you?Have you ever studied physics? What we are writing about here is nothing more than a balance of power, and this is a basic issue in physics and they teach it in schools from the very beginning in physics lessons.
Unfortunately, you have huge problems with these basic issues ...

And maybe there is also such a thing as capacitors and transformers that accumulate energy and later give off more of it. On all advertisements and instructions of the tpa3116 system it is clearly written that this system works in the range of 18v-25v and the maximum current is 4a

Added after 40 [seconds]:

However, the producer probably knows better than you do

Even if that were the case, the current drawn from the 3.7V battery would still reach 30A.

akumulatorek wrote:

Of course the producer knows best. That is why I do not read what was written in an advertisement, but what the integrated circuit manufacturer wrote. I gave the link, but I see that you completely did not want to look there.
And it is clearly written:

Quote:

Supports Multiple Output Configurations

2 × 50 W Into a 4-? BTL Load at 21 V
(TPA3116D2)

and:

Quote:

Wide Voltage Range: 4.5 V to 26 V

http://www.ti.com/product/TPA3116D2
The manufacturer wrote that in the BTL configuration you can get 2x50W at 4R. So with 4R you can do 2x25W + 1x50W which gives a total of 100W. However, there is a certain detail - the amplifier can work in a PBTL configuration and then having two such systems it is possible to obtain 1x100W at 2R and 2x50W at 2R, respectively, which gives 200W.
The supply voltage range as above 4.5 - 26V is also given.

Everything is clearly explained here:
http://www.ti.com/lit/ds/slos708e/slos708e.pdf
which I have to remind you once again ... Will you finally get to know it?

As data integrated circuit manufacturer do they relate to data that you found somewhere in an advertisement? Who is more reliable - some advertiser who sells the Chinese module, or integrated circuit manufacturer ? Do you believe in offers or producers and physics?

Okay, ok, I agree, but we departed from the topic. Above you wrote about some configurations. But I don't know what it is about. Please answer the question, so if I give three speakers of 4ohms, how many watts will the amplifier give and ask for generator settings ( I mean amps and volts)

I don't see any deviation from the topic here. The theme is to power the amplifier on the TPA3116 with a battery. All current and voltage values have already been listed several times here, as well as output powers.
The only deviation from what we are discussing you did:

akumulatorek wrote:

I would like to ask for generator settings

You have not mentioned the power supply from the generator before and I do not quite understand what it is and how you imagine it. Power generator do you want to buy / build?

It is not about the fact that the batteries will be connected to a converter that can process max 36v and 10a. And it is about how much of this converter is to be fed to the amplifier

How much is 24V or 21V there, as provided by the integrated circuit manufacturer. You won't limit the current anyway, the current will limit itself. The amplifier will not take more than it needs.

As I can see, basic physics is foreign to you all the time (that's why I wrote so much about it) and you still do not want to acknowledge that the current drawn from a 3.7V battery will be at 30A and more ... You must use wires with cross-sections 40mm, do you know that? Batteries are designed for a continuous discharge of several amps? As I know life is not, and you have probably not heard of such a thing as the dependence of capacity on the discharge current?
Sigh ...

Just tell me how many watts the amplifier with three speakers will have, each 4 ohm so difficult to answer this question

But I've already answered 4 times giving official data from the integrated circuit manufacturer.
Dude, do you have any problem understanding your written content?

And what is the PBTL configuration

Buddy, you have everything written in the integrated circuit manufacturer's documentation. I see no reason why I should quote subsequent passages here, and rewrite what is already written there.
