Python uses references so you can have a Sprite in a batch and still
keep it in a different place (ie. a list of entities). When you update
the position of the Sprite in the list, the Bath will draw it in the new
position.

I don't know if there's a better way, but that is how I would do it :)

Sorry, made a duplicate post as I didn't know sure that it was submitted (until I noticed that it had a delay!). 

I know that's an option, but then my entity can't have a seperate Position component and I'd need to update both. I'd like to avoid this (not a great issue but was curious if it would be possible...)

Well, that's up to your design. Your Entity class could derive from a
Sprite so you can use the x and y properties of that class as position.

You can't avoid that. How else the sprite vertices info in the batch would update ?

pyglet sprites hides the vertices updates, that is, you can update position and let pyglet care to adjust vertices but thats all.
