Amazing project! Alteration of the radio-controlled car on lithium

In this video, we will remake the radio-controlled machine on lithium-ion batteries. Be careful, when assembling the circuit, follow all the conditions set forth in the video. I tried to make the video as clear as possible even to beginners, so that they too could make the project, because there is nothing complicated. There are many vidos with similar homemade products, but I have not seen a more detailed description of the actions and components used. Links to components are in the description.
