Power Expander

We are planning to add a power expander to our robot, but idk how many motors it will power if our main battery goes dead.

What are the main advantages of using a PE? And how do i attach it properly?

Below is the way our motors are put into the cortex.

#pragma config(Motor, port2, backRightDrive, tmotorServoContinuousRotation, openLoop, reversed)
#pragma config(Motor, port3, BackLeftDrive, tmotorServoContinuousRotation, openLoop)
#pragma config(Motor, port5, Intake, tmotorServoContinuousRotation, openLoop)
#pragma config(Motor, port6, Flywheel, tmotorServoContinuousRotation, openLoop, reversed)
#pragma config(Motor, port7, Convayer, tmotorServoContinuousRotation, openLoop)
#pragma config(Motor, port8, flywheel2, tmotorServoContinuousRotation, openLoop, reversed)

how do u wire it??

You don’t need a power expander you only have 6 motors. Why do you want a power expander?

so it will last longer.

i dont i have 10

Oh sorry my dude I thought you were using v5


port 9 8 and 4 have two motors together

We had a power expander on our old bot just because our batteries were old

is a power expander good so we dont trip pcts???
