What are my stationary options here? What is my mobile options?

I am powering 23 hitec servos, for now I just need something for a demo. Later on I need some kind of battery powered option.

Thanks in advance.

Before any answers can be given you need to know (and tell us) the voltage and current these servos require.

Eh, stupid mistake. 4.8-6V, and I am unable to find current information. :/
Torque (Kg-cm/Oz-in @6V): 72/89 -- digital servo.

Do you have the model number from the servos?

Well you will need to know that, if not from the data sheet then from measuring it. It is also best to measure it under full load. Then multiply up by 23 to get the total load.

At a conservative guess of 200mA per servo then you have a total current of 4.6A which is quite a lot. For 5V this is 23 Watts.

So for mobile then a lead acid battery might be good, you could get the 6v motorcycle ones.

For fixed then you are looking to convert / use a PC's PSU.
