what battery would you recommend for powering 10 servos at 6v ?

I am currently working on a humanoid robot and am trying to ruduce the weight and increase the opperateing time I am useing 4 AA batterys to power the top half 12  servos and another 4AA batterys to power the bottom half 10 servos  22 servos in total . The AA batterys tend to go flat quite quickly and haveing 8 AA batterys make the robot heavyer also if i could recharge the battery it would be a great help. the servos are rated at 6v maximum and 4.5v minium what would you recommend ?

Any help is greatly appreciated.

how to send sensor values wirelessly

i know how to send messages to another arduino but im not sure how to send sensor values here is code to transmit the word hello 

If you could show me an example code it would be great.

// transmitter.pde


// Simple example of how to use VirtualWire to transmit messages

// Implements a simplex (one-way) transmitter with an TX-C1 module


// See VirtualWire.h for detailed API docs

what is the best way to communicate wirelessly from one arduino to another

I have 2 arduino megas and would like to send the potentiometer values of one arduino to control servos conected to the other arduino and I have never used any wireless things with arduino before I have a 433mhz transmitter and a reciever but havent been able to find any useful code for it and was wondering what other wireless devices i could use for sending potentiometer values wirelessly to another arduino easily . Any sugestions and example code and where to buy it would be greatly apreciated thank you
