<p>So I am designing this octocopter which can lift up a payload of more than 50kg, min 50kg for an intra-city package delivery drone. From what I figured, with 8 motors, the safest thrust needed will be 2.2* whole weight of drone / 8 which corresponds to 16500 g of thrust.</p>

<p>The maximum current draw from the motors will be 909.8A ( from the table), however, I am not sure about the optimal battery and ESC to use.

Not to be a party pooper, but given your questions and lack of experience with drones, I think you are WAY above your head. Start small, learn, go to the next level.

Indeed thank you for that.. but I never actually plan to build one. I recognize that to build an actual prototype of this scale would need a team of experts from different proffesionalities. It is design work and this is all for myself to gain experiences in modelling and simulation, and working alongside my friend who’s an aerospace engineering student. However, I want to see what actual components are available to make this drone if it were to be scaled from a smaller size.

The over 900 A should be a pretty clear indication that you'll need motors and batteries with a lot more voltage to produce that much lift, or you'll also be trying to lift 50 kg of copper to carry all that current around.

Maybe use diesel engines like in this video: https://www.youtube.com/watch?v=soxxPyaAT1k
