I don't quite understand your question, but you can control digital servos exactly how you control an analog servo . . .
No one can answer my question here. AXON support 18 servos? How to wire up the batteries? If not, forget it. Not going to use AXON...

How to wire up the batteries?

So, one battery could handle all 18 servos? That will be pretty cool if AXON could manage such voltage. If not I might use second battery for servos. Is it possible to do?
Thanks for the help!

The voltage is the same... You're wiring the servos in parallel - all your battery needs to do is to be able to handle the current draw.

Any suggestions for what type of battery if I am using 18 servos?

What kind of servos?
For example, lets say you have 6V servos that use about 0.5A. That means your battery needs to output 6V at 9A (18x0.5 = 9).
You can also use two smaller/weaker batteries in parallel on the Axon for 2x the current.

Great~ Good to know and thank you.
I have digital HS-5645MG and 645MG servos. So, I have two 7.4V li-po 2800mAh batteries in parallel and that should do the work right?

You will want to regulate the 7.4v LiPo voltage to a more reasonable five or six volts - a switching regulator (RC BECs work well) would be fine. Servos tend to not like getting extra voltage - you might burn something out, and these aren't cheap $10.00 servos either. Other than that, it'll be good.

Yap, I do have a switch regulator to reduce volt down to 6V. I have burned 3 servos to learn that while ago. :(
