flight time

I've been looking into building a mid-range quad that gets around 8 - 10 minutes of flight with mostly cruising and maybe some smooth acro flying. I like quads like the explorer lr 4 inch, but there's a lot on it that I don't care for, like the deadcat frame, gps, or HD fpv. I don't mind analog...

I am making a 250mm 3d printed fpv quad. Weighs 600g without battery. Tmotor 2207 2250kv motor used, 4:1 thrust ratio at max. Want flight time of around 7-8 mins. What capacity battery should i use?
