Battery recommendation

[BennyWLF]

Hi all!
I'm building a Genius XR4E and not sure what batteries to use.
Got a Max5 G2 combo 800KV for it
Would like to run it 8s with some decent runtime 25-30min if possible
Thanks for your answers!

I use PowerHobby 4S 100C 8000mah packs with QS8 plugs to make an 8S setup with the Max5/800kv setup and they have been great.
