I made a SEX Video for you - Strange Electronics eXperience:

Measuring the voltage between the batteryholder's plus and the IO board's plus when Servos are moving - the voltage over ONE connection (wires, switch, pin) is about 0.1 to 0.4 volts.

Assuming the minus side is the same then there are up to 0.8 volts eaten by the wiring between battery and servo connector.

So basically your saying that the servos draw enough current to rob the 5 volts needed for other components. If you added neo pixels, an amplifier, etc. The the robot may not work with all 7 servos firing at once. Good print job on the Lee.

wow 0.8V is really big waste just from cables

Birger T time to shorten our cables then. Just make new dupont connections. I'll try it with the bulk robot.

Bill SCHONFELDER don't do foolish things, shorten the servo cables would help nothing. The measuring was at my installation, may be you will get other results.
Camilo Parra Palacio there are not only these 0.8V, when measuring directly at the battery holder I have 6V, when switching the servos on the voltage drops down to 4.3V (at the battery holder!). So I made another measuring at the V and G pins of IO board = 3.2 to 3.6V remaining (and the servos are still working but without load).
