Help for KK X, please

Hello everyone.
I trying to make my first quadrocopter.
I need advice as your help.

Controller KK X Multicopter Black v5.5
4xESC 30A
4xMotors 1200Kv (250W)
4x Propellers 1060

Firmware: kk multicopter v5.5

I calibrated ESC
then i calibrated KK Board
i tested this board without propellers, shows me all super! ... untill

i set the propellers.

When I've used propellers, and the throttle is between 25-40% operate, everything is ok. The controller (X Copter) works as it should in the datasheet. But if I set throttle position about 50% , two motors failed, if i changed this position further to 80-90%, still worked just one motor.

The question is: not sufficient to power? I use now NiMH 4800 mAh 7.2V
I can buy a lipo 11,1V 5000 25C but i dont know, if i can reach a better result.
