I must be misunderstanding something, but when I see motors such as

It says that the needed voltage is 4-6s, that is 14.8V minimum.
Now, how can a 4s battery, supply FOUR 14.8 Volt motors?
Wouldn't the required voltage need to be 4*14.8=59Volts?
I must be misunderstanding something, because splitting a 14.8 Volts into four different paths, using a power distribution board, should theoretically create 4 paths with 14.8/4=3.7Volts each, which is far below the required voltage for the four quadcopter motors.
I hope someone can clear this up for me because my lack of understanding is getting on my nerves
thanks,

Yep, was switching up the effect of a parallel power supply on Voltage to Amps, brain glitch.
Your calculations assume a series connection.
(1) Maximum average voltage, the actual average voltage is varied by the ESCs using a method known as Pulse Width Modulation, and is roughly proportional to the resulting motor speed, and hence thrust.
