It would appear that you may want to look into getting 7.4 volt battery packs instead of 12 vdc packs. They also come with different amp or milliamp capacities and can be connected in parallel to provide more amperage without raising voltage.

That's what a'm going to do. i was tired and knew better. hard lession learned, think before you punt.

@ merne, I have had my InMoov robot up and running for about a year (on an Arduino based OS), however, I am in the process of switching it over to run on EZ-Robot. Here's how I am powering the robot. I have 2 - 6 volt 12 amp hour batteries connected together in parallel, the power from the batteries go to a main bus bar. All of the servo power + & - wires are connected to the bus bar. All of the servo signal wires are connected to the EZBv4. A ground wire is connected from the battery power supply to the ground pin on the EZB. I am also powering the EZBv4 from the batteries. There is an on/off switch between the batteries to the servo's and one between the EZBv4. This way the controller can be turned on and connected before powering up the servo's. This type of set up works great and provides lots of power all 24 servo's in my InMoov.

I hope this helps.

Can you please take a photo of your setup? My EZB does not like running on 6V at all. I think I need to give it more power, but the the servos fry after 6V, so they need to be wired around this microcontroller, which is really annoying.

@BHOUSTON "I have 2 - 6 volt 12 amp hour batteries connected together in parallel"

Slightly off topic, just wondering if you have any easy method to recharge them? Or do you have to disconnect them and charge them one at a time?

I don't believe @Zxen's troubles are power supply related, see this thread.
