My Quadrotor do not lift high

I'm working on a 600-frame drones, and I have a problem that does not hover.

It lifts for about 10 seconds immediately after I fully charge the battery. After few seconds, however, even if I raise the throttle to the maximum, it does not hover anymore and land to the ground.

After that no matter how I throttle up, it does not lift.

I have changed the PID gain and pixhawk parameters, but there is no big difference.

I have tried to solve the problem by reducing total weight about 200gram, but it shows the same behavior..

Quadrotor's configuration is as follows:
850kv motors, 5000mah 3s lipo, 35a esc, 600mm airframe, and 1.3kg total mass.

Do I have to use 4s lipo battery?

I attached image depicting wiring configuration and video showing the behavior
