i have a 450, I was running a 3s 2200 battery and getting about 8-9 min out of the battery before the red light came on. Today I got a new 3s 4000 battery and got about 9 min out of it. I didnt think the weight was that much of an issue? Also I read somewhere you need to break in a lipo? Also when I charged it, it only put a little over 2000 back into the battery? Do I need to do something to break in the battery? Or should I get a lighter battery?

1.The takeoff weight  range of F450: 800g-1600g. So the weight is indeed a issue.
2.no need to break in the battery. 3s-4s lipo battery are both OK.

They don't store/ship lipos fully charged.
You should not either for long periods.
When you get a new lipo, SOP is to fully charge it before use.
They require no break-in...

I am using a 4S 3700 14.8v LiPo and when my charger (ImaxRC B6AC) finishes,/ beeps and displays "Full" and I measure the voltage of my battery, it's at 15.8v. Is that normal? or am I over charging it?

Hi,
I think the charger brings the battery to 4.2V/cell or in the 4S case 16.8V for a full battery.

How do you put a little over 2000 back into the battery ? About 3s lipo battery, when you charged 2000mah , the voltage isn't 3s , so your battery doesn't have enough power to support your drone . You 'd  better change a new 3s lipo 2000 battery.
