Wanted something robust that my son could fly and that I could also use indoors in the winter. But I'm getting little more than 2 minutes of battery time.

I just have the same autonomy on 350mah 3s batteries (6500kv motor). Big batteries do not offer any significant increase (3min15 with 800mah). Your 2s 1000kv setup requires more amp draw and "weak" batteries won't make it. I doubt the 350mah would survive for long, and bigger ones will add to much weight. For now I would give a try to the HQProp 3 blades: they are more efficient than FFPV props.

Maybe the batteries are too heavy? How much does your rig weigh?

I think you're just overweight for those motors. That's a fairly hefty frame and you're only running 6500kv. Maybe 2 minutes is about as good as you'll get. I don't think heavier batteries will help.

Actually, the 6500kv is a mistake. I'm using the 10000kv motors. But to be honest I have no idea the difference between the two.

10000kv has more rotations, so it's faster essentially, but it's all a balance of kv, prop size, weight and mah.
