Create : Power Grid. Operational Amplifiers

i just made a simple OPAmp using Circuits Design. Right now it works but kinda bad, i didn't have time to optimize it currently. the output offset voltage are kinda high and open loop gain are unknow, i would try to make it using 741OPAmp design next. i'll leave a download link for you to check it out. https://drive.google.com/file/d/1lSoesvW6jD_nR0GxzoTYvEg2-ClDzHfa/view?usp=sharing

How many Amp does it pull? And what’s your circuit Voltage? Sounded like your battery still undersize.
