Hello again my dear friend!

Here we will see what is explained in the description, but with images showing in depth about this file and its models. We begin by showing the low polygon that it presents, you can see it as the mesh is constructed, and smoothed with the sudivision surface modifier. 

The content of the file (models and elements such as lights or cameras) is carefully named and stored in their respective collections:so you can locate them very easily. Among these collections are the 6 scenes with their respective model, and a collection with all the 5 models without altering their transformations. 

Finally, we add that each scene is related to a void, which you can move the entire scene, without having to move each element 1 by 1. Likewise, each camera of the 6 scenes will be marked, which you can slide on the timeline to locate which scene of these 5 charger models you need to render, that easy!

Important!

Each Charge head is linked within its scene, in case you edit any of the 5 models, the one in the scene will also be edited. You can unlink and edit them individually if you like. 

In the previous image the three selected are linked. 

That would be all, any questions let me know!
