OPTO esc is with 2 wires. (Yours)
BEC is with 3 wires.
You can just plug in those 2.(black to (-), white to (S).
BEC esc is when you want to power your FC with esc.
How can I know if these motors are CW CCW? They are just selling these ones. I am newbie, so this question might seem stupid.

Okey thanks. But now I understood that I can max get 25A for motors, because I have 10000mAh 10C LiPo (100A current from battery /4 = 25A). I guess I will have to buy new 10000mAh 25 C for more current :(.

I am using these. Well... is it bad i use only 30A from 40A esc ?
I need to connect my 4x40A ESCs to my battery for my quad, however I couldn't find any distribution board for that high current (40x4=160A). Maybe I am doing something wrong?
Well yeah you are right, but... I wouldn't use 100% of motor power, although i would still get decent amount of thrust and time right?
Here is my calculations for 30A ESC and 12 inch prop with multistar 800KV.
