Hello everyone,
I'm trying to power a fairly powerful servo motor, an RDS5160, I'm a beginner and therefore I couldn't find the correct way to power it, can anyone give me some advice?
Thank you
Looks like you need a 7.5vdc 5A power supply.

A 2S Lipo battery would be perfect

Thank you everyone for the advice 
!
Does anyone have any videos/websites they can recommend to then connect all the components? Because searching on the web I haven't found anything useful for this type of situation.
What is your application? Can you plug it into a wall socket? Or do you want to take it with you?

Which Arduino are you using?
DroneBot Workshop has quite a few good introductory videos on various Arduino uses.
Ralph S. Bacon and Paul Mcworter are two other names to search on YouTube.

Initially to do some tests I would like to connect it to the wall plug, but in the final project I would like to be able to connect it to a battery. I’m using arduino Uno.
Thank you, I will watch for sure
If planning on LiPo, a 2S should do it as jim-p stated above.
The AC to DC is a different story. Mains power to 7 to 8vdc 5Amp.

You should not buy a "strong" servo motor, just because it is strong. Because now you have to find a way to get that 5 amps available for the servo motor.
You should buy a servo motor that is suitable for your project.
A servo motor has a gear, that makes it strong.
So I repeat the question by SurferTim: What is your application?
Please give us a broader view.

The servo motor in question (with a metal shell), I would like to use it to move a solar panel (about 4kg). This movement will be done around the x-axis (and a stepper motor will do the rotation around the z-axis). All this to create a solar tracker. I decided to use this model of servo motor since the moment of force at the lowest points is high, but if there are better solutions I am happy to use them 
I hope I explained good the project.
After listening to your precious advice I am inclined to carry out my project like this, thank you very much.
A balancer on the panel might reduce the power requirement significantly.
It does on entry and exit gates. Notice they have a weight at the short end?

Have fun!
Both stepper motors and servos consume electricity while standing still. Servos especially if there is wind trying to push the panel away from where you have it positioned. Careful analysis will probably show that the gains realized by tracking the sun are outweighed by the power needed to do so.

Does your design allow for the stepper and servo to be continuously powered? That is 24/7/365. A better design would use a motor driven lead screw that will hold position with no power required.
I am aware of the problem of excessive energy consumption, but the aim is not to produce energy efficiently, but rather to measure the efficiency of a solar tracker compared to a standard solar panel that does not move.
