Hi I have a power expander pro in a model with 6 servos HS 7955, I am using 2 batteries NIMH 6V 2000 mAh, you should insert a Super Reg or no the Power Expander consumption can handle the amps

Hi,
This is a servo question, not a Pro question. The PowerExpander Pro can handle up to 8.5V input and has no real limit on current (amps). The regulator would only be needed if your battery voltage is too high for your servos. You need to determine that from your servo specs.

Thank you, pardon could not answer before, but now I understand the operation of the power expander
