Looks good. Though in my experience, I'll say to remove those wires and bite the bullet and spend a little more on some off of Amazon.
The ones from China arrive like 2 weeks after everything else does, and then you'll have issues where the wire straight up breaks off at the solder point. In addition, having everything color coordinated helps a lot, so I'd recommend getting a multi-color pack.
I have no experience buying the batteries from aliexpress either, I ordered mine off of Amazon since the batteries from China were usually pretty low on amphours (I ended up with 12ah which lasts me about 13.5 hours for about 25usd)
Other than that, and the cases which I assume you're buying elsewhere or building yourself, you appear to be good to go!
