Recently I have been trying to do a project for my end of year project, it involved making a humanoid arm. 

I am still a newbie at these things, I usually have my friend do the wiring, but since he is away for the moment can anyone help me with it..?

I am currently using 6X MG996R Servos for each finger and 1 for the wrist. I am also using a Arduino Mega with a Adafruit 16-Channel 12-bit PWM/Servo Shield - I2C interface. 

I have already searchsearched through the web for the best way to power it but iI only found people trying to power it with a 5v adaptor, my problem is imI'm trying to make the hand mobile so I need to use a battery, i. I have tried 2x UltraFire 18650 3000mAh 3.7V rechargeable battery in series (Stillstill doesn't work only 1 servo moved), also using a 9v battery (Only moved 2 servos). 

So i have been wondering if I could utilise the Adafruit 16-Channel 12-bit PWM/Servo Shield - I2C interface..

Trying to power multiple servos at once using a Arduino Mega
